2007 BMW 335i Coupe

Introducing the latest expression of individual style - the all-new BMW 3 Series Coupe. With totally new looks, the newest BMW Coupe once again sets the benchmark for elegant design, luxury and value. In true BMW tradition, it also establishes a new standard of performance and driving dynamics with the introduction of an exceptional engine: the first inline six-cylinder with twin-turbochargers, high-precision fuel injection, and an all-aluminum crankcase.

The performance potential of this new 300 horsepower engine ensures that the 335i Coupe offers a significant improvement in performance while maintaining a level of efficiency for which the BMW 3 Series is renowned.

In addition to the standard six-speed manual, both models will be offered with an available six-speed STEPTRONIC automatic transmission. (posted on conceptcarz.com) Designed for responsiveness, the new automatic enhances driving dynamics without sacrificing fuel efficiency.

An additional dimension of driving dynamics, with the benefit of outstanding traction, will be offered with the introduction of BMW's xDrive all-wheel drive. BMW xDrive is the most sophisticated and responsive all-wheel drive system on the market. It has proven its merits, in terms of agility and safety, in the ten models currently offered with xDrive in the Ú.S. Beginning this fall these merits will become available to Coupe drivers for the first time.

The premium character of the newest BMW Coupe is recognizable from the very first glance. Over and above the basic shape of the car and its elegant lines, the graphic design of the headlights, the detail of the rear taillights, the interior and even the exterior mirrors were specifically crafted for the new Coupe. These unique design elements reflect the unique character of this elegant and sporty new car.

The buyer who chooses a Coupe wants a car that satisfies their demand for elegant looks as well as driving dynamics. With all this in mind, BMW engineers and designers set out to create a unique yet unmistakable blend of design, features and - most particularly - driving pleasure.


Designed to reflect performance and elegance in the tradition of BMW Coupes

The new Coupe is unquestionably a BMW 3 Series. Yet despite its close technical ties to the Sedan and Sports Wagon, the new BMW 3 Series Coupe is unique in its design details. A genuine BMW from every angle, the new Coupe is an individualist through and through.

The character of any coupe is reflected in its profile. On the new BMW 3 Series Coupe the profile is unmistakably BMW. The long hood reflects BMW's adherence to its tradition of inline six-cylinder engines. The long wheelbase, the passenger compartment set back as well as the low, sleek roofline which slopes gently into the trunk, are all characteristic of BMW Coupes.


In addition to the classic proportions, the shoulder, character and sill lines serve to enhance the sleek appearance. Both the shoulder line and character line stretch uninterrupted to the back of the car, allowing one's eye to move quickly and smoothly from front to rear along the entire length of the car. The sill line on the lower edge of the door also flows into the front and rear air dams, reinforcing the dynamic nature of BMW's newest Coupe.

The combination of lines flowing into one another reflects the performance potential. While the shoulder line rises slightly but consistently from front to rear, the character line flows in a long, stretched arch all the way from the front fender to the taillights. As the sill line, by contrast, moves up slightly to the rear in a slow and gentle curve, the distance between the character and sill lines becomes smaller around the rear wheel arches. The flare of the fender around the wheel also serves to give the character line extra tension in both an upward and outward direction.

The front view also shows a significant distinction from the 3 Series Sedan and Sports Wagon. The contours of the hood as well as the design of the front air dam and headlights give the new BMW 3 Series Coupe a particularly low and sporty look. The powerdome on the hood foretells the performance potential which lies beneath. Its lines follow a powerful silhouette extending all the way from the A-pillars to the outside corners of the BMW kidney grill.

The kidney grille, a typical feature of every BMW, stands out from the surfaces around it. Interaction with the three-dimensional kidney frame creates a look of power and unique style.

The headlight units on the new BMW 3 Series Coupe also have a unique look. With the hood extending beyond the headlights as such, the characteristic four round headlights appear to have been cut-off at the top creating a sense of powerful, concentrated focus.

The new 3 Series Coupe will come standard in the Ú.S. with xenon adaptive headlights, accented by BMW's corona light rings. The corona light rings not only serve as daytime running lights, but also draw attention to BMW's characteristic four round headlights, making this new Coupe instantly recognizable as a BMW, day or night.

The design of taillights is also unique to the new 3 Series Coupe. Integrated flush into the body of the car, the lights are split into two sections and extend all the way up to the trunk lid, blending with the character lines from the side profile. Horizontal LED taillights give the car an unmistakable look at night. The horizontally flowing lines accentuate the wide track and low stance of the new Coupe.

The designers' objective was to give the new 3 Series Coupe a balanced and harmonious look. The traditional 'Hofmeister kink' at the bottom edge of the C-pillar now extends at an even more distinct angle into the shoulder line. To further accentuate this flow of lines, the window accent surround is now made in one single piece.

The exterior mirrors have been specifically designed and matched to the unique character of the new 3 Series Coupe. The contours of the mirrors reflect the profile lines while the mirrors blend seamlessly with the car's overall design.

The emphasis on individual style, dynamic performance and exclusivity continues within the interior. Horizontal lines dominate the surfaces on and around the instrument panel which blend with the lines of the center console and door panels to give the interior a light but dynamic feel. In true BMW fashion the instrument cluster and key controls are angled toward the driver. Controls for the climate control as well as the audio and navigation systems are within easy reach of the front passenger. Given that the new Coupe is a four passenger car, the rear seat passengers are treated to a storage compartment between the rear seats.


An elegant ambience is created in the interior by special lighting and switches with a premium look and feel. The light contour edge on the door and side panels, which runs from the door pillar all the way to the rear passenger area, creates a particularly warm, indirect lighting effect. Controls and switches used frequently by the driver and passengers such as the door handles and gearshift are finished in high quality metallic trim for an elegant appearance as well as a premium tactile experience.

Inline six-cylinder engines enter new dimensions of performance.

The first impression the new BMW 3 Series Coupe delivers is one of stylish elegance and powerful dynamics. Its long hood reflects BMW's longstanding tradition of inline six-cylinder engines.

The new BMW 3 Series Coupe will arrive in the Ú.S. with a choice of two six-cylinder engines including the world's first inline six with twin turbos, high precision fuel injection, and an all-aluminum crankcase. It is the most powerful engine within BMW's wide range of inline six driving machines that does not wear an 'M' badge. This brand-new version develops maximum output of 300 hp in ÚS-spec from 3.0 liters and generates peak torque of 300 lb-ft for powerful acceleration in any situation.

The combination of turbocharging and direct gasoline fuel injection offers a new dimension to efficient dynamics. Featuring high-precision fuel injection, the engine boasts a highly sophisticated and advanced direct fuel injection system. In true BMW fashion this results in outstanding performance combined with a significant reduction of fuel consumption.

A further advantage of turbocharging is that this is the most economical option to boost engine power and performance. For example, the turbocharged inline six weighs approximately 150 lbs less than an equally powerful eight-cylinder displacing 4.0 liters. And this lower weight means a significant advantage not only in fuel economy, but also in balancing the weight distribution of the overall car.

This new high-performance engine gives the light, aerodynamically sculpted Coupe truly outstanding acceleration and flexibility on the road. The twin turbo powerplant in the BMW 335i Coupe develops its power and performance much more spontaneously than a turbocharged engine of conventional design. Thanks to their lower inertia, the two small turbochargers build up pressure much faster than a single, large turbocharger, thus eliminating even the slightest turbo 'lag'.

At the same time the new engine offers all the smoothness and refinement which has made BMW's award-winning inline sixes so admired. Last but certainly not least, the impressive increase in power on the twin turbo engine versus a conventional normally aspirated six-cylinder comes without any significant increase in fuel consumption.

Featuring two turbochargers each supplying compressed air to three cylinders, the new turbocharged engine offers a new standard of spontaneity and responsiveness. Peak torque of 300 lb-ft comes smoothly and without delay, extending over a wide speed range from 1,400 - 5,000 rpm.

On the road, this power and torque result in outstanding performance. The 335i Coupe accelerates from 0 - 60 mph in just 5.3 seconds. This sense of urgency continues all the way to the electronically-limited top speed of 150 mph, when equipped with sport package.

This extremely efficient increase in power and performance is attributable in large part to gasoline direct injection. The high-precision fuel injection concept developed by BMW ensures a measurable advantage in fuel economy, without limiting the dynamic qualities of the engine.

To enhance this efficiency to an even higher level, the turbochargers are made of a particularly heat-resistant material which makes them immune to high exhaust gas temperatures in the interest of a fuel-efficient combustion process particularly under full load. As a result, the twin turbo technology in the BMW 335i Coupe represents a significant achievement in terms of both performance and fuel economy. The advantages over a conventional turbocharged engine are not only clearly measurable, but also easy to feel on the road.

The new six-speed STEPTRONIC automatic uses an innovative torque converter and enhanced management software to improve shifting responsiveness. The response time of the automatic transmission on the new BMW 3 Series Coupe is down by approximately 40 per cent compared with a conventional automatic transmission. (posted on conceptcarz.com) While fast, responsive gear changes can make driving more fun, the optimized selection of the appropriate gear for all driving conditions helps to reduce fuel consumption. This new automatic is a textbook example of BMW's pursuit of Efficient Dynamics.

Chassis and suspension: where power becomes performance.

Even with great looks and outstanding performance, it would not be a BMW Coupe if it did not also offer equally outstanding handling and responsiveness.

The new 3 Series Coupe offers class-leading agility through a combination of significantly enhanced dynamic potential on one hand, with the most sophisticated chassis control and assistance systems on the other. Together they provide a margin of safety for any situation in which the car might reach the limits of driving physics. In other words, the driver and passengers in a BMW 3 Series Coupe enjoy superior safety at all speeds.

Traditional rear-wheel drive and a near 50:50 front-to-rear weight distribution give the new BMW 3 Series Coupe ideal qualities for optimum driving dynamics. This, in combination with the high-tech suspension, enables the driver to convert the power and performance of the engine into an exhilarating driving experience. Boasting a double-pivot front suspension with spring struts made almost entirely of aluminum in combination with a five-link suspension at the rear, the new BMW 3 Series Coupe has the most advanced and sophisticated suspension in its class.

Reinforcement and support elements on the underfloor of the car serve to optimize the stiffness of the chassis which enables the suspension to work with the highest possible degree of precision. Interacting with the low centre of gravity and the specific set-up of the shock absorbers, the chassis and suspension work in perfect balance.

BMW's rack-and-pinion steering has been widely praised for its precision and feedback and the steering in the new 3 Series Coupe is no exception. For the ultimate balance between agility at lower speeds and stability at higher speeds, BMW's innovative Active Steering will be available. By adjusting the steering ratio, steering angle and power assistance to the speed of the car, Active Steering enables the driver to maneuver the 3 Series Coupe with minimum effort when parking and keep the car precisely on track at higher speeds.

The high-performance brake system requires 17-inch wheels to match the larger diameter of the brake discs which ensure outstanding stopping power and deceleration. Brake performance is further enhanced by BMW's latest Dynamic Stability Control. Introduced on the 3 Series Sedan, BMW's latest DSC incorporates several new functions. For example, DSC works to counteract the slightest brake fading effect even at extremely high brake temperatures by increasing brake pressure accordingly. This ensures maximum brake power even under the toughest conditions, without requiring the driver to exert any higher pressure.

Brake Standby positions the brakes closer to the discs after sudden lift off of the accelerator pedal to further reduce stopping distances in an emergency. Dry Braking, in turn, optimizes brake performance in the wet by using the brake pads to periodically dry the brake discs. Dynamic Brake Control automatically maximizes brake pressure whenever required in an emergency stop. Start-Off Assistant briefly holds the car when setting off on an uphill grade.

In a 3 Series Coupe equipped with Active Steering, DSC helps keep the car stable and under control when applying the brakes on surfaces varying in their frictional coefficient. DSC corrects the steering quickly and precisely for optimum control.

Dynamic Traction Control is another feature of DSC. Activation of DTC raises the threshold for intervention by the brakes, enabling the driver of a BMW 3 Series Coupe to set off smoothly on low friction surfaces such as snow. A benefit of DTC for the enthusiast is that it allows slight, easily controllable slip on the drive wheels even on a dry surface.

Of course, as in all BMWs, the driver also has the option to completely deactivate DSC in the new 3 Series Coupe.

BMW's intelligent xDrive all-wheel-drive system will be available as an alternative to rear-wheel drive for those who need an extra measure of traction with BMW responsiveness. Acknowledged as the most sophisticated and responsive of all-wheel drive systems, BMW xDrive allows the new 3 Series Coupe driver to enjoy the ultimate driving experience in all types of weather and driving. xDrive not only distributes power to each of the four wheels as road conditions require, it partners with DSC to play an active role in helping to stabilize the vehicle at the onset of oversteer or understeer. It will be available this fall in the 328xi Coupe.

The new BMW 3 Series Coupe comes standard with runflat tires for both models. Featuring the most advanced failsafe running qualities, these tires allow the driver to continue for up to 150 miles even under complete loss of pressure. The standard Tire Pressure Monitor gives plenty of warning and alerts the driver when the pressure of any tire falls 30 percent below the ideal level.

Últra-modern body structure: lower weight, greater safety, improved responsiveness.

The new BMW 3 Series Coupe is light, strong and stable at once. Its structure is tailored to improve agility, safety and comfort while also contributing to overall vehicle efficiency.

Low vehicle weight and a high standard of torsional body stiffness is also crucial to the car's agility. In the event of a collision, the use of high-strength steel in critical areas, together with the exactly defined deformation zones, ensures effective absorption and, respectively, transfer of forces acting on the body of the car.

Reinforced B-pillars are a particularly impressive example of the high standard of development and excellence in design that the new BMW 3 Series Coupe has achieved, with a tubular structure throughout the B-pillars featured for the first time for added strength. This tubular reinforcement is made of ultra-strong steel in a warm-molding process and is heat-treated for top quality while still in the mold. The reinforcement tube is variably contoured in its cross-section, exactly matching the space available. Together with the crash box tailored to the loads, which act on the body, this ensures maximum safety.

The choice of materials and the arrangement of components at other points on the body also serve to optimize crash safety. The various properties of different types of steel and other materials are used to best effect. The space available for deformation on the new BMW 3 Series Coupe is used to minimize even the slightest impairment of the passenger cell. In a head-on collision, for example, dynamic deformation areas at the front keep impact energy away from the bulkhead and, accordingly, from the car's footwells. In the event of a side-impact collision, the specially designed floor assembly ensures controlled transfer of forces acting on the car to the opposite side of the body.

The bulkhead support is made of innovative multi-phase steel offering outstanding strength and stability even on thin-gauge panels. Efficient interaction of the doors, the reinforced b-pillars, the seat structure and the instrument panel between the A-pillars serves likewise to maximize the strength of the side structure. The consequences of a collision from the rear are minimized by longitudinal carrier bars, a wide range of reinforcement elements, as well as the extra-strong luggage compartment floor panel, rear panel and side walls. Stable pillars and crossbars also help protect the passenger area in a rollover.

Naturally, BMW's safety engineers sought from the start to fully maintain the passenger cell as a safe environment even in the most severe crash impact. Centrally masterminded restraint and support systems within the passenger compartment ensure individual occupant safety tailored for any contingency. The frontal, hip, side airbags along with curtain-type Head Protection System, belt latch tensioners and belt force limiters are activated by sensor-controlled electronic safety systems as a function of the type and severity of a collision. With its robust body enhanced by a wide range of active and passive safety features, the new BMW 3 Series Coupe meets all requirements for optimum results in all crash tests.

With active driving calling for optimum visibility at night, the new BMW 3 Series Coupe comes standard in the Ú.S. with xenon adaptive headlights. Light rods in the rear light clusters stand out distinctly for a significant improvement of safety in the dark.

Whether in the dark or during the day, two-stage adaptive brake lights make an important contribution in enabling following drivers to recognize a dangerous situation well in advance. Whenever the driver applies the brakes particularly hard, and when the ABS function is activated, light intensity in the two-stage taillights is increased accordingly, prompting drivers following from behind to brake harder, too.

Impressive standard and optional equipment.

The list of comfort features boasted as standard equipment in the new BMW 3 Series Coupe is just as long and impressive as the list of safety elements. Particularly in the area of top-quality audio, navigation and telematic solutions, BMW offers optional high-tech concepts originally developed for the most outstanding luxury performance cars.

Here again, the focus is on the actual driving experience. The seating position at the rear is lower than in the Sedan, for example, gives the car's occupants optimum headroom despite the low roof line of the Coupe. At the same time not only the driver and front passenger, but also the rear passengers will immediately feel and enjoy excellent side support.

The door handle trim, gearshift lever cover and vent grille adjusters, as well as the decorative trim in the leather sports steering wheel all come in Pearl Gray chrome surface finish developed exclusively for the new BMW 3 Series Coupe. The starter button is also finished in this material.

Through its design and configuration, the cockpit emphasizes the sporting and driver-oriented character of BMW's new Coupe. Taking a seat behind the wheel, the driver will immediately focus on a newly designed instrument cluster which includes an oil temperature gauge positioned below the tachometer.

Buckling up in the new BMW 3 Series Coupe, both the driver and front passenger benefit from the newly developed belt feeder arm: The seat belt integrated in the B-pillar, moved back in typical coupe fashion, is automatically 'delivered' to the driver and front passenger once they close the door and once the key has been inserted into the ignition slot. Connected to the seat occupancy detector, the passenger-side belt feeder arm is only activated when the front passenger has actually taken a seat. With the belt delivery unit housed conveniently within the side panels, this new system does not impair the elegant look of the interior.

Access to the two seats at the rear has been made even easier. The lever for releasing the seat position is fitted in perfect ergonomic arrangement at the top on the outside of the backrest.

The new BMW 3 Series Coupe was conceived from the start as a four-seater. Comfort for rear seat passengers is further enhanced by the center console which includes individual storage boxes with a cover on top, additional air outlet vents and footwell lights.

The world of the BMW Coupes: combining traditional and new values

The mission to develop a coupe has always been a particularly demanding but interesting challenge for the automotive engineer. After all, the driver opting for a coupe is a truly discerning driver looking for the ultimate driving experience. With this in mind, BMW has succeeded time and again over the years in meeting the great demands made of the coupe buyer while, at the same time, consistently resetting the benchmark in this segment.

The coupe has a long tradition at BMW. Even back in the 1930s, the BMW 327 was lauded as a truly outstanding two-seater and remains a legend to this day. Even back then, the coupe was widely appreciated as a particularly sporting grand tourer with two doors and a fixed roof.

These fundamental features remain virtually unchanged to this day. The lines typical of a coupe combine a long and sleek front section with a dynamic roof line tapering out gently to the rear. Únlike a thoroughbred sports car, the typical coupe offers ample space for more than just two occupants as well as a separate luggage compartment providing room for ample luggage.

The new BMW 3 Series Coupe takes up proven traditions in terms of drive technology as well. Developing a coupe, BMW always seeks to enter new dimensions in driving dynamics. This is why particularly powerful engines and new chassis control systems regularly make their debut in a coupe. Now the new BMW 3 Series Coupe is continuing this tradition with BMW's new twin-turbo inline six featuring high-precision fuel injection.

As a modern interpretation of a traditional car concept, the new BMW 3 Series Coupe is unquestionably a very special car. Even more than its predecessor, the new 3 Series Coupe stands out from its Sedan counterpart through its distinctive design. In the process the new BMW 3 Series Coupe ensures a particularly refined combination of active driving pleasure and visual appeal.

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

The BMW 3 Series established the compact sports sedan segment 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 segment. 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 with any typical customer segment. 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 segment. 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 with a two-door version.

1975: The first generation.

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 with compact dimensions and a sporty character has its very own distinctiveness. The kidney grille dominates the front end and with 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 with a powerful look. This is complemented by state-of-the-art, sporty suspension technology with 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 with 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 with 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 segment's first six-cylinder engine, the models 320 and 323i being fitted with disc brakes all round especially for this purpose.

The BMW 323i in particular soon gains a reputation as a supreme, athletic model, which – with 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.

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 with 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 with a catalytic converter. Those responsible demonstrate courage with 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 with permanent four-wheel drive. The transfer gearbox with 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.

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 with 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.

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 with two balance shafts. The technically most prominent measure implemented on the six-cylinder petrol engines is the introduction of double VANOS. Along with the intake and exhaust camshaft, this fully automatic and infinitely variable adjustment technology provides the engine with 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 with 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 with 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 with 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 with 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 with 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 segment. 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 with 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.

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: with 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 segment. 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 segment sedans.

In addition to excellent handling and thanks to coherent rear-wheel drive technology and steering 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 with 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 with six cylinders: BMW 320/6 and BMW 323i.

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 with 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 with sports oriented drivers. Tuners, fitters and conversion specialists alike were in great demand and virtually all suppliers were involved with this BMW 3 Series top model. Along with the revised four-cylinder engines, a new entry-level model, the BMW 315 with 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 with 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 with 102 kW/139 hp offered superior performance and, thanks to a five-speed transmission with 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 with a modest 8.4 litres of regular petrol per 100 km. Furthermore, it was the first BMW 3 Series model to be supplied exclusively with 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 with 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.

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 with 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 with 142 kW/193 hp assumed the role as the top-of-the-range model – with 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.


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 with 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 with 135 kW/184 hp and 4-valve technology, direct fuel injection, turbocharger with 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.

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 with new Common Rail Injection of the second generation and a turbocharger with 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 with 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 with 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 with 85 kW/115 hp and the BMW 318i with 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 with an average fuel consumption of just 4.1 l/100 km.
