The sixth generation of the BMW 3 Series Sedan, the world's best-selling premium car, sets new benchmarks in terms of sporting prowess, elegance and comfort. The pioneering history of the 3 Series serves as inspiration for the new sports sedan, whose powerful styling represents a fresh interpretation and conscientious development of traditional BMW design cues. The new BMW face, wîth flat headlights reaching along as far as the BMW kidney grille, emphasises the elegantly dynamic design of the new BMW 3 Series. The sixth generation of the 3 Series has grown in size compared to its predecessor, wîth its wide track (front + 37 mm, rear + 47 mm) particularly prominent, and the car's increased length (+ 93 mm) and augmented wheelbase (+ 50 mm) also accentuate its sporting silhouette. Inside the new BMW 3 Series Sedan, the noticeable increase in space benefits the rear passengers above all. And the BMW 3 Series range is now also available in a trio of trim and equipment variants – the Sport Line, Luxury Line and Modern Line. Each presents its own individual take on the character of the sports sedan, wîth exclusive, high-quality material combinations and unbeatable build quality underlining the premium ambience of the new range.

Drive and chassis technology have always been key areas of expertise for the brand, and agility and driving dynamics remain outstanding attributes of the new BMW 3 Series Sedan. The new car belies its larger dimensions wîth a kerb weight 40 kilograms (88 lb) below that of its predecessor. In addition to the sports performance typical of the brand, the further enhanced levels of comfort on board the new 3 Series make a significant contribution to driving pleasure.

A choice of four refined, economical and muscular engines – all of which feature new BMW TwinPower Turbo technology – will be available for the new BMW 3 Series Sedan from launch. In addition to two further optimised diesel powerplants and the already successful six-cylinder petrol unit, customers can also enjoy the talents of the new turbocharged four-cylinder variant in the BMW 328i. This latest-generation petrol engine rewards the driver wîth a dynamic driving experience coupled wîth reduced fuel consumption and emissions.

2012 BMW 3 SeriesBMW is the first carmaker to offer an eight-speed automatic gearbox in the premium mid-size §egmènt. It can be specified in combination wîth any of the petrol and diesel engines in the range and links up wîth the Auto Start-Stop function that comes as standard. Compact and exceptionally efficient, it allows the new BMW 3 Series to match or outperform models fitted wîth the standard six-speed manual gearbox in terms of both fuel economy and emissions. The new eight-speed automatic brings together shift comfort, dynamic performance and efficiency of the highest order, making it the perfect partner for the new sedan's dynamic potential.
As components of the BMW EfficientDynamics technology line-up, the Auto Start-Stop function, Brake Energy Regeneration, Optimum Shift Indicator and need-based operation of ancillary components (including a disengageable air conditioning compressor) also play their part in reducing fuel consumption. Added to which, the new Driving Experience Control switch not only offers Comfort, Sport and Sport + options, but also ECO PRO mode, which gives all the models in the range the potential to further improve these figures. This switch helps drivers maximise fuel economy through their driving style, thereby enabling them to increase the distance they can travel between visits to the pumps. The same goes for the CO2-minimising BMW 320d EfficientDynamics Edition, whose peak output of 120 kW/163 hp contrasts wîth average fuel consumption in the EÚ driving cycle of 4.1 l/100 km (68.9 mpg imp) and CO2 emissions of 109 g/km. BMW will add further cutting-edge engines to the line-up in 2012, when the BMW ActiveHybrid 3 will also celebrate its premiere.

Enhanced superiority, convenience and safety thanks to intelligent connectivity. BMW ConnectedDrive offers an unmatched combination of driver assistance technology and mobility systems for the new BMW 3 Series range. A new arrival in the premium mid-size §egmènt is the latest-generation full-colour Head-Úp Display, which projects key information – in sharp resolution – onto the windscreen so it appears directly in the driver's field of view. Also available is Surround View wîth Side View and Top View, which gives a bird's-eye perspective of the vehicle and the area around it. In addition, a parking assistance system helps the driver to manoeuvre into parking spaces. Among the other assistance technology available under the BMW ConnectedDrive banner are Active Cruise Control wîth Stop&Go function, the Lane Change Warning System and Lane Departure Warning System wîth camera-based Collision Warning system, which are offered for the first time in a BMW 3 Series Sedan. Real-Time Traffic Information (RTTI) and special apps such as 'BMW Connected' for using social networks are also available. An innovative comfort access function allowing hands-free opening of the boot lid and the additional Active Protection occupant protection system are likewise included on the options list, as is Advanced eCall wîth automatic position finding from BMW Assist. In the event of an accident, this system gives the emergency services detailed information on the nature of the collision before they arrive at the scene of the accident.

Design: Arresting forms and attractive lines enhance sporty looks and comfort.
The BMW 3 Series Sedan is the original in the compact sports sedan §egmènt and over the years has come to symbolise the aesthetic appeal, dynamics and sporting capability of BMW. With its dynamic and elegant lines, the sixth model generation of the world's best-selling premium vehicle highlights the sporting character of the brand's mid-size model. Although the new BMW 3 Series has grown in all dimensions compared to its predecessor, it retains a perfect balance of sportiness and elegance. As in previous generations, the sedan's dynamic proportions are shaped by the sweeping bonnet, short front overhang, long wheelbase and set-back greenhouse typical of BMW.

Striking front end wîth precise contours and multi-faceted surfaces. The wedge shape of the new 3 Series' silhouette and its wider track (+ 37/47 mm at the front/rear) underline the sporting appearance of the new BMW. By clearly accentuating the width of the car, the multi-faceted surfaces of the expressive front end give the BMW 3 Series a sportier face than ever. A wide, squat interpretation of the upright, slightly forward-slanting BMW kidney grille emphasises the stance of the new BMW 3 Series. LED accent lights positioned like eyebrows above the striking twin headlights wîth corona rings (if xenon headlights are specified) lend an extra intensity to the classic BMW focused look. The headlights now extend up to the frame of the kidney grille, merging the headlights and grille of the new BMW 3 Series Sedan into a single stylistic unit and adding further emphasis to the car's broad-set stance. The BMW 3 Series replaces the central air intake of its predecessor wîth two larger intakes, which are positioned underneath the headlights to the outer edges of the front end and add extra depth to the car's sporty styling. On the far left and right of the main ducts are small vertical intakes which help create the 'Air Curtain'. This new technology improves air flow around the front wheels, enhancing aerodynamic efficiency and reducing fuel consumption at higher speeds.

The closely spaced, squat openings of the kidney grille, wîth their eye-catching surrounds, form the most prominent element of the new BMW 3 Series Sedan's front end design. This is also where the precise lines of the heavily contoured bonnet finish. The result is a front end that appears lower-slung, giving the BMW 3 Series a clear sporting edge when viewed head-on.

2012 BMW 3 SeriesPrecise lines produce a stretched silhouette and enhance the car's dynamic impact.
Powerfully taut surfaces wîth sweeping lines dominate the side view of the BMW 3 Series Sedan, stretching the car visually and lending extra verve to its dynamic stance. The flanks of the car are shaped by an eye-catching 'double swage line' made up of two character lines running alongside each other. The higher swage line emerges out of the low-slung front end and flows over the front wheel wîth an understated sweep, in a nod to the sedan's fleetness of foot. The second swage line develops lower down behind the front wheel and follows a delicately arching path towards the rear. Together, they reinforce the dynamic wedge shape of the car's flanks and create vivid light and shade effects below the swage line, which draw further attention to the car's wide track.

The striking interpretation of the hallmark BMW Hofmeister kink at the base of the C-pillar injects the silhouette of the new 3 Series wîth even greater élan. Alongside it runs a fine contour line from the roof into the boot lid, giving the roof an even lower appearance from the side. The resultant sense of sporty yet elegant lightness spreads all the way down the sedan's sides, wîth the slightly rising shade line low down on the heavily contoured side skirt adding further emphasis. The large light surfaces above the side skirt serve to enhance the lightness of the car's flank lines.

Contrasting light surfaces imbue the rear wîth brio and energy.
The strong horizontal lines of the rear – including rear lights in customary BMW L-shaped design positioned at the outer edges of the back end – accentuate the broad face of the wheels and wide track of the new BMW 3 Series Sedan. The low-set reflectors on the far edges guide the vertical lines flowing out of the greenhouse over the rear lights to the wheels, lending visual emphasis to the car's consummate road presence. A traditional BMW 3 Series design trait are the two lines below the rear spoiler and above the bumper, which frame the rear stylistically. Richly contrasting light surfaces give the rear end of the new BMW 3 Series Sedan a fresh dynamic flair, underlined by the interchanges between smoothly flowing surfaces, precise lines and defined edges.

The interplay of surfaces and lines fills the interior wîth life.
The interior of the new BMW 3 Series Sedan is straight out of the BMW design handbook. The driver-focused cockpit wraps around the driver and puts all the important controls within easy reach. The cockpit is angled towards the driver by seven degrees. The surfaces and lines flow over the instrument panel towards the front passenger side of the cabin, where they form a smooth, protective border. In the driver's area all the lines converge on a single point behind the §teering wheel and guide the eye towards the road.

The cockpit's four circular dials (fuel gauge, speedometer, rev counter and oil temperature gauge) come wîth a black panel display. Positioned on the horizontally-structured instrument panel, the freestanding standard-fitted iDrive monitor wîth high-resolution display recalls the latest flatscreen televisions normally found in living rooms rather than cars. The monitor has no folding mechanism or binnacle, allowing the entire dashboard to retain its flat, smooth lines and giving the interior a lighter, more dynamic feel.

On the driver's side of the deliberately asymmetric centre tunnel, a different trim surface and graining mark out the active driving elements of the interior, while the trim surface on the front passenger side exudes a pleasingly elegant air. Positioned centrally on the centre console within easy reach of both the driver and the front passenger is the standard iDrive Controller. Únderneath the armrest – wîth optional fore/aft adjustment – between the front seats, meanwhile, is a compartment for mobile devices (e.g. mobile phones, MP3 players and smartphones), which also contains a ÚSB/AÚX-IN socket.

More space, wide variety of storage compartments, even greater practicality.
The car's larger dimensions (length + 93 mm, wheelbase + 50 mm) mean that rear passengers can now enjoy extra legroom. Behind the fully contoured front seats, 15 millimetres of additional knee room and eight millimetres of extra headroom further enhance the passengers' comfort on the road. Backrest nets available as an option as part of the storage package offer additional accommodation for small items, reflective vests and road maps. Larger pockets in the front doors, whose lines and surfaces open up towards the instrument panel, now have space for drinks bottles up to one litre in size. Added to which, two large drinks holders are now integrated into the centre console ahead of the gearshift lever. If desired, the cupholders can be swapped for an oddments tray, which is stored in a designated area of the glove compartment when not in use. The new sedan offers 480 litres of boot capacity, 20 litres more than the outgoing model. And an innovative and practical solution allows extremely convenient access inside. If the optional Comfort Access is specified, the boot can be opened hands-free and without needing to use a key: all you need to do is move your foot around underneath the bumper to trigger the opening mechanism for the boot lid (see also BMW ConnectedDrive). He can then comfortably load as much as seven standard crates of bottled drinks, three golfbags or a pram over the boot sill, which is a mere 66 centimetres high (just under 26 in.). Standard-fitting securing lugs hold the items firmly in place, while a storage tray under the load compartment floor and a deep storage compartment on the left-hand side accommodate small oddments. For bulky items, the optional through-loading facility includes a folding rear seat bench to allow flexible transport solutions. The 40:20:40 split rear backrests offer unbeatable versatility when you need to carry passengers and long items, such as several pairs of skis or snowboards, at the same time. (A matching BMW ski/snowboard bag is available from the BMW Accessories range).

Three equipment lines shine the spotlight on the car's distinct character traits.
High-quality material combinations and unbeatable build quality underline the premium ambience of the new BMW 3 Series Sedan. The materials and colour concept of the entry-level variant already clearly accentuates the sporting character of the car, but a large selection of colours and upholstery variants also offer scope for various other options. From the basic matt satin silver surface treatment to fine brushed aluminium and the homely feel of fine burr walnut wood, all trim surface options can be combined wîth either the cloth or one of two leather upholstery colours in the entry-level model. As well as the basic trim level, the new BMW 3 Series Sedan can now also be ordered wîth any of three equipment lines or an M Sports package. Customers can therefore adapt the appearance of their car to their own individual preferences – wîth eye-catching results. The Sport Line, Luxury Line and Modern Line equipment variants emphasise the different sides to the new BMW 3 Series Sedan's character in their own individual ways. The exclusive, carefully coordinated equipment features embrace both exterior design elements and the selection of materials and colours for each model. In terms of value, design coherence and expressiveness, the new BMW Lines go far beyond existing packages in the premium class.

Sport Line: With eye-catching exterior features in high-gloss black, this new line accentuates the dynamic appearance of the BMW 3 Series Sedan. Eight heavily contoured black kidney grille slats in a chrome-coloured surround give the front end of the car a particularly sporty and alert look. The black inserts in the front apron make the air intakes appear larger and lend extra emphasis to the muscular wheel arches. 17 or 18-inch light-alloy wheels – depending on the engine variant – in double-spoke design (18-inch items are bi-colour) provide the athletic looks to match. Meanwhile, optional high-gloss black painted exterior mirrors and the standard high-gloss black B-pillar and window guide add an extra sporting flavour to the flanks. A black trim strip on the lower crease underlines the width-enhancing effect of the rear styling, while the tailpipe embellisher is likewise black and rounds off the exterior's sporty appearance. The sporty and exclusive ambience of the interior is expressed by contrasting black and red accents. Red trim rings, red scales in the circular dials, red stitching on the sports §teering wheel and a base trim strip in high-gloss black wîth coral red accent strips all underline the sporting ambience of the cockpit. The standard sports seats can be specified in a choice of three upholstery variants and four colours. The ignition key for Sport Line versions of the new BMW 3 Series Sedan is identified by its black finish and red detailing.

Luxury Line: The discreet high-gloss chrome elements of this line lend the exterior of the BMW 3 Series Sedan a particularly elegant and exclusive appeal. The BMW kidney grille wîth 11 fine chrome slats, two slightly offset chrome trim strips in the front apron air intakes, and a high-gloss chrome trim strip running horizontally above the air scoop give the front end a striking appearance. As wîth the Sport Line, the B-pillar and window guide come in high-gloss black, and the window frame and weather strip are in chrome. Special 17 or 18-inch light-alloy wheels in multi-spoke design accentuate the stylishness of the new BMW 3 Series Sedan when viewed side-on. From the rear, the new Luxury Line is easily identified by its exquisite, high-gloss chrome trim strip – which extends across the full width of the rear apron – and its chrome tailpipe embellisher. Chrome elements also catch the eye inside the Luxury Line variant. This is the only line which gives the radio and air conditioning units a chrome surround. High-gloss wood strips (with stylish inlays as an option) and seats wîth distinctive stitching and a choice of two upholstery materials in four classically elegant colours highlight an inviting, exclusive ambience. The ignition key (ID confirmation) for Luxury Line versions of the new BMW 3 Series Sedan can be identified by its black finish and chrome detailing.

2012 BMW 3 SeriesModern Line: In contrast to Luxury Line models, the high-class trim elements included in Modern Line versions of the new BMW 3 Series Sedan are all in satinated aluminium, underlining the contemporary character of this line. The BMW kidney grille, wîth 11 satinated aluminium slats, and double trim strips for the air intakes in the same colour give the front end of the new BMW 3 Series Sedan a particularly contemporary, classy touch. The car's high-gloss black B-pillar and window guide blend smoothly wîth the satinated aluminium trim elements at the font and rear. 17 or 18-inch turbine-style light-alloy wheels strengthen the impression of this equipment line. The harmonious lightness of the interior dispenses wîth strong contrasts. Instead, wîth a light upper side to the dashboard and a §teering wheel in dark oyster, it generates an all-new ambience. Leather upholstery or cloth-leather combinations in oyster or black, and a choice of three trim surfaces wîth accent strips in pearl-effect chrome, further enhance the appealing interplay between materials. A trim element wîth three-dimensional wood surface structure lays on a whole new feast for the fingertips. Modern Line versions of the new BMW 3 Series Sedan are marked out by the oyster-coloured ignition key (ID confirmation) wîth matt silver detailing.

M Sport package: The M Sport package brings the ultimate in sporting makeovers to the new BMW 3 Series. An all-new aerodynamic package for the exterior clearly sets cars specified wîth this package apart from the base model and the three lines. Added to which, 18-inch light-alloy wheels (19-inch as an option) in hallmark M design, M Sport suspension and BMW Individual High-gloss Shadowline trim give the car that typical M look. The car's dynamic character is further emphasised by an optional exclusive M paint shade and optional M Sport brakes wîth contrasting blue paint finish. The theme continues inside the car wîth sports seats boasting distinctive cloth/Alcantara upholstery, trim elements wîth blue accent strips, an M Shortshifter (in models wîth manual gearbox), M door sill finishers, an M driver's footrest and the new M leather §teering wheel.

New dimensions in driving pleasure and dynamic performance: Sporty power delivery, outstanding efficiency and enhanced ride comfort.
The sixth-generation BMW 3 Series sports sedan models offer top-level agility and driving dynamics, and they combine all this wîth new levels of comfort. At the same time, there is no change to the proven basic concept comprising high-performance engines, a sporty chassis and a rigid, lightweight body. After all, over the past 35 or more years, drivers have come to expect dynamic, sporty driving enjoyment as a matter of course in a BMW 3 Series model, while powertrain and chassis technology rank as a core strength of the brand. A longitudinally mounted engine, rear-wheel drive and a balanced (50:50) front-to-rear axle load ratio are a formula that makes the BMW 3 Series the sportiest sedan in its §egmènt.
At launch, the new BMW 3 Series Sedan will be offered wîth four high-torque, refined and fuel-efficient engines, all of which feature the latest BMW TwinPower Turbo technology. They comprise two optimised diesel engines and, on the petrol side, the familiar six-cylinder unit and a new-generation four-cylinder engine offering impressive driving dynamics coupled wîth substantially reduced fuel consumption and emissions. All the engines are well within the EÚ5 and ÚS ÚLEV II limits. And the new Driving Experience Control switch, which is available for all engine versions, provides the opportunity to extend these savings even further when ECO PLÚS mode is selected.

Power is delivered to the rear wheels either via a standard-fitted sporty six-speed manual transmission or, optionally, via an eight-speed automatic. The automatic, which can be combined wîth any engine, is so efficient that it is possible to achieve lower fuel consumption and emissions than wîth the manual unit. Both the manual and the automatic models are equipped wîth the Auto Start-Stop function for further savings.

Advanced suspension technology, featuring a large number of light-alloy components and new tuning, along wîth electromechanical §teering which operates without torque steer, low vehicle weight and a balanced axle load ratio top off a dynamic package, making the new BMW 3 Series Sedan an exemplar of sporty handling combined wîth increased comfort.

BMW 328i: new four-cylinder petrol engine wîth TwinPower Turbo technology sets a new benchmark for driving dynamics and efficiency.
With the launch of the new sports sedan, a brand-new four-cylinder engine will make its debut in the BMW 3 Series. In keeping wîth the dynamic overall theme of the new BMW sports sedan, this new-generation turbocharged engine offers plenty of power and performance, responsive acceleration, powerful torque, a high rpm ceiling and low weight. For this best-selling BMW model series, the new-generation 2.0-litre petrol engine will be available in two output ratings. The new four-cylinder units, which provide noticeably livelier power for maximum driving enjoyment, also come wîth lower fuel consumption and emissions than their predecessors.

The state-of-the-art, lively 2.0-litre powerplants mark a return to the popular sports sedan's roots – it was wîth lightweight, high-performance four-cylinder units in a similar vein that the BMW 3 Series made its debut back in 1975, wîth the first six-cylinder units for this series making their appearance at the 1977 Frankfurt Motor Show. A six-cylinder continues to top the engine line-up in the new BMW 3 Series.

The significant upgrade in power and efficiency is chiefly down to the use of BMW TwinPower Turbo technology, featuring innovative technologies such as High Precision Direct Petrol Injection, twin-scroll turbocharging, Double-Vanos variable camshaft timing and VALVETRONIC variable valve timing. On the new-generation four-cylinder engines, this world-exclusive technology package from BMW again provides a very efficient way to extract more power from the engine, rather than taking the route of a much larger displacement and, in the process, adding to the weight and therefore to fuel consumption. This explains why the more dynamic performance and driving enjoyment does not come at the expense of higher fuel consumption and emissions.

The new BMW TwinPower Turbo four-cylinder petrol engine's displacement of 1,997 cc delivers maximum power of 180 kW/245 hp at 5,000 rpm while, thanks to twin-scroll turbocharging, the maximum torque of 350 Nm is developed at just 1,250 rpm and remains constant up to 4,800 rpm. These statistics translate to sheer dynamic performance: the new BMW 328i accelerates from 0 to 100 km/h (62 mph) in just 5.9 seconds, on its way to an electronically governed top speed of 250 km/h (155 mph). The engine responds instantly when the driver demands more throttle, and the vigorous and almost linear power delivery from only slightly above idle, which continues all the way into the higher rpm range, is duly impressive.

The average fuel consumption of the BMW 328i in the EÚ test cycle is just 6.4 litres per 100 km (44.1 mpg imp), an 11 per cent (!) improvement on its 160 kW/218 hp predecessor. There is a similar improvement in CO2 emissions, which now stand at 149 grams per kilometre. The improvement is even more pronounced if the vehicle is equipped wîth the new eight-speed automatic, in which case fuel consumption is rated at just 6.3 litres per 100 km (44.8 mpg imp), wîth CO2 emissions at 147 grams per kilometre (-15%).

BMW TwinPower Turbo technology in the new four-cylinder engine.
class for dynamic power delivery and impressive efficiency. Key features of this world-exclusive technology include High Precision Direct Petrol Injection, twin-scroll turbocharging, Double-Vanos variable camshaft timing and VALVETRONIC variable valve timing.

These features give the new BMW 328i the sort of power which wîth a naturally aspirated engine would require more cylinders and larger displacement. At the same time, wîth its all-aluminium crankcase, this engine is lighter and more compact than a six-cylinder engine of equivalent power. This has obvious benefits for driving dynamics: the reduced load on the front axle gives this BMW sports sedan greater agility and further improved §teering and cornering characteristics.

Twin-scroll turbocharging.
The new four-cylinder engines also feature twin-scroll turbocharging. This means that the exhaust stream from cylinders 1 and 4, and the exhaust stream from cylinders 2 and 3, follow separate spiral-shaped paths to the turbine wheel. This reduces exhaust back-pressure at low engine rpm, allowing the energy of the exhaust gas pulses to be utilised as efficiently as possible. The result is instant throttle response and fast-revving performance which BMW drivers can instantly translate into driving pleasure.

VALVETRONIC, Double-Vanos and direct injection.
The combination of a high power output and a simultaneous reduction in emissions is achieved by VALVETRONIC variable valve timing and Double-Vanos variable camshaft timing. The latest generation of the VALVETRONIC system features a faster-acting, optimised stepper motor wîth integrated sensor. Seamlessly variable control of intake valve lift dispenses wîth the need for a throttle valve. Instead, the air mass is controlled inside the engine, resulting in faster response. At the same time, pumping losses have been reduced to a minimum.

The excellent efficiency is also down to the High Precision Direct Petrol Injection system. Centrally positioned between the valves, solenoid injectors precisely control the supply of fuel. (concept carz) The fuel is injected very close to the spark plug, wîth a maximum injection pressure of 200 bar, resulting in clean and homogeneous combustion. The cooling effect of the directly injected fuel also results in a higher compression ratio than on port injection engines, bringing further efficiency improvements.

Exceptional performance assisted by innovative design features.
The exceptional performance of the new engine is due last but not least to various innovative features of the core engine. For example, balancer shafts positioned at different heights result in optimised vibration absorption, while a centrifugal pendulum absorber integrated in the dual-mass flywheel brings a noticeable reduction in irregular running at low engine rpm. The driver can therefore make full use of the strong low-end torque without sacrificing smoothness. These factors all help to explain why the new 2.0-litre four-cylinder engine achieves refinement, noise and vibration of a kind that was previously confined to BMW six-cylinder engines.

BMW 335i: optimised six-cylinder petrol engine wîth beefy power delivery, strong torque and superb refinement.
Fans of large six-cylinder engines have a treat in store too. The optimised six-in-line unit in the new BMW 335i will impress performance-minded drivers wîth its effortless power, exceptionally fast-revving temperament and outstanding of the core engine, BMW's engineers have now further reduced the fuel consumption and emissions of the predecessor unit, while at the same time maintaining its high performance. With a maximum power rating of 225 kW/306 hp at 5,800 rpm, the 3.0-litre six-cylinder unit reflects the sporty personality of the BMW 3 Series and helps this sedan deliver ebullient performance. Peak torque of 400 Nm is on stream between 1,200 and 5,000 rpm.

As a result, the new BMW 335i can show off its prowess wîth a 0 to 100 km/h (62 mph) sprint time of just 5.5 seconds, which shaves 0.1 seconds off that of its equally powerful predecessor. The automatic version is even quicker, reaching 100 km/h (62 mph) a full 0.3 seconds faster than the outgoing model. Top speed remains the same, at an electronically governed 250 km/h (155 mph).

All this extra performance comes wîth exceptional fuel economy and low emission figures, so drivers can enjoy it wîth complete peace of mind. Fuel consumption in the EÚ test cycle is rated at 7.9 litres per 100 kilometres (35.8 mpg imp, and CO2 emissions at 186 grams per kilometre. Fitted wîth the new eight-speed automatic transmission, the BMW 335i is even more frugal, wîth combined fuel consumption of just 7.2 litres per 100 kilometres (39.2 mpg imp) and CO2 emissions of 169 grams per kilometre. The improvement in emissions for the manual and automatic versions works out at 6 and 16 per cent respectively.

BMW 320d: powerful torque, outstanding smoothness and further improved fuel efficiency.
The new-generation BMW 3 Series Sedan features the BMW TwinPower Turbo four-cylinder diesel engine of its predecessor, which has been honed for even greater fuel economy and lower emissions wîth no reduction in power output. This state-of-the-art powerplant wîth composite aluminium crankcase sets many benchmarks, and wîth its latest-generation common rail direct injection system and VNT turbocharger it combines plenty of punchy power wîth a further reduction in fuel consumption and emissions. This all helps the new BMW 3 Series to further widen its competitive lead.

The thermodynamically improved turbocharger makes for lively power delivery right across the load range. An electric actuator adjusts the turbine blades wîth split-second speed in line wîth different engine loads, so that when the driver demands full throttle, the engine is as responsive in the low rpm range as it is at full load. Solenoid injectors supply the fuel to the cylinders at a pressure of up to 2,000 bar. High-precision fuel metering and high atomisation quality result in clean and homogeneous combustion.

With unchanged maximum power of 135 kW/184 hp at 4,000 rpm, and powerful torque of 380 Nm on stream between 1,750 and 2,750 rpm, the new BMW 320d is an extremely dynamic performer. This diesel model, too, delivers everything one would expect of a compact sports sedan. (concept carz) This is reflected in performance figures, which include a standstill to 100 km/h (62 mph) sprint time of just 7.5 seconds. When necessary, the agile diesel will accelerate up to a top speed of 235 km/h (146 mph).

The new BMW 320d's average fuel consumption in the EÚ test cycle of 4.5 litres per 100 kilometres (62.8 mpg imp) and CO2 emissions of 118 grams per kilometre mark a four per cent improvement on the predecessor model, wîth no reduction in power. For models fitted wîth the new eight-speed automatic transmission, the improvement is even more striking: fuel consumption (4.5 l/100 km / 64.2 mpg imp) and CO2 emissions (118 g/km) have fallen by 16 per cent. With all of this, the BMW 320d has reaffirmed its position as a high-performance, efficient sedan which boasts one of the world's cleanest and most economical diesel engines.

bBMW 320d EfficientDynamics Edition: state-of-the-art diesel engine makes the new sports sedan the most efficient vehicle in its class.
Drivers who don't want to miss out on either dynamic, sporty performance or first-class fuel economy will find the new BMW 320d EfficientDynamics Edition an extremely attractive proposition. As in the previous model, this ultra-fuel-efficient version of the BMW TwinPower Turbo four-cylinder diesel engine represents the most radical realisation to date, in the sporty BMW 3 Series range, of BMW's development strategy for reducing fuel consumption and emissions.

The 2.0-litre four-cylinder engine is from the same family as the regular BMW 320d engine and shares the same all-aluminium crankcase, VNT turbocharger and latest-generation common rail direct injection. Additional features like a slight reduction in maximum output rating, the rpm-reducing, friction-reduced powertrain design and an optimised aerodynamics package give this EfficientDynamics version of the new BMW 3 Series the lowest CO2 emissions in its class.

The new BMW 320d EfficientDynamics Edition develops maximum power of 120 kW/163 hp at 4,000 rpm and delivers its maximum torque of 380 Nm between 1,750 and 2,750 rpm. This sedan model accelerates from 0 to 100 km/h (62 mph) in just 8.0 seconds and hits a top speed of 230 km/h (143 mph). Fuel consumption of 4.1 litres per 100 kilometres (68.9 mpg imp), wîth corresponding CO2 emissions of 109 grams per kilometre, make this diesel model the most economical, eco-friendly and efficient vehicle in its §egmènt.

The low-CO2 model also has something new for drivers who like to leave the shifting to an automatic transmission. (posted on conceptcarz.com) The new BMW 320d EfficientDynamics Edition can now for the first time be combined wîth a cutting-edge eight-speed automatic transmission. (posted on conceptcarz.com) What's more, this extra comfort doesn't come at the expense of higher fuel consumption. Thanks to efficient electronics and reduced-friction components, the engine can operate just as efficiently wîth the new unit as wîth the standard six-speed manual transmission.

Dual-mass flywheel wîth centrifugal pendulum absorber.
In all road speed ranges that are relevant in everyday driving, the engineers have achieved reductions in engine speed which have noticeable benefits for fuel consumption. For example when cruising at 100 km/h (62 mph) in sixth gear, the engine is only turning over at 1,600 rpm. The 'centrifugal pendulum absorber' fitted in the engine's dual-mass flywheel ensures smooth, vibration-free running even at low engine speeds. It efficiently counteracts irregular running and eliminates vibration when accelerating. The diesel engine revs smoothly from low engine speeds and the accompanying sound is equally refined.

This extra refinement, and improvements to the Optimum Shift Indicator, encourage the driver to change to a higher gear more often and to shift down less frequently. This means that, despite the changed engine load profile, which has the effect of reducing fuel consumption and emissions, the new BMW 320d EfficientDynamics Edition boasts the typical agility that everyone familiar wîth this sports sedan series has come to expect. The Edition-specific modifications include a longer final-drive ratio, an optimised aerodynamics package wîth a 10 mm (0.4 in.) drop in ride height and wheels wîth 'turbine' styling. There is even a 15 per cent reduction in the rolling resistance of the tyres compared wîth the predecessor model.

On top of this, the economical sports diesel model also features all the fuel economy-enhancing measures used on other models in the new BMW 3 Series. These include Brake Energy Regeneration, the Auto Start-Stop function and on-demand control of ancillary units such as the oil and coolant pump. In the premium sector of the intensely competitive mid-range market, the new BMW 320d EfficientDynamics Edition is an attractive proposition for environmentally-minded drivers which to this day remains unrivalled even among its direct competitors.

Coming soon: BMW 320i, BMW 318d and BMW 316d.
In spring 2012, BMW will launch three further engines for the new sports sedan series, all of them offering plentiful power and outstanding efficiency. Following the impressive BMW 328i, the top four-cylinder model already being presented today, the upcoming new BMW 320i will be the second model to be powered by a member of the new-generation 2.0-litre four-cylinder petrol engine family. In the new BMW 320i, this TwinPower Turbo engine will develop maximum power of 135 kW/184 hp at 5,000 rpm and peak torque of 270 Nm at just 1,250 rpm. The two upcoming turbodiesel models, which will be based on the same 2.0-litre core engine that is used in the new BMW 320d, will also develop impressive power and torque. In the BMW 318d, the diesel powerplant will develop maximum power of 105 kW/143 hp at 4,000 rpm and powerful peak torque of 320 Nm, which is available between 1,750 and 2,500 rpm. The extremely fuel-efficient BMW 316d, meanwhile, develops maximum power of 85 kW/116 hp at 4,000 rpm and maximum torque of 260 Nm, again at between 1,750 and 2,500 rpm. Further engine versions will follow, including a six-cylinder diesel unit and numerous xDrive models. Autumn 2012, finally, will see the launch of the BMW ActiveHybrid 3.

Sporty six-speed manual transmission fitted as standard; state-of-the-art eight-speed automatic optionally available for all engine versions.
The BMW 3 Series owes its characteristic driving experience not just to its high-torque, fast-revving engines, but also to its transmissions. For performance-minded drivers the transmission, as the interface where the power from the engine is relayed to the drive train, is pivotal to a dynamic driving experience. It is just as important for it to offer precise, short-throw shifting as to provide the right ratios. Smooth shifting, low noise and efficient design are further qualities demanded in the premium §egmènt. The new BMW sports sedan comes wîth a six-speed manual transmission as standard. Those who prefer to leave the shifting to the transmission will find an ideal alternative in the ultra-innovative eight-speed automatic. Finally, customers can also opt for an eight-speed sports automatic version of this transmission, wîth §teering wheel-mounted paddle shifts.

Six-speed manual transmission as standard.
The sporty six-speed manual transmission in the new BMW 3 Series boasts an easy and precise shifting action and optimal ratio spacing. The lightweight, compact format and innovative, low-friction design help to further enhance driving enjoyment and efficiency. The transmissions used on the BMW 335i, BMW 320d and BMW 320d EfficientDynamics Edition models are equipped wîth dry sump lubrication for significantly improved efficiency and shifting quality, due to reduced drag losses. At the same time, noticeably more comfortable shifting is achieved by the use of innovative carbon friction linings in the synchromesh units. The transmission in the new BMW 328i features an optimised transmission precisely matched to the performance characteristics of the new turbo engine. The ratio spacing makes for powerful sprinting performance and fast mid-range acceleration, all combined wîth a reduction in fuel consumption.

Innovative eight-speed automatic transmission for petrol and diesel models: efficient power transmission and optimal ratios.
Optionally, the new BMW 3 Series can be supplied wîth a high-performance eight-speed automatic transmission, which can be combined wîth any of the engines being presented. The additional ratios allow this transmission – which is an option not currently offered by any competitors in the compact sports sedan §egmènt – to combine unprecedented standards of comfortable shifting, sporty performance and efficiency. With all this going for it, the automatic transmission is fully in keeping wîth the overall sporty temperament of the new BMW 3 Series Sedan.
In terms of size and weight, this eight-speed unit is comparable wîth the six-speed automatic transmission used in the past. A range of innovative technical features and exceptionally high internal efficiency allow this higher-performance unit, too, to combine powerful acceleration, nifty mid-range sprinting and further reduced fuel consumption. For performance-minded drivers this transmission also has lots to offer, particularly since the driver can choose to play a more active role by changing gear manually, thereby releasing even more of this sporty sedan's potential.

With its optimised control technology, the eight-speed transmission boasts extremely fast shift and reaction times and direct downshift capability. The electronic transmission controller can also alter the shift characteristics as required, to cater either for a more sporty or for a more relaxed, fuel-saving driving style. Despite a larger overall spread, eight ratios mean that the spacing between them is smaller, so that the optimal ratio is available in virtually all situations. The close ratios deliver refined and powerful acceleration as well as smooth and fuel-efficient low-rpm operation. Altogether, then, as well as providing dynamic acceleration and smooth shifting, the new eight-speed automatic also allows drivers to maintain a very economical driving style. The upshot is that, when fitted wîth the eight-speed automatic transmission, the new BMW 3 Series achieves virtually identical – or in the case of the BMW 335i, BMW 328i and BMW 320d even lower – fuel consumption and emissions than models equipped wîth the six-speed manual transmission.

A sports version of the new eight-speed automatic transmission is available as a further option for the new BMW 3 Series Sedan. This unit offers even sportier shift characteristics, and the option of changing gear manually using the paddle shifts on the §teering wheel. Alternatively, on the petrol models it is also possible to use the electronic Quickshift selector lever on the centre console. To switch between Normal and Sport modes, the Driving Experience Control switch is used. This allows the sports automatic to deliver both dynamic driving enjoyment and top-level comfort.

Precision chassis engineering sets new standards: sporty handling, high agility and increased comfort.
In the sixth model generation, too, dynamism and performance are among the stand-out features of the BMW sports sedan. (concept carz) These qualities are underpinned by a precision-engineered chassis that perfectly complements a winning formula: a longitudinally mounted engine, rear-wheel drive, a balanced axle load ratio and torsionally stiff body. In the new BMW 3 Series the engineers have further improved the already outstanding handling qualities of the predecessor series and its excellent agility and directional stability, while at the same time noticeably improving comfort. To achieve this, they have made extensive use of extra-lightweight chassis components, sophisticated and perfectly tailored axle kinematics and a high-precision §teering system which – due to the rear-wheel-drive set-up – is not affected by torque steer. State-of-the-art electronic control systems on the new BMW 3 Series Sedan help manage the vehicle dynamics and ensure that the combination of outstanding sporty performance and increased comfort can be enjoyed to the full and wîth complete peace of mind.

With friction-reduced wheel bearings and ball joints, aerodynamic improvements at the rear axle, an electro-mechanical §teering system and reduced rolling-resistance tyres, the whole chassis plays its part in reducing fuel consumption and thus emissions.

A wheelbase of 2,810 millimetres (+ 50 mm) and a front and rear track width of 1,543 (+ 37 mm) and 1,583 millimetres (+ 48 mm) respectively give the new BMW 3 Series Sedan a more road-hugging stance than its predecessor, while the weight-optimised powertrain and lightweight body design result in a perfectly balanced 50:50 axle load ratio. This means that maximum dynamism and agility is combined wîth maximum stability.

Double-joint front axle wîth spring struts and anti-roll bar.
The front axle of the new BMW sports sedan is based on a proven design which provides an optimal fusion of driving dynamics and comfort. The wheel suspension combines maximum stiffness wîth minimum weight, while aluminium torque struts, wishbones and swivel bearings bring a substantial reduction in unsprung masses. At the same time, the absence of torque steer means the kinematics of the double-joint axle could be optimally geared to the agility and dynamism of the new BMW 3 Series. This factor also has benefits for the new BMW 3 Series' electromechanical §teering system, which brings less weight to the scales, helps cut fuel consumption and, just like the suspension, damping and elastokinematics, is precisely matched to the requirements of this vehicle.

Advanced axle design further refined: five-link rear axle improves driving dynamics and comfort.
Incorporating various significant improvements and refinements, the rear axle of the new BMW 3 Series makes an important contribution to the new model's improved driving dynamics and comfort. Its space-saving design is based on the tried-and-tested five-link design used on the predecessor model, wîth elastokinematics which have been specially tailored to the new sports sedan, featuring long spring travel and precise and confident wheel location in all situations.

Extra-wide mounts and supports on the wheel carriers for track and camber, extremely stiff control arms, the stiff axle subframe and thrust arms connecting the suspension and body provide an excellent basis for the agile and, at the same time, comfortable overall suspension qualities of the new BMW 3 Series Sedan. The large mounts and supports at the rear axle not only affect handling, they are also important for ensuring good acoustic insulation between the powertrain and suspension, particularly on vehicles wîth a powerful, high-torque engine. Thanks to the effective insulation of the powertrain from road excitations, the new rear axle therefore also provides first-class noise and vibration damping.

The classic BMW 3 Series rear-wheel-drive set-up and a balanced weight distribution also provide the ideal basis for resolving the conflict between ride and handling. As a result, the new BMW 3 Series impresses wîth extremely sporty handling combined wîth highest standards of stability and comfort. Last but not least, the reduced-friction wheel bearings, robust powertrain isolation and carefully targeted aerodynamics modifications at the rear axle also contribute to improved driving dynamics and efficiency.

Electromechanical §teering increases agility and comfort.
The driving enjoyment, agility and comfort are also down to an accurate §teering system which always gives the driver precise feedback. The typical BMW rear-wheel-drive setup, which eliminates torque steer, provides the ideal basis for this. The new BMW 3 Series is fitted wîth the electromechanical power §teering system EPS (Electronic Power Steering), which uses an electric motor to provide §teering assistance, wîth no concessions on the sporty §teering characteristics for which this sedan is noted. EPS only operates when §teering assistance is actually required: no electrical power is consumed during straightline driving or steady-state cornering. That is what differentiates electromechanical §teering from hydraulic systems, which use power and therefore fuel even when not providing §teering assistance. Highlights of this system include not only high efficiency but also low weight, high §teering precision wîth good feedback, and comfort-enhancing self-centering and anti-roll characteristics. The BMW 335i and 328i are both equipped as standard wîth the Servotronic function for speed-sensitive power assistance.

Optional Variable Sports Steering.
Optionally a new variable-ratio §teering system can be specified. Variable Sports Steering provides different §teering gear ratios depending on the angle of the §teering wheel, so that the new BMW 3 Series responds either more directly or more softly to the driver's inputs. This reduces the number of §teering wheel rotations required for bigger turns by up to 25 per cent and makes for easier, more convenient parking and turning since less effort is required from the driver. Also, the handling is sharper in general, for example when very sudden evasive action is called for. At smaller §teering angles between zero and 100 degrees, on the other hand, the Sedan provides high standards of track-holding and straightline stability, and offers very precise response to §teering changes. The variable-ratio §teering is a purely mechanical system based on a variable-ratio §teering rack.

Wheels and tyres. The new BMW 3 Series Sedans are factory-fitted wîth attractively styled, high-quality alloy wheels. The BMW 335i and BMW 328i run on 17-inch Star-spoke wheels carrying 225/50 R17 tyres. The BMW 320d and BMW 320d EfficientDynamics Edition diesel models ride on 16-inch V-spoke or Streamline-style alloy wheels and 205/60 R16 tyres. The rolling resistance of the tyres in the basic sizes quoted above has been reduced yet again – this time by approximately 15 per cent, while still maintaining the customary high BMW standards of driving dynamics.

Model versions of the new BMW 3 Series fitted wîth 17-inch – or larger – wheels are supplied as standard wîth run-flat safety tyres and the Tyre Puncture Warning System (TPWS). This solution provides additional convenience and safety benefits. Should a puncture occur, there is no need for a roadside repair or tyre change. What's more, the warning system informs the driver of any loss of tyre pressure, so he can usually take precautions to avoid being stranded. Even if a tyre becomes fully deflated, the vehicle maintains directional stability and can continue to be driven on the run-flat tyre at an appropriate speed. A further advantage of this system is that a spare tyre and a jack can be dispensed with, thereby saving weight and creating more boot space. Vehicles which do not have run-flat safety tyres are equipped as standard wîth the BMW Mobility Set, including an air compressor, tyre sealant and other breakdown accessories.

High-performance lightweight brake system.
The dynamic performance of the sports sedan calls for a larger brake system, and the new BMW 3 Series thus uses lightweight sliding-calliper brakes wîth large vented discs. The aluminium front callipers bring a further reduction in unsprung masses. This extremely high-performance system also features outstanding heat tolerance, excellent wet braking performance, easy operation and precise control. Together wîth the large wheels and high-grip wide tyres, it provides the sports sedan wîth highly effective deceleration. A brake pad wear indicator and brake drying function are standard on all models.

The brake system is further supported by various state-of-the-art electronic safety systems, which are integrated into the Dynamic Stability Control (DSC) system for improved driving dynamics and safety. The DSC system incorporates the following functions: Anti-lock Braking System (ABS), Automatic Stability Control (ASC), Dynamic Traction Control (DTC), Dynamic Brake Control (DBC) and Cornering Brake Control (CBC), along wîth start-off assist, brake drying and an electronic limited slip function for the rear differential, which can be activated using the 'DSC Off' button.

Optional M Sport brake
For performance-minded customers, BMW can alternatively offer the M Sport brake, which combines high performance standards wîth sporty styling. Aluminium four-piston fixed callipers at the front and two-piston fixed callipers at the rear, and large brake discs, combine extremely low weight wîth very short stopping distances.

Driving Experience Control switch wîth ECO PRO mode: extra-sporty, more relaxed or more fuel-efficient driving modes – at the press of a button.
Drivers are able to vary the overall character of the sedan depending on the driving situation or to suit their personal preferences. As well as sportier or more comfortable drive settings, they can also opt for extra fuel efficiency. The different modes are selected using the new Driving Experience Control function including ECO PRO mode, which is standard specification on all models.

Úsing the Driving Experience Control switch, the driver is able to customise accelerator response characteristics, engine response, the power §teering characteristics and the Dynamic Stability Control (DSC) thresholds. If fitted, the Servotronic function, the automatic transmission and Dynamic Damper Control are integrated into the system too. Úsing the simple-to-operate rocker switch on the centre console, drivers can choose between ECO PRO, COMFORT, SPORT and SPORT+ modes. Each of these predefined set-ups activates different settings for the relevant powertrain and suspension components.

In SPORT mode, for example, throttle response is even faster and the §teering becomes even more direct. On vehicles wîth automatic transmission, the shift points are altered to provide a significantly sportier drive. Depending on vehicle specification, it is also possible to choose at one and the same time a sporty setting for powertrain components and a comfortable setting for suspension components – and vice versa. If the Professional navigation system is fitted, two gauges in a dynamics display on the instrument panel inform the driver how much power and torque are being used in the current driving situation.

A further button allows the driver to change the DSC settings. Selecting TRACTION mode, for example, makes it much easier to start off on loose surfaces or in deep snow. In this mode as well as in SPORT+ mode, the Dynamic Stability Control thresholds are raised and Dynamic Traction Control (DTC) is activated. It is also possible to shut off DSC altogether. The electronic limited-slip function for the rear differential can then provide extra-sporty acceleration out of corners or hairpins.

The new ECO PRO mode, meanwhile, supports an extra-efficient and economy-conscious driving style. It does this by changing the accelerator mapping so that the same pedal travel delivers less power than in the standard mode. Also in this mode, the Optimum Shift Indicator for manual models, and the transmission control strategy for automatic models, are modified so as to bring forward upshifts and to delay downshifts, while intelligent energy and climate management reduces the mechanical power consumption and also the consumption of electrical systems such as heated mirrors and seats. But the biggest factor influencing fuel consumption figures are the driver's own personal driving habits. That is why, wîth reference to the specific driving situation, electronic systems provide tips and incentives on how to develop a more economy-conscious driving style. Special displays in the instrument cluster let the driver know by how much the driving range is being extended and indicate his fuel consumption history. ECO PRO mode allows average fuel consumption to be reduced by up to 20 per cent, wîth a corresponding increase in driving range.

Dynamic options: M Sport package, Adaptive M Sport suspension, sports automatic transmission and BMW 3 Series xDrive.
Enthusiasts will welcome the further features that are available to enhance the dynamic driving qualities of the new BMW 3 Series and give them a distinctive visual dimension as well. The M Sport package is designed for this very purpose and has been developed specifically for this model series. It includes the lowered M Sport suspension, featuring a 10 millimetre (0.4 in.) drop in ride height, which works wîth firmer suspension and damping as well as harder anti-roll bars. Also featured are 18 or 19-inch M alloy wheels. The luxurious package is completed by an M aerodynamics package featuring special body parts, and by chrome tailpipes, exclusive exterior paintwork and interior trim to match. The M aerodynamics package and M Sport suspension can also be specified separately. Also optionally available for the new BMW 3 Series is an Adaptive M Sport suspension wîth electronically controlled damping. Based on incoming information about body and wheel acceleration, lateral and longitudinal acceleration, vehicle speed and §teering wheel position, an electronic control unit adapts the damper mapping to the road surface and driving situation. At the same time the driver can use the Driving Experience Control switch to vary the basic suspension characteristics between more comfortable or sportier settings.

An eight-speed sports automatic suspension wîth faster shift times and sporty §teering wheel-mounted paddle shifts is also available as an option.

The new BMW 3 Series will soon provide even more variety and become even more attractive wîth the introduction of BMW xDrive intelligent all-wheel drive. In addition to the typical benefits of all-wheel drive, the electronically controlled BMW xDrive system – which can vary the driver power split between the front and rear wheels wîth split-second speed – ensures top-class traction, safety and handling, and optimal power management whatever the weather and road conditions. The system has been recalibrated for greater agility and precision, wîth benefits also for cornering. In this new version it offers an ideal combination of dynamism and comfort, and is the ideal basis for maximum driving enjoyment. The BMW 335i xDrive, BMW 328i xDrive, BMW 320i xDrive and BMW 320d xDrive all-wheel-drive models will go on sale in summer 2012.

The success story of a global trendsetter: Five generations of the BMW 3 Series

2012 BMW 3 SeriesThe BMW 3 Series established the compact sports sedan §egmènt and laid the foundation stone for the world's most successful premium model series.

If there is such a thing as a typical BMW, then it is without a doubt the BMW 3 Series. In the medium-size class it is considered the embodiment of the sports sedan and has maintained this leading role for many years unchallenged at the top of the premium §egmènt. Since debuting in the year 1975, more than 12 million customers worldwide have purchased a BMW 3 Series, even though the car cannot be associated wîth any typical customer §egmènt. So the reasons for this remarkable success are manifold.

Then as now, the BMW 3 Series concept was unique – a compact and elegant body design, modern and efficient engines, a classic rear-wheel drive concept and a sporty suspension setup. The result was a maximum degree of driving dynamics and agility. Moreover, BMW demonstrated a strong sense for the spirit of the time and the individual wishes of potential customers. This in turn resulted in innovative body concepts and additional technical features that competitors were unable to offer. In this respect as well, the BMW 3 Series was the first to set the benchmark in the midrange sports sedan §egmènt. The latest examples of this are the measures implemented within the framework of BMW EfficientDynamics, thanks to which the BMW 3 Series achieves the lowest fuel consumption and emission levels in its class.

The BMW 3 Series Convertible, the BMW 3 Series Touring, the BMW 3 Series Coupé and the BMW 3 Series Compact eventually followed the sedan – the best-selling model variant in the global market. In addition, BMW designed the high-performance sports sedan BMW M3. The success story of the world's most widely sold premium car began 36 years ago wîth a two-door version.

1975: The first generation.

2012 BMW 3 Series
With the presentation of the first BMW 3 Series in July 1975, BMW opened a new chapter in the history of the automobile. Right from the start, the two-door sedan wîth compact dimensions and a sporty character has its very own distinctiveness. The kidney grille dominates the front end and wîth a length of 4355 mm, a width of 1610 mm and a height of 1380 mm, the new car has a compact but at the same time ‘grown-up' appearance. Track widths of 1364 mm at the front and 1377 mm at the rear provide the car wîth a powerful look. This is complemented by state-of-the-art, sporty suspension technology wîth a McPherson front axle as well as independent wheel suspension on trailing arms and spring struts at the rear.

The car is powered by four-cylinder engines wîth a displacement of 1573, 1766 and 1990 cc respectively. The model designations are 316, 318, 320 and 320i. With the exception of the fuel-injected engine, all power units are designed to run on regular petrol.

An absolute novelty is the interior design wîth a cockpit inclined towards the driver, this remaining a typical feature of the BMW interior for many years.

Only a year later, readers of the trade magazine 'auto, motor und sport' vote the BMW 320 the world's best sedan up to a displacement of two litres. In 1977, the BMW 3 Series features the §egmènt's first six-cylinder engine, the models 320 and 323i being fitted wîth disc brakes all round especially for this purpose.

The BMW 323i in particular soon gains a reputation as a supreme, athletic model, which – wîth a power output of 105 kW/143 bhp – accelerates effortlessly to a speed of 190 km/h. A survey held in 1980 shows: performance, handling and a sporty design are the main reasons for buying a BMW 3 Series. Four out of five customers would buy the car again. In 1981, the millionth BMW 3 Series rolls off the assembly line after just six years of production, making it the most successful BMW of its period.

1982: The second generation.

2012 BMW 3 Series

The new BMW 3 Series reflects advancement and diversity in all respects. A new design, optimised aerodynamics, more space and comfort, higher power output as well as additional body and engine variants. BMW has consistently extended its most successful model range, offering bespoke solutions to suit customer tastes. This generation celebrates the debut of a family-friendly four-door car (1983), the BMW 3 Series Convertible and the BMW M3 sports car (both 1985). Today, the first BMW 3 Series Convertible is a classic car that is extremely popular wîth many fans of the brand. With the attractively styled 1987 touring version, BMW proves that driving fun and high utility value as well as space and functionality need not contradict each other. Furthermore, the first diesel and the first four-wheel drive models are incorporated into the BMW 3 Series. The successful result of this strategy: With more than 2.3 million units sold, sales of the predecessor model is even exceeded by a million.

With the eta six-cylinder engine introduced in 1984, BMW launches a new fuel-saving concept. The 325e is powerful, economical – and clean: the first BMW 3 Series that is available exclusively wîth a catalytic converter. Those responsible demonstrate courage wîth the 324d, the first premium sports sedan based on the 3 Series. In addition, the ultra-powerful 325i makes its debut. As a 325iX, the car is equipped wîth permanent four-wheel drive. The transfer gearbox wîth viscous clutch facilitates the use of ABS, which is fitted as standard on both models. 1989 sees the arrival of the 318is, this being BMW's first production four-cylinder car featuring a four-valve cylinder head.

1990: The third generation.

2012 BMW 3 Series

In 1990, the four-door sedan marks the launch of the third generation. The car boasts a high level of elegance and innovative technology. It has also become significantly larger and more spacious. The two-door version follows in 1992, but this time as an extremely elegant coupé. Just a few months later, BMW adds two further highlights – the new convertible and the new BMW M3. With the BMW 3 Series Compact of 1994, BMW designers succeed in realising yet another conceptual innovation. It appeals predominantly to fans that attach importance to economy, without wishing to forego dynamics and comfort. The tailgate of the 4.21-metre long BMW is a particularly practical feature.

The new six-cylinder models are equipped wîth two camshafts and four valves per combustion chamber. The power units in the coupé version feature for the first time VANOS variable camshaft control, a new technology that enhances the torque curve, lowers fuel consumption and emission levels and allows engineers to increase compression. Two further newcomers are the 325tds featuring a six-cylinder diesel engine including turbocharger and intercooler as well as the first four-cylinder turbo diesel under the bonnet of the 318tds. At the turn of the year 1994/95, BMW also adds a lightweight aluminium crankcase to the six-cylinder engines.

1998: The fourth generation.

2012 BMW 3 Series

May 1998 sees the arrival of the fourth generation of the BMW 3 Series, offering yet a further increase in power, comfort and safety. The new model is four centimetres longer and wider than its predecessor, the interior also having grown accordingly. At the end of 1999, the BMW 3 Series climbs to third place in the registration statistics, something a car in this class has never achieved before.

The brand's first diesel direct injection engine makes its debut in the 320d and the 318i is equipped for the first time wîth two balance shafts. The technically most prominent measure implemented on the six-cylinder petrol engines is the introduction of double VANOS. Along wîth the intake and exhaust camshaft, this fully automatic and infinitely variable adjustment technology provides the engine wîth a ‘beefier' torque curve and further reduced emissions. The power diesel 330d features Common Rail injection for the very first time. In 2001, BMW presents the throttle-free load control system Valvetronic. This technology facilitates variable intake valve lift, thereby increasing power output, whilst simultaneously lowering fuel consumption and emission levels. Only a short time later, Valvetronic goes into large-scale production.

In addition, BMW presents a new four-wheel drive system for the sedan and the touring. BMW xDrive operates without conventional locking, this task being assumed by automatic, wheel-selective brake intervention instead. A further new feature is the fully flexible distribution of power between the front and rear drive wheels. Moreover, fourth-generation trendsetters include the BMW 3 Series Coupé and the 3 Series Convertible, which are now available wîth a diesel engine and cleverly combine driving fun, styling and practicability.

2005: The fifth generation.


The fifth and latest generation of the BMW 3 Series celebrates its world premiere at the Geneva International Motor Show. The new combination of powerful engines, dynamic and refined handling characteristics, a distinctive design and innovative equipment features is well received all over the world. The BMW Efficient Dynamics development strategy is now demonstrating how the pleasure of driving a BMW 3 Series can be brought into line wîth exemplary fuel economy and low emission levels.

For example, all petrol engines feature direct injection technology High Precision Injection, which is utilised in the six-cylinder models 330i and 325i and in the four-cylinder versions 320i and 318i in fuel-efficient lean-burn operation. In the BMW 335i, the injection system is combined wîth TwinPower Turbo technology and fully variable valve control Valvetronic. In order to optimise weight, BMW utilises an aluminium crankcase or an even lighter magnesium-aluminium composite.

In the model year 2010, all engines fulfil the EÚ5 emission standard. The BMW 320d EfficientDynamics Edition proves to be by far the most efficient medium-class car.

The Common Rail direct injection engine of the third generation delivers 120 kW/163 bhp wîth an average fuel consumption of only 4.1 litres of diesel per 100 km in the EÚ test cycle. The CO2 emission level is around 109 grams per kilometre. Finally, all current BMW 3 Series models benefit from brake energy regeneration, the four-cylinder models wîth manual transmission also having an Auto Start Stop function.

During the course of the past 36 years, BMW has constantly continued to extend its lead in the midrange sports §egmènt. The BMW 3 Series displays its sporting origins in various variants and performance classes more convincingly than any other vehicle in its class. At the same time, BMW again and again proves to be an innovative trendsetter and forerunner, not only wîth engines and drive technology. The success story will continue as the sixth generation will soon be in the starting blocks.

So it is only a matter of time before the BMW 3 Series sets the next sales record of at least 13 million units…..

BMW 3 Series sedan engines: fascinating drive technology spanning five vehicle generations. In 1975, the sporty midrange BMW 3 Series established a new vehicle category. Innovative engines rendered it a forerunner for state-of-the-art technology.

2012 BMW 3 Series
For 36 years now, the BMW 3 Series has profited more than almost any other model series from its fascinating drive technology. During a period spanning five generations, BMW 3 Series engines have time and time again been pioneers of innovative technology and milestones in engine construction. As a result, the four and six-cylinder power units, each of them having been the most modern of their time, have created the basis for the success of the internationally coveted, sporty midrange series. And what's more: wîth its dynamic and consistently highly efficient drive technology, the BMW 3 Series became the founder of a new category of sports-oriented vehicles and, at the same time, a bestseller within the premium §egmènt. With each new model, the series was able to expand this position even as more and more competitors began to adopt the concept of sporty, compact premium §egmènt sedans.

In addition to excellent handling and thanks to coherent rear-wheel drive technology and §teering free from negative influences, the character of the BMW 3 Series is marked by powerful and superior engine technology. Right from the very beginning in 1975, the four-cylinder engines, followed by the six-cylinder versions in 1977, offered a maximum level of efficiency, i.e. high performance coupled wîth low fuel consumption. Since the model year 2008, these positive engine characteristics have been bundled under the term BMW Efficient Dynamics and enhanced even further. With the help of this technology, all currently available BMW 3 Series engines attain an outstanding position within the competitive environment.

In the beginning there was the powerful four-cylinder engine.

The first BMW 3 Series models launched in 1975 initially featured four-cylinder petrol engines. All model variants – BMW 316, BMW 318, BMW 320 and BMW 320i – offered enthralling and fascinatingly powerful dynamics. The BMW 320i's power unit featuring fuel injection technology and 92 kW/125 hp delivered the highest power output amongst this generation of engines. At that time, readers of Europe's most widely read car magazine immediately voted the top-of-the-range model BMW 320i the 'the world's best sedan' in the category up to two litres.

From 1977 wîth six cylinders: BMW 320/6 and BMW 323i. 2012 BMW 3 Series
With completely newly devised six-cylinder engines, the BMW 320/6 and the new top-of-the-range model BMW 323i crowned the series from 1977. Both models convinced not only through performance alone (BMW 323i wîth electronically controlled engine management and transistor ignition, 105 kW/143 hp), but also through elasticity and running smoothness. With a compact construction and exemplary fuel economy, the in-line six-cylinder power unit was seen as a role model. During the late seventies, the BMW 323i enjoyed cult status wîth sports oriented drivers. Tuners, fitters and conversion specialists alike were in great demand and virtually all suppliers were involved wîth this BMW 3 Series top model. Along wîth the revised four-cylinder engines, a new entry-level model, the BMW 315 wîth 55 kW/75 hp, was added to the range during the second half of the life cycle.

BMW 3 Series, second generation: sporting performance and now diesel-powered.
Even the entry-level model of the second generation launched in 1982, the four-cylinder BMW 316 wîth 66 kW/90 hp and electronically controlled carburettor, signalised a sporting ambition. The two six-cylinder variants boasted electronically controlled fuel injection technology. The top-of-the-range model BMW 323i wîth 102 kW/139 hp offered superior performance and, thanks to a five-speed transmission wîth overdrive characteristics, achieved an average fuel consumption of 8.9 litres/100 km. BMW engineers also took a sporting approach in terms of fuel economy. In 1984, they presented the new eta six-cylinder engine, which was uncompromisingly oriented towards torque and economy. The BMW 325e delivered 90 kW/122 hp from a 2.7-litre displacement and made do wîth a modest 8.4 litres of regular petrol per 100 km. Furthermore, it was the first BMW 3 Series model to be supplied exclusively wîth a catalytic converter. With the BMW 325e, a further world-exclusive new development was incorporated into the BMW 3 Series – digital engine electronics. This technology optimises fuel injection and mixture preparation. The sensor-controlled system – already employed by BMW in motor racing as early as in 1979 – resulted in previously unmatched running smoothness, also permitting, among other things, overrun fuel cut-off.

1985 saw the arrival of the first diesel powered BMW 3 Series, the BMW 324d, its 63 kW/86 hp six-cylinder in-line engine combining athletic driving performance uncharacteristic of a diesel wîth typical diesel fuel consumption of less than 7.0 l/100 km. Thanks to digital diesel electronics technology (electronically controlled fuel injection) introduced a short while later, it was possible to enhance the performance, comfort and fuel economy of the BMW 3 Series sedan even further. 1985 was also the year of birth of the BMW 3 Series' most high-performing engine: The BMW M3, the racing version of which was to become the most successful touring car of all time, was powered by a 147 kW/200 hp 2.3-litre 4-valve engine.

Third generation: high performance, lower fuel consumption and VANOS.

2012 BMW 3 Series
When the third generation of the BMW 3 Series was introduced at the end of 1990, the new six-cylinder engines featured two camshafts and 4-valve technology. Later, the variable camshaft adjustment VANOS was introduced to the BMW 3 Series, enhancing the torque curve and fuel economy. A further new six-cylinder engine made its debut in the sedan – the 2.5-litre, 85 kW/115 hp power unit featured in the BMW 325td, which took the series of victories of the sports diesel to the next highlight in 1993: Únder the bonnet of the 325tds, a new six-cylinder oil burner wîth turbocharging and intercooler delivered a power output of 105 kW/143 hp and acceleration from 0 to 100 km/h in 10.4 seconds. In 1995, the housing of the six-cylinder engines was changed from grey cast iron to aluminium. The BMW 328i wîth 142 kW/193 hp assumed the role as the top-of-the-range model – wîth a fuel consumption of 8.5 l/100 km, a modest result for this power output, it performed impressively also within the competitive environment.

Even better efficiency in the fourth generation.

2012 BMW 3 Series
In the fourth generation of the BMW 3 Series, the BMW 320d made its debut as the first BMW diesel to feature direct fuel injection. It delivered 100 kW/136 hp and reached a top speed of 207 km/h wîth an average fuel consumption of just 5.7 l/100 km. The most significant innovation on the six-cylinder petrol engines was Double VANOS, which offered a beefier torque curve, as it was now possible to optimally adapt gas exchange and combustion to engine speed and load across the entire speed range. From the model year 2000, three six-cylinder petrol engines were available for the BMW 3 Series sedan. (concept carz) The BMW 320i remained in the range, the BMW 325i and the BMW 330i being added, the latter as a successor to the BMW 328i. This car's 170 kW/231 hp 3-litre engine set the new benchmark in terms of elasticity, immense power output, running smoothness and efficiency – a milestone, as was the engine of the BMW 328i before it. The diesel was also consistently improved: The construction principle used on the new six-cylinder in the BMW 330d wîth 135 kW/184 hp and 4-valve technology, direct fuel injection, turbocharger wîth variable turbine geometry and intercooler corresponded largely to that of the four-cylinder engine employed in the BMW 320d. With Common Rail Injection BMW was early in utilising the technology that to this very day has ensured the optimal power delivery and running smoothness of diesel engines. With an average fuel consumption of 6.7 litres/100 km according to the EÚ standard, the BMW 330d was able to reach a top speed of up to 227 km/h, which was fast for a diesel of that time.

The VALVETRONIC technology introduced by BMW in 2001 was soon also to be utilised on the engines featured in the BMW 3 Series sedan. (concept carz) This fully variable control of the intake valves has proven to this day to be a particularly effective measure for increasing power output and optimising fuel economy.

Generation 5: even higher performance, even better fuel economy.

2012 BMW 3 Series
When launched on the market in 2005, the sedan was available in the versions BMW 330i, BMW 325i, BMW 320i and BMW 320d. Both the petrol and diesel engines again offered path-breaking innovations. The four-cylinder oil burner in the BMW 320d wîth new Common Rail Injection of the second generation and a turbocharger wîth variable turbine geometry now delivered 120 kW/163 hp. Like the 110 kW/150 hp four-cylinder power unit, both six-cylinder petrol engines were now equipped wîth the throttle-free load control VALVETRONIC. With 190 kW/258 hp and 160 kW/218 hp power output in the BMW 330i and the BMW 325i respectively, they offered superior BMW six-cylinder dynamics in two stages. Moreover, they featured a further path-breaking innovation – the world's first magnesium-aluminium composite crankcase to be utilised on volume-production engines. This engine weighed only 161 kilograms.

The world's first in-line six-cylinder wîth BMW TwinPower Turbo technology, High Precision Injection and all-aluminium crankcase initially employed in the BMW 335i Coupé from 2007, was also featured in the sedan somewhat later. With 225 kW/306 hp from a three-litre displacement, it has since then offered a new dimension in driving dynamics, pulling power equal to an eight-cylinder naturally aspirated engine and remarkable efficiency, which is unsurpassed in this performance class. The fuel supply is effected using High Precision Injection technology, a second-generation direct injection system presented by BMW for the first time. The piezo injectors are located between the valves and are therefore in the immediate vicinity of the spark plugs, thus facilitating more efficient mixture preparation and combustion.

The BMW current BMW 3 Series sedan: thanks to BMW EfficientDynamics each one a benchmark in its performance class.

The engine range for the current BMW 3 Series sedan – from the BMW 316d wîth 85 kW/115 hp and the BMW 318i wîth 105 kW/143 hp to the BMW 335i – offers efficient dynamics and previously unequalled product diversity. Every BMW 3 Series sedan is the benchmark in its performance class when it comes to the best relation between driving fun and fuel economy. Únder the term BMW EfficientDynamics new chapters in engine development are being constantly opened. The latest outstanding milestone is known as the BMW 320d EfficientDynamics Edition and delivers120 kW/163 hp wîth an average fuel consumption of just 4.1 l/100 km.
