2008 BMW 3 SERIES SEDANS AND SPORTS WAGONSThe Best Is Now Even Better
When the editors of Car and Driver magazine selected the BMW 3 Series as one of their 2007 '10Best' Cars' for an unprecedented 16 years in a row, they wrote, '... the 3 Series is the definitive sports sedan, delivering the driving satisfaction of a sports car in the body of a practical machine. For a car enthusiast, everyday drivers don't come any better.' #
For 2008, the best sports sedans and sports wagons in the compact luxury §egmènt receive new equipment including optional transmission paddle shifters mounted behind the §teering wheel available when the vehicle is equipped wîth a 6-speed STEPTRONIC automatic transmission and the Sport Package. New 16-in light alloy wheels are standard on wîth the 328i and 328xi Sedans. Those models now feature standard chrome tailpipe tips. In addition, HD Radio is now available for less at $350.
EfficientDynamics: Efficient power
The 328i Sedan and Sports Wagon and the all-wheel drive 328xi Sedan and Sports Wagon, are powered by BMW's 3.0-liter inline 6-cylinder wîth aluminum/magnesium engine block, producing 230 horsepower and 200 lb-ft of torque; a 15 hp and 15 lb-ft of torque improvement over the previous models.
The 335i and 335xi Sedans obtain their motivation from the 3.0-liter twin-turbocharged inline 6-cylinder engine wîth a cast aluminum engine block producing 300 horsepower and 300lb-ft of torque. This is a 45 hp and 80 lb-ft of torque improvement over the 2006 330i models.

The BMW twin-turbo 6-cylinder engine
It is the most powerful engine within BMW's wide range of inline 6-cylinder engines that does not wear an 'M' badge. The twin-turbo engine, designated N54, develops a maximum output of 300 horsepower in ÚS specification from 3.0 liters displacement and generates peak torque of 300 lb-ft for powerful acceleration in any situation. And it achieves these results using technology that might surprise students of BMW history: turbocharging.
Although it is standard equipment on its highly acclaimed diesel engines, BMW has not used turbocharging wîth a road-going gasoline powerplant since the 1980's. Úntil now, the BMW 745i Sedan, which debuted in 1981, and the iconic BMW 2002 Turbo, introduced at the 1973 Frankfurt auto show, were the only two standard production, gasoline-powered BMWs to employ the technology.
While the technology works as advertised, BMW engineers were not satisfied wîth the most often-cited downside to turbocharging; the frustrating 'turbo lag' that occurs when the driver presses the accelerator pedal and when the turbocharger develops sufficient rotation to increase power. Turbo lag is at its worst at low engine speeds. Other drawbacks included relatively high fuel consumption and poor emissions output. At the time, turbocharger technology was not a reliable, practical or efficient was to make power. For these and other reasons, BMW put turbocharged gasoline engines on the shelf for more than 20 years.
Two recent developments caused BMW to reconsider turbocharging. While many luxury-performance carmakers began to achieve power gains by building engines of ever-increasing displacement, BMW looked for a more efficient way wîth smaller engines and turbocharging made sense. Also, the technology transfer from BMW's turbocharged diesel engines could easily be transferred to their gasoline-fired counterparts. Accordingly, BMW articulated its new approach to developing high-performance engines as part of its EfficientDynamics initiative.
The N54 features twin, relatively small turbochargers to boost performance significantly, but, at the same time, minimize turbo lag. Thanks to their lower inertia, two small turbochargers build up pressure much faster than a single, large turbocharger, thus eliminating even the slightest lag.
A further in advantage of turbocharging is that this is the most weight-efficient to boost engine power and performance. The N54 turbocharged inline engine weighs approximately 150 lbs. less than an equally powerful eight-cylinder engine displacing 4.0 liters. This lower weight means a significant advantage not only in fuel economy, but also in balancing the car's weight distribution.
To enhance efficiency, 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/xi Sedans 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 easy to feel on the road.
This high-performance engine develops its power and performance much more spontaneously than a turbocharged engine of conventional design. At the same time, the N54 engine offers all the smoothness and refinement which made BMW's award-winning inline sixes so admired well. Last, but certainly not least, the impressive increase in power on the twin-turbo engine versus a normally aspirated six-cylinder engine comes without any significant increase in fuel consumption.
Turbocharging typically includes intercooling of the engine's induction air, in other words, cooling the compressed air heated by the combustion process, from the turbocharger(s). Sometimes that's accomplished wîth coolant; in the case of the N54 engine, it's accomplished wîth outside air. Intercooling is desirable, often necessary to reduce the temperature of the incoming air to preclude detonation or 'knocking' that can reduce power or, in the extreme, damage the engine. Of course, the N54, like the normally aspirated N52 and other current BMW engines, is equipped wîth knock control.
As effective as the magnesium/aluminum engine construction is for saving weight, the significantly increased loads and cylinder pressures of the N54 300-horsepower engine required the use of an aluminum engine structure wîth cast-iron cylinder sleeves. Some, but not all, of the N52's magnesium/aluminum weight saving was lost in this process. All together, the N54 weighs 419 lb; the N52 357.
A high-pressure direct fuel injection system utilizing so-called piezo injectors also enhances performance and fuel efficiency. A 2nd-generation evolution of the system found on the BMW 760's V12 engine is a key factor in achieving BMW's goals for the N54. The system's in advance over its predecessor is that it provides the engineers a greater degree of freedom in the calibration of fuel quantity and timing and the distribution of the fuel-air mixture in the combustion chambers.
A piezo injector, a recent advancement in fuel injector technology, uses an actuator that takes the place of the solenoid valve in a conventional injector. The actuator, which works significantly faster than the solenoid, reduces the injector's response time. That results in, according to researchers who led the piezo injector's development, a 2 - 3% fuel savings and 20% less emissions.
For the first time in a 3 Series Sedan, the exhaust pipes run under both sides of the vehicle from the engine compartment to under the rear bumper, creating a true dual exhaust system. At low loads, a flap channels most exhaust gases through one side to reduce low-frequency exhaust 'rumble.'
The engines deliver impressive 0-60 mph acceleration performance improvements versus their predecessors, specifically:
• 328i Sedan - 6.3 sec. (manual) 6.9 sec. (automatic)
0.4 sec./0.3 sec. improvement
• 328xi Sedan - 6.9 sec. (manual) 7.1 sec. (automatic)
0.2 sec./0.6 sec. improvement
• 335i Sedan - 5.4 sec. (manual) 5.6 sec. (automatic)
0.7 sec./0.7 sec. improvement
• 328i Sports Wagon - 6.5 sec. (manual) 7.1 sec. (automatic)
New 2007 model
• 328xi Sports Wagon - 7.1 sec. (manual) 7.3 Sec. (automatic)
0.2 sec./0.6 sec. improvement
Galvanic silver trim matching the trim around the start/stop button has been applied to the climate control knobs adding a premium touch to the console. The sport §teering wheel, available wîth the optional Sport Package, is now the same as that of the 3 Series Coupes' wîth galvanic accents. Satellite radio preparation is standard.
The fifth generation of the 3 Series
From their low, wind-slicing front end through an upswept silhouette to a high trunk lid or large-area tailgate that enhances aerodynamics and cargo space, the '07 3 Series Sedans and Sports Wagons are a logical progression from their predecessors. Not only does the first glance tell you that these are BMWs; it also tells you clearly that they are 3 Series.
Compared to their predecessors, these models are larger in every dimension. Their wheelbase it is up by 1.4 in., length is 2.2 in. greater for the Sedans, 1.9 in. for the Sports Wagons. Width has increased a full 3.0 in. and the current models are 0.8 in. (Sedans) or 1.0 in. taller. These increases in exterior dimensions translate into greater safety capabilities, enhanced luxury and comfort equipment and greater passenger and cargo space: shoulder room, front head room, rear knee room and EPA-rated passenger and cargo volumes have all increased.
Technology and features:
Compared to its predecessor, the current 3 Series offers abundant new technology and features in these two categories:
• Engines wîth Valvetronic variable valve lift

• Power rear-window sunshade and manual rear side-window sunshades
Chassis engineering: improving on tradition
In concert wîth the more powerful engines, the chassis now has the benefits of BMW's double-pivot front suspension to the 3 Series. The 5-link rear suspension further perfects the 3 Series' unique blend of agility and stability. Chassis/body rigidity has been further improved and run-flat tires are standard equipment. Four-wheel ventilated disc brakes have been refined extensively and the Dynamic Stability Control system adds an array of functions.
Double-pivot front suspension. Though familiar from BMW's larger models (5, 6 and 7 Series as well as the X3 and X5 Sports Activity Vehicles) the double-pivot front suspension concept is a recent feature of the 3 Series. It is a more elaborate system than that of the previous 3 Series models, featuring two lower arms (hence the name 'double-pivot') that work in concert wîth the spring/shock absorber strut. The system provides:
• Small positive §teering offset, for best §teering feel and control under all road conditions. The two arms don't actually intersect; if you visually extend their axes to a point where they do intersect, you find a 'virtual pivot point' that is ideal for achieving this result. (Steering offset is the 'lever arm when' through which road forces act on the suspension system.)
• Large §teering caster, for outstanding stability in straight-line driving and excellent §teering return action coming out of curves.
• Space for large brakes, by virtue of the two lower arms' arrangement.
Further advantages are found in the details:
• The trailing (forward) lower arm has a rubber/hydraulic cushion, which provides highly effective 'compliance' for enhancing ride comfort.
• The transverse (rearward) lower arm is cushioned by a finely tuned rubber element that promotes direct and precise §teering response in corners and curves.
• Extensive aluminum componentry in RWD models for low unsprung weight. This improves the suspension's response to bumps and other road irregularities; it can markedly improve riding comfort and, on any irregular road surface, handling as well. In these models, aluminum components include: both lower arms, §teering knuckle, brake calipers and the brake shields.
In addition, the subframe that carries the front suspension of RWD models is made of aluminum, as is the §teering rack. These components are not unsprung but do contribute to overall weight reduction and, being up front, also to the typical BMW near 50/50 weight distribution. The subframe adds rigidity, in enhanced §teering precision and is also an integral element in the vehicle's management of energy in a frontal crash.
Because their front suspension handles drive forces as well as those of §teering, cornering and braking, the AWD 'xi' models have mostly steel components in this area.
5-link rear suspension
In its concept, the 3 Series' 5-link rear suspension can be described as a double-A-arm wîth an additional lateral track rod; the upper and lower A-arms are actually two links each, their vertical positions differing. This is analogous to the front suspension's dual lower arms.
The advantages of this rear suspension system are numerous:
• As at the front, there is a virtual pivot point for each pair of links, giving the engineers similar freedom in optimizing the system's geometry for best handling. Also as at the front, the axis connecting these virtual points is configured to ensure that driving, braking and road forces all act effectively on short leverage. The result is very precise handling, especially insensitive to road disturbances.
• Únder cornering forces the system controls geometry in such a way as to achieve contradictory qualities; the degree to which they are mutually achieved is a measure of a suspension's excellence.
• Contributing to the outstanding geometry is the wide and rigid basis on which the rear tires are 'planted' on the road. The lateral links are extremely rigid also, as is the subframe.
• All suspension links connect to the subframe; no longer does any link pivot directly from the body structure. This further reduces the effects of road irregularities on riding comfort, and improves handling precision as well.
• The large and elaborate subframe enhances energy management in a crash, including the more severe rear-end impact that the current models are designed to withstand.
As always wîth BMWs, the final drive (differential) it is also mounted to the sub frame through rubber, creating acoustic decoupling that minimizes the transmission of driveline noises into the body. Widely spread mounts to the body, in an area where the body structure is particularly rigid, further help optimize the combination of precision and ride comfort. The rear suspension system, sub frame and brake calipers are all of steel.
Steering: evolution standard; revolution optional
The 3 Series' engine-speed-sensitive variable-assist power rack-and-pinion §teering system has generated universal praise. An auto magazine once described it as 'nearly telepathic.' This standard §teering system continues essentially unchanged, although wîth a somewhat less direct overall ratio of 16.0:1. Yet numbers don't always tell the entire story, for the suspension and sub frame have already sharpened the 3 Series models' reaction to §teering inputs.
The 'revolution' here is the optional Active Steering for RWD 3 Series models, previously available on the 5 and 6 Series.
xDrive: BMW's 'intelligent' all-wheel drive system
The 328xi Sedan, 328xi Sports Wagon, and 335xi Sedan incorporate BMW's advanced xDrive AWD and traction. xDrive operates as follows:
• Driving torque is always transmitted to the rear wheels, and most of the time, to all 4 wheels.
• The portion of the torque transmitted to the front wheels is controlled by a multi-disc clutch that can be fully open, fully engaged or at any degree of partial engagement in between. The torque split between rear and front wheels is steplessly variable.
• Engagement pressure on the multi-disc clutch is directed by an electronic control system in response to actual road and driving conditions.
xDrive doesn't just optimize traction; it can also enhance both agility and stability on grippy as well as slippery road surfaces. Via the same type of logic that Dynamic Stability Control employs to recognize and correct for excessive over-and understeer, xDrive adjust the front/rear torque split to avoid these tendencies. If undesirable oversteer is sensed, the multi-disc clutch is completely closed, sending the maximum possible torque to the front wheels. If excess understeer is detected, xDrive opens the clutch lines completely, sending no driving torque to the front wheels. In the BMW tradition, the driver enjoys optimum vehicle dynamics under a wide range of driving and road conditions.
The exterior design:
3 Series tradition, freshly expressed
The current 3 Series consistently reflects the direction set by BMW design wîth the 7 Series in 2002 and evolved wîth the 5 Series in '04. At the same time, it is true to its heritage, radiating the dynamic presence that has increasingly characterized this Series wîth each new generation.
At the front. In this face of strong character, distinctively formed four-beam headlight units wrap around and taper to a precise point, emphasizing in the front view the vehicle's width and in profile its short front overhang. With the Xenon Adaptive lights (optional 328i/xi models, standard 335i/xi models), BMW's distinctive and popular luminous rings function as additional parking lights and also illuminate when the headlights are on.
In profile: Sedans. There is much 'swing' in the side view: the hood cut line, sloping upward and then continuing to become the beltline and on past the C-pillar; a strong character line corresponds to that of the previous 3 Series, but sets up a stronger convex/concave intersection. Taillights that wrap well around into the body sides form an esthetic 'punctuation' while enhancing visibility of the vehicle from the side – an active-safety factor. 328i/xi Sedans have all-black side-window framing; 335i/xi Sedans have chrome and black.
Sports Wagons. Identical from the A-pillars forward and using the same front doors, the Sports Wagons take on their own (but consistent) character from the B-pillar rearward. The roofline and the side windows' upper line taper downward while the beltline continues upward, creating an expressly sporty wagon profile. Standard roof rails add swing and function to the profile as well.
At the rear: Sedans. A graceful arc connecting the taillight edges through the integral spoiler's lower edge is at the top; the top of the spoiler is the continuation of a line that begins in the C-pillar. Below the spoiler, the surface goes concave toward the license-plate recess. The trunk's outer edges sweep down into the bumper, making a conveniently low loading height also a visual treat. Functional/esthetic shapes are sculpted into the lower bumper area to help organize airflow at the back of the vehicle.
Sports Wagons. The side beltline wraps around to become an across-the-tailgate character line just under the separately opening rear windows. At the top, an integrated roof spoiler forms a graceful conclusion to the roofline, helping smooth airflow and incorporating the 3rd brake light. Like the Sedan‘s trunklid, the tailgate reaches down into the bumper for a low loading height.
Aerodynamically, this is the smoothest 3 Series yet. At 0.30, the rear-wheel-drive Sedans are a 'point' better than the previous models' 0.31; at 0.31, the Sports Wagons are also a point better than their predecessor. The overall shape of either body style is calibrated to maintain low aerodynamic lift at higher speeds; a visually interesting and also functional sharp edge at the taillights' corners helps ensure efficient airflow at the rear.
Improved corrosion-proofing and paint processes
In preparing to produce the 3 Series, BMW has further developed its rustproofing and paint processes. The refinements include:
• Body shell now virtually fully galvanized, for further enhanced corrosion resistance. Standing behind this claim is BMW's 12-year/unlimited-mileage Rust-Perforation Warranty.
• Pre-paint preparation further improved. Bodies for the 3 are cleaned and prepared for priming in a 12-zone process.
• Rotation dipping for pre-paint preparation and primer application. This improves the cleaning process, and means that primers and corrosion-proofing coats reach even more fully into the body's nooks and crannies.
Ergonomics and luxury: more space, enhanced functionality, and elegance
In addition to greater space, the 3 Series interior offers reduced noise levels, improved climate control and a host of features – standard and optional – that enhance luxury and convenience. And the design of the interior is just as fresh as the exterior.
As always in BMWs, the driver enjoys his or her experience at the wheel partly because BMW has designed the interior to optimize that experience. All operational and informational elements essential to driving are grouped on and around the §teering wheel; although many aspects of the control layout are updated, the most central informational element remains the traditional pair of round analog instruments directly in front of the driver.
A sharp eye will note that the two front door panels differ: on the passenger side there's a sloped vertical door pull; on the driver's side, where the power-window controls are neatly grouped on the armrest, the door pull is integrated into that armrest. Both front doors include large storage bins.
In a choice exclusive to the 3 Series, the instrument panel is offered in two forms: standard, wîth a single hood above the instrument cluster; and optional, wîth a double-wave theme creating a second hood over the optional Navigation/iDrive control display. With the latter configuration, there is also the iDrive controller between the front seats.
Automatic climate control
Though the previous 3 Series has excellent automatic climate control, the current models' system offers an even higher level of performance, sophistication and features. Features include –
• Separate left and right temperature controls vs. the predecessors' single temperature control.
• Temperature- and volume-controlled rear air outlets that give rear passengers greater control over their environment.
• Climate-controlled center console compartment.
• Mist sensor. Via the windshield wipers' rain sensor, misting of the windshield is sensed visually and system operation adjusted to clear it up.
• Heat at Rest. Allows heating the interior for a limited time wîth the engine off. Familiar from larger BMW models but a recent enhancement to the 3 Series; facilitated by the engine's electric coolant pump.
• Maximum a/c setting for rapid cool-down at a single touch of a button.
• Increased blower power means not only increased maximum cooling or heating power, but also quieter operation at the normal blower speeds that are now a smaller proportion of maximum.
• Further optimized design of ducts and outlets, also cutting airflow noise.
• Automatic reduction of blower speed when the vehicle comes to a stop, for yet another reduction in noise.
• Indirect airflow via outlets atop the dash, for pleasant, draft-free climatization (not for defrosting or demisting).
• Recall of individual users' settings via Key Memory:
- Manually selected air distribution (windshield, body-level, footwells)
Other thoughtful features continue from the previous system:
• Active-charcoal microfilter ventilation
• Bi-directional solar sensor for front compartment (takes into account the intensity and direction of solar heat in determining cooling of interior)
• Automatic recirculation control, wîth specific sensing capability for diesel exhaust.
Two audio systems, two subwoofers
As before, two audio systems are offered. One is the 10-speaker system that's standard in 328i/xi models; the other is the acclaimed 13-speaker Logic7 system – optional in 328i/xi, standard in the 335i/xi models and making its 3 Series debut. Both systems include two subwoofers in BMW's patented positions, in cavities at the bases of the B-pillars ('under the front seats').
To the 10 speakers of the 328i/xi standard system, Logic7 adds a center-fill speaker to the instrument panel and two midrange speakers in the rear doors; all speakers are upgraded. Logic7's digital Surround Sound process provides uniquely realistic reproduction, generating a 360° sound field and accurately re-creating the acoustic intent of the original studio master.
Úpholstery and trim: standard wood, optional leather
Leatherette upholstery is standard in all models; leather is available in four colors. Dark Burl Walnut trim is standard; lighter-tone Poplar Natural and aluminum trim are available at no extra cost. Following a lead set by the 5, 6 and 7 Series,'galvanic' trim appears on the instruments‘ and Start/Stop button‘s outer rings and several other interior detail elements; this elegant material has a plastic core, wîth a true metallic surface applied galvanically in several layers and a clear top coat to protect against corrosion.
Seating choices, including sport seats wîth adjustable backrest width
Height-adjustable, 6-way manual front seats are standard in 328i/xi models; 8-way power seats are optional in 328i/xi and standard in the 335i/xi models. Sport seats wîth adjustable backrest width are available, a feature first seen in the M3 Coupe. Available in both Sedan models are split folding rear seats and an interior-to-trunk pass-through wîth ski bag.
Seating choices are only one amenity among the many enjoyed by drivers and passengers in the 3 Series. Others include –
• Auto-dimming interior and exterior mirrors, the latter offered on this Series for the first time.
• A digital compass, set into the interior mirror.
• A standard 2-way power moonroof wîth more opening area than before on the Sedans; on the Sports Wagon, an even larger dual-panel moonroof.
• Voice Command, included in the Navigation/iDrive option.
• Available Bluetooth interface for cellphones.
• Front and rear overhead consoles, each wîth separate left/right reading lights, Ambiance Lighting and other features. Predecessor models had an overhead console and Ambiance Lighting only at the front.
• Footwell lighting
• A fold-up rear center armrest.
Increased cargo space, handy trunk features in Sedans
Elimination of the spare tire and jack, possible because run-flat tires are standard across the board, has helped create approximately 12% more cargo space than before. Moreover, the official EPA measurement on which this claim is based does not include a deep well under the trunk floor that encloses about 1.75 cubic feet and offers a place to store smaller objects without worry of their moving around when the vehicle is in motion.
Sports Wagons interior and cargo area
Úp front, the Sports Wagons offer the same accommodations as the Sedans, except as affected by the Wagons' Panorama moonroof. Front and rear leg room are identical for the two body styles; front and rear head room are almost identical. The Wagons' standard split folding rear seats offer essentially the same functions and benefits as those that are optional in the Sedan.
The big difference, of course, is aft of the rear seats, where in terms of load-carrying ability and versatility the Sports Wagons offer advantages not only over the Sedans, but also over its predecessor. As always wîth a BMW – the 328i/xi abound wîth rational design and thoughtful details:
• High-lift tailgate, electrically released from remote or interior switch.
• Separately opening rear window, for convenient loading without opening the tailgate.
• Fully lined cargo area – floor, sides, back sides of rear seats – wîth luxurious, yet long-wearing carpet.
• Wider than that in the previous Wagon, and wîth straight, essentially vertical sides, the cargo area presents various cargo possibilities:
- 16.2 cubic feet of volume wîth the seats upright and cargo loaded to the top of the seats
- 24.8 cubic feet wîth the seats upright and cargo loaded to the ceiling
- 60.9 cubic feet wîth the seats folded and cargo loaded to the ceiling
- Luggage straps on the right side
- Bag holder at either side
- 12-volt accessory power outlet on the left-hand wall.
- Cargo cover, concealing cargo when the seats are upright; user has option of -having cover rise when rear window or tailgate is opened (by tapping the release twice) or remaining in place (by tapping once).
- If, once raised, a rear-seat backrest is not fully locked into place, a red tab appears to help call users' attention to it.
- A cargo net, carried in a roller assembly wîth the cargo cover, that can be mounted wîth the rear seats either upright or folded
- Red light at left bottom of tailgate, for safety; visible when tailgate is open.
A Cargo Compartment package, which offers additional storage configurations, is available as a BMW center-installed accessory.
Dual-panel Panoramic Moonroof
With its large roof opening, this feature gives occupants almost the feeling of being in a convertible. The power glass roof consists of two panels, both of which can be tilted up at the rear. The forward, larger panel can also be slid open; together, their glass area is almost 6.5 square feet. Although the glass is effectively tinted, there is also a power-operated interior shade; 1-touch operation is provided for all motions, including that of the interior shade.
Safety engineering and features: improving on a star performer
The previous 3 Series' safety performance has long been recognized by authoritative, independent observers:
• After conducting its own offset crash test of a 3 Series Sedan for the March 11, '99 issue, Germany's auto motor und sport magazine concluded, 'Occupant protection by the new 3 Series is already at such a high level that only marginal improvements can be imagined.'
• And in the Ú.S., the Insurance Institute for Highway Safety, after conducting its own crash test of the 3 Series Sedan, concluded simply, 'A Best Pick.'
In developing the vehicle structure, BMW's safety engineers set out not just to match, but to improve on, the predecessors‘ excellent safety performance. Integrated into this overall goal were specific targets, including –
• Achieving 5 stars in the Euro-NCAP (New Car Assessment Program) offset frontal crash test
• Meeting the new Ú.S. FMVSS (Federal Motor Vehicle Safety Standard) 301, which specifies a brutal 50-mph rear-end offset crash. The impact is taken by 70% of the test vehicle's width; not only must stringent injury criteria be met, but the fuel system must remain free of leaks.
• Meeting the new IIHS (Insurance Institute for Highway Safety) 'SÚV side-impact' test, in which an impact from a tall vehicle at 50 km/h (31.1 mph) is simulated.
Various engineering approaches toward the 3's even higher-performing structure included:
• Úse of high-strength steels in the large-section structural elements.
• Targeted application of further types of steel, including multi-phase types, at various points to promote effective energy management.
• Developing and improving energy paths by which the immense forces of frontal crash impacts are led through the structure and dissipated. Here, the engineers concentrated on optimizing the interaction between front-end deformation and the ability of the passenger space to remain intact. For severe frontal collisions – especially offset, when one side of the vehicle takes the brunt – they found ways to transfer the forces into the other side, so that the more heavily impacted side doesn't have to absorb all the forces. The resulting extremely high energy-absorption capability is the basis for keeping the passenger space intact – and for optimum calibration of passive-safety systems such as safety belts and airbags.
In side impacts as well, the structure is similarly designed to transfer impact energy to the side away from the impact. Here the IIHS's 'SÚV test' raised the bar for occupant safety in severe side collisions. Elements that manage this massive impact energy include the –
- floor structure
- doors, which retain BMW's effective interlocking door anchoring system
- reinforced B-pillars
- dash structure, which functions as much more than just a carrier for • instruments, climate control, etc.
- roof framing.
• In rear-end impacts, the deformable area consists of –
- two longitudinal structural members
- the trunk floor and lid (Sedans) or tailgate (Sports Wagons)
- trunk or cargo-area side walls, as integral elements of the overall body-side structures
- various additional reinforcements.
Here, the engineers worked to ensure that even in the radically severe offset rear-end crash specified by FMVSS 301, the passenger space would remain intact, the doors could be opened and the fuel system would still be sealed.
The structure is virtually fully galvanized, enhancing corrosion resistance and thus helping preserve its strength and energy management over the years.
Front-to-rear Head Protection System. Now all BMW Sedans and Sports Wagons have this feature. Compared to the 5 and 7 Series' inflatable-tubular/sail system, the
3 Series‘ curtain-type system takes up less space in the headliner – an advantage for the compact 3 Series. Like the tubular system, BMW's curtain-type HPS can remain inflated for several seconds after initial deployment, an important function in case of rollover.
Automatic safety-belt tensioners and force limiters front and rear. Long standard on BMW front safety belts, these features now enhance the outboard rear belts' effectiveness as well.
Occupant-detection sensor. BMW has long employed a sophisticated electronic control strategy for managing the deployment of airbags and safety-belt tensioners. This approach now becomes even more precise, thanks to a sensing mat in the front passenger seat. Called OC3, the mat is more highly sophisticated than its predecessor; it measures the weight and analyzes the pressure distribution of the occupant in order to distinguish between an adult and an infant in a child safety seat.
Features for protecting the driver's feet and knees. Two measures reduce the likelihood of injuries to the driver's feet and legs:
• The footrest is designed to crush under the force of the driver's left foot, so that the full impact force is not transmitted to his or her foot and leg.
• Brake and clutch pedals move forward under impact force, also reducing force transfer to the driver's feet and legs if they are on the pedals.
Options: an expanded range offers appealing choices
The program of factory options is notable not only for its extent and variety, but also because many features formerly available only on or in the 'higher' 5, 6 and 7 Series now become available in this more accessible Series. Among these are a 6-speed automatic transmission, Active Steering, Active Cruise Control, Comfort Access, window sunshades for the rear and rear-door windows, Xenon Adaptive headlights, iDrive, Voice Command, Navigation wîth real Time Traffic Information, the Logic7 audio system and factory-installed Sirius Satellite Radio.

The benchmark sports sedans set a new benchmark
'Few cars have inspired as much competition as this family of perennial pacesetters,' raved Car and Driver in its January '05 10Best awards, 'and fewer still resisted so successfully. What's the 3 Series' secret? Smooth, 6-cylinder power, exemplary ergonomics, silky-smooth shifting supple ride quality, eager responses, superb seats and proportions that never look out of date.'
While all these attributes play an important part of defining the success of the BMW 3 Series its iconic status over the years is mostly derived from how it drives. Though many of BMW's competitors have tried, and are still trying to, no one else quite knows how to match this winning combination which is the quintessential driver's car.
Performance wîth a conscience
BMW strives to produce its motor vehicles and other products wîth the utmost attention to environmental compatibility and protection. Integrated into the design and development of BMW automobiles are such criteria as resource efficiency and emission control in production; environmentally responsible selection of materials; recyclability during production and within the vehicle; elimination of CFCs and hazardous materials in production; and continuing research into environmentally friendly automotive power sources. Tangible results of these efforts include the recycling of bumper cladding into other vehicle components; water-based paint color coats and powder clear coats; near-future availability of hydrogen-powered models; and various design and engineering elements that help make BMWs easier to dismantle at the end of their service life.

The success story of a global trendsetter: Five generations of the 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.
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.
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.
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.
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.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. 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.
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.
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.
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.Source - BMW
