Front section with bold shapes and an emphasis of width

The front view of the Saloon and Touring models of the new BMW 3 Series is characterised by a clear emphasis of vehicle width. The characteristic brand look of the double circular headlights is underscored by means of chrome tubes, and their corona rings can now also be used in the BMW 3 Series Saloon and the Touring model with optional bi-xenon headlamps as daytime running lights. The light sources of the direction indicators have a ribbed structure and LED direction indicator lights are installed in conjunction with the optional bi-xenon headlamps.

Side view with elegantly elongated lines

Powerfully taut surfaces and striking character lines dominate the side view of the new BMW 3 Series. The contour edges of the side skirts have been set higher and modelled in a more distinctive fashion. Another new feature is the exterior mirrors with two distinctive character lines, echoing the interplay between the convex and concave shaping of the surfaces. The mirrors also offer an enlarged field of vision.

The rear: sporty and tight with a new lighting design

As a dynamic concept, BMW ConnectedDrive offers the products BMW Assist, BMW Online, BMW TeleServices and BMW Tracking, depending on the country in question. At the same time BMW ConnectedDrive is designed for the ongoing further development of services to increase mobility and information convenience. The Enhanced Emergency Call with automatic positioning
and remote control functions are examples of safety-related options which are already available, extending the lead of BMW ConnectedDrive over the competition.

The new BMW 3 Series: the engine of success for BMW EfficientDynamics

With its further optimised engine range, the new BMW 3 Series further extends its leading position in the segment in terms of driving dynamics and economy. With all engine types, both the Saloon and the Touring model boast superior fuel consumption and exhaust emission levels than those of their competitors of comparable output.

Depending on the model-specific constellation, the new BMW 3 Series features the latest measures for increased efficiency. All petrol and diesel engines available for the new BMW 3 Series represent the state of the art in engine development. What is more, an extremely wide spectrum of efficiency-promoting measures has been applied within the engine environ-ment so as to further reduce fuel consumption and exhaust emissions.

2009 BMW 3-Series
- image 256046

This includes Brake Energy Regeneration, Auto Start/Stop Function, Shift Point Display, the needs-oriented control of auxiliary units, electro-mechanical power steering, tyres with reduced rolling resistance and Automatic Air Intake Flaps. With the comprehensive application of these technologies in what is the most successful BMW model series in terms of sales figures, the development strategy BMW EfficientDynamics achieves an especially broad impact.

New 6-cylinder diesel engine in the BMW 330d

In accordance with BMW EfficientDynamics, every new BMW offers increased driving dynamics in combination with reduced fuel consumption and exhaust emission levels as compared to its respective predecessor model.

An especially striking example of this is the BMW 330d. Its 3.0 litre all-aluminium engine has common rail injection of the third generation, whose piezo injectors operate at a pressure or up to 1,800 bar, and a turbocharger with variable turbine geometry. The new diesel engine achieves its maximum output of 180 kW/245 bhp at an engine speed of 4,000 rpm, while its maximum torque of 520 Nm is available from 1,750 to 3,000 rpm. The new BMW 330d accelerates in 6.1 seconds from zero to 100 km/h, its maxi-mum speed is electronically cut off at 250 km/h. The average fuel consumption of the new BMW 330d according to the EU test cycle is 5.7 litres per 100 kilometres, its CO2 level is 152 grams per kilometre.

BMW BluePerformance technology: prepared for the exhaust gas norm EU 6.

- image 256045

The new BMW 330d is fitted as standard with a diesel particulate filter and an oxidation catalytic converter. Thanks to the innovations applied to the new 6-cylinder engine, it significantly undercuts the thresholds set for the exhaust gas norm EU 5. In the oxidation catalytic converter, hydrocarbons and carbon monoxide are converted to water and carbon dioxide. For further reduction of nitrogen oxides in exhaust emissions, a NOX-storage catalytic converter can be integrated in the exhaust gas treatment system of the new 6-cylinder diesel engine, in addition to the oxidation catalytic converter. In the optional configuration with BMW BluePerformance technology, the new BMW 330d even meets the requirements for classification according to the future exhaust gas norm EU 6.

Like the new BMW 6-cylinder diesel engines, the engines of the models BMW 320d and BMW 318d also meet the requirements of the exhaust gas norm EU 5 as standard. Their 4-cylinder diesel engines have been modified in a number of details, and the further reduction of exhaust emission levels has been implemented so as to have no impact on fuel consumption and the acoustic properties of the engines.

Engine selection: the greatest variety and highest level of efficiency in the segment.

The ideal combination of driving fun and efficiency also characterises the other engines available for the new BMW 3 Series. Spontaneously responding, high-torque 6-cylinder and 4-cylinder diesel engines, powerful and high-revving 4-cylinder petrol engines and the 6-cylinder in-line petrol engine well-known for its unique refinement and dynamic power delivery form a portfolio which is unequalled in the segment of the BMW 3 Series.

2009 BMW 3-Series
- image 256066

With five petrol engines and five diesel engines, the new BMW 3 Series offers the most extensive range in its segment. When it comes to both petrol and diesel power units, customers have the choice of four 4-cylinder and three 6-cylinder engines. The output range extends from 105 kW/143 bhp in the 4-cylinder models BMW 318i and BMW 318d to a 225 kW/306 bhp in-line 6-cylinder engine in the BMW 335i. All engines are available for both the BMW 3 Series Saloon and the Touring model, and all are combined with the latest BMW EfficientDynamics measures in the environment of the engine, as suits the specific model configuration. Each of the ten engine types thus has a more favourable relationship between driving dynamics and economy
as compared to competitor vehicles of similar output.

As one of a number of features which are unique within the competitive field, all petrol engines are fitted with High Precision Injection and all diesel engines combine an all-aluminium crankcase, turbo charging and common rail direct injection of the third generation. The BMW 335i is especially dynamic, accelerating in just 5.6 seconds from zero to 100 km/h. The outright leader in terms of efficiency in the entire vehicle segment is the BMW 318d with an average fuel consumption in the EU test cycle of 4.7 litres per 100 kilometres and a CO2 emission level of 123 grams per kilometre.

Optimised all-wheel drive system BMW xDrive – now for the BMW 320d xDrive too.

The new BMW 3 Series also presents a further expanded selection of engine types for combination with the intelligent all-wheel drive system BMW xDrive. For the first time it is possible to fit 4-cylinder models of this series with xDrive. The new BMW 320d xDrive combines outstanding efficiency with superior properties in terms of driving dynamics and traction. Both for the Saloon and the Touring of the new BMW 3 Series it is now possible to combine three petrol engines and two diesel engines with the intelligent all-wheel drive system BMW xDrive. The models in question now bear the designations BMW 335i xDrive, BMW 330i xDrive, BMW 325i xDrive, BMW 330d xDrive and BMW 320d xDrive.

2009 BMW 3-Series
- image 256081

The electronically controlled permanent all-wheel drive system BMW xDrive offers an incomparable level of comfort, traction and agility over all surfaces due to its flexible distribution of drive torque between the front and rear axles. In order to ensure especially precise control, the computer unit of the drive stability regulation system Dynamic Stability Control (DSC) and that of xDrive are networked with each other in the Integrated Chassis Management (ICM). With these capabilities, xDrive supports driving dynamics because it identifies any tendency to oversteer or understeer early on and counteracts effectively.

Superior chassis technology, Active Steering as an option

The new BMW 3 Series has the most sophisticated chassis technology in its segment. At the rear axle there is a five-link construction which is adapted to the needs of the especially high-power and high-torque engines. The front axle of the BMW 3 Series also reflects a unique standard of engineering. The dual-arm tension strut axle with stabiliser is largely made of aluminium.

The standard equipment also includes an electro-mechanical steering system with integrated Servotronic function for speed-related steering support. Active Steering is also optionally available: here, steering transmission is adapted to road speed.

Optimised occupant protection with crash-active headrests

2009 BMW 3-Series
- image 256089

The safety concept of the new BMW 3 Series is based on a solid body structure, the selective application of high-strength steel types and special deformation elements which divert and absorb impact energy. In addition there are six airbags, 3-point automatic belts and headrests on all seats to offer occupants optimum protection. What is more, ISOFIX children’s seat mounts on the rear seats are a standard feature. The front seats of the new BMW 3 Series are fitted as standard with crash-active headrests which significantly reduce the risk of injury to the cervical spine in the event of an impact. Controlled by the vehicle’s safety electronics system, this feature ensures that in the event of a rear-on collision the front section of the headrest is moved forward by up to 60 millimetres and upwards by as much as 40 millimetres. This reduces the distance between headrest and head, thus increasing the stabilising and securing function of the headrest.

A contribution to active safety is made by the new generation of adaptive headlight, optionally available in conjunction with bi-xenon headlamps. It guarantees illumination of the road surface when taking a corner. Here the swivel direction of the headlamps is derived from the steering angle, the yaw rate and the road speed of the vehicle. At low speeds the turning light is activated. This function is performed by one of the two inside headlamps, depending on the direction. Before each turning manoeuvre, the light cone is turned specifically in the appropriate direction to illuminate the road ahead.

Best heating and climate comfort in the segment

In the area of comfort fittings, too, the new BMW 3 Series has a range of optimised features to offer. The further developed heating and air conditioning technology ensures that the interior maintains the desired temperature throughout the year. The new BMW 3 Series has the most high-performance heating and cooling system in its category. Within one minute the entire interior air volume can be completely exchanged three times. In spite of the outstandingly high air through-flow rate, excellent acoustics are ensured by means of a flow optimisation function in the unit and its feed lines and by means of an air outlet positioned at the centre of the instrument panel.

2009 BMW 3-Series

A 2-zone air conditioning system is optionally available with individual temperature controls for the driver and front passenger.

The design

The current 3 Series, already strong on BMW dynamism and identity, now gains an additional measure of both by virtue of discreet updates and refinements. At the rear, a widened track enhances these vehicles’ planted-on-the-road stance; careful and subtle modifications to the front, sides and aft end make the total design even more harmonious.

2009 BMW 3-Series
- image 256073

At the front. A new, bolder front spoiler/bumper ensemble imparts sportier, stronger character. Its center air intake is larger than before, enhancing the air supply for mechanical components; upswept lines in the lower air intakes, the bumper itself and the newly shaped headlight clusters emphasize the wide stance. Double longitudinal hood lines, more 3-dimensional than ever, rise toward the A-pillars and frame the hood’s power dome. New lighting features include the layered turn-signal lenses, and on models with Xenon Adaptive headlights, BMW’s distinctive luminous rings now serve as Daytime Running Lamps (on all models, they also function as parking lights). The optional Park Distance Control now includes front and rear monitoring.; formerly PDC was offered on the 3 Series in a rear-only version.

In profile. The lower character line that runs from just behind the front wheel well to just ahead of the rear wheel well, is more prominently contoured and strongly expresses the low stance. On Sport Package-equipped models, new high-gloss Shadowline (black) trim more elegantly frames the side windows. And new wheel designs freshen the 328i models’ 16-in. and the 335i/335d models’ 17-in. standard equipment.

2009 BMW 3-Series
- image 256076

At the rear. Restating BMW’s traditional L-form are the taillight clusters of both Sedan and Sports Wagon models. Their two main segments, for the taillights and turn signals, are composed of LED rows for an even higher-tech look than before. On Sedans, the trunklid is newly shaped to go with the new taillight design. And the 0.6-in.-wider rear track does its part to strengthen an already road-gripping stance.

New colors. BMW paint colors are notable for their richness and eye-catching appeal. A total of 12 colors are offered with three new metallics for ’09: Space Gray, Tasman Green and Blue Water.

Interior: high-quality materials, enhanced ergonomics and a new-generation iDrive system

Subtle updates to materials and surface textures make the 3 Series interior even more attractive; refinement of interior design and amenities include enhanced placement of power-window controls for driver and new, expanded storage possibilities.

2009 BMW 3-Series
- image 256091

In the 3 Series, BMW’s iDrive control and display system is included in the Navigation option. As in the new 7 Series (where iDrive and Navigation are standard), a 4th generation of iDrive sets new standards for ergonomics, efficiency and logical functionality with its new, higher-definition, 8.8-in. Control Display. More uniformly structured menus and an optimized control strategy for the display and console-mounted controller are also signature new features.

Other new details include keys for direct selection of the Radio, CD, Navigation and Telecommunications menus, grouped conveniently next to the controller. Visual assists and consistent hierarchies in the display simplify choices within the individual menus. In the Navigation section, users will experience a new and superior level of brilliance, detail and variability of map displays. A “map preview” function facilitates selection of the navigation destination from a list; in a new operational logic, letters of the alphabet and numerals are arranged in circular form for more intuitive input of addresses and phone numbers.

Hard drive for audio and Navigation data storage

2009 BMW 3-Series
- image 256070

Newly included in the Navigation option is a hard drive for storage of Navigation data (such as destinations) and audio material (such as music). The large capacity hard drive means quick access, and allows transfer of material from a CD, MP3 player or a USB stick to the hard drive, which can hold up to 8-GB of music.

The doorsill trims with their distinctive BMW script are new. The somewhat smaller iDrive controller has a fine galvanic surface, and is newly surrounded by the direct-select keys that enhance iDrive’s user-friendliness. There’s a larger storage tray in the center console including the auxiliary audio input and providing an appropriate place to lay an audio source. Door-panel design has been refined too; on the driver’s door the power-window and –mirror controls have been moved 2 cm rearward for an easier, more natural reach.

Colors and color contrasts have been improved, as well. Three new colors for the optional Dakota leather upholstery are offered: Oyster, Saddle Brown and Chestnut Brown. Interior trim choices are updated, too, with a new Fine Line aluminum trim replacing the former brushed aluminum and Light Burl Walnut replacing Light Poplar among the available wood trims.

2009 BMW 3-Series
- image 256092

Lastly, a heated steering wheel – much appreciated by drivers of other BMW Series in winter weather – has been added to the optional Cold Weather Package for all models.

In general, the interior space – with its attractive interplay of convex and concave surfaces, its sporty elegance and technology-oriented esthetics is more appealing than ever.

BMW Efficient Dynamics in the new 3 Series

In its competitive field, BMW is known for powertrains that achieve an outstanding combination of performance and fuel efficiency. In addition to the commendable mileage ratings of the 3 Series’ gasoline engines, the newest evidence of BMW’s EfficientDynamics approach is the new twin-turbo diesel engine of the likewise new 335d Sedan model, which combines the new-age diesel performance that has swept European motoring in recent years with truly remarkable Miles per Gallon.

The new 335d Sedan: power, torque and remarkable fuel efficiency. All with refinement and sound worthy of a BMW

In Europe, where fuel prices have historically been – and remain – much higher than in the U.S., vehicle manufacturers have achieved dramatic gains in the performance, smoothness, quietness and emission control of diesel engines…while maintaining the diesel’s historic superiority in fuel efficiency. Now, with the new 335d Sedan, BMW brings this progress to the U.S., with brand-new technology that meets the U.S.’ strictest emission standards.

Like all ’09 BMW gasoline engines, the 335d’s new diesel is constructed with a weight-saving aluminum cylinder block – something that’s not taken for granted given the diesel’s much higher compression pressures. (All BMW engines have aluminum cylinder heads.) It is an inline 6-cylinder engine maintaining a defining BMW tradition that means exceptional smoothness and unique sound.

In addition, several diesel-specific technologies of this new engine contribute to its achievement of true high performance, diesel fuel economy and clean exhaust:

2009 BMW 3-Series
- image 256043

Common-rail direct fuel injection. One of the most important innovations of recent diesel development, this has replaced the individual-cylinder or distributor-type injection systems of earlier diesel engines.

Common Rail (CR) means that a single, very high-pressure fuel-delivery pump supplies all cylinders, the fuel traveling along a common “rail” or distributor line. From there, fuel is injected at extremely high pressure (1800 bar/2645 lb./sq in.) directly into the cylinder.

The basic novelty of common-rail injection was to divorce the production of fuel pressure from the actual injection process; this was necessary to give the diesel engine what gasoline engines have long had, namely completely electronically controlled fuel injection. CR also facilitates multiple injections per combustion cycle. In all, this was a breakthrough that made possible dramatic strides in diesel power, efficiency and emission control.

Piezo injectors. A further breakthrough, already applied by BMW in the 335i (and other BMWs) models’ twin-turbo gasoline engines. With direct injection, the injectors – that critical component injecting fuel into each cylinder’s combustion chamber – are subject to especially high temperatures and pressures. Instead of most injectors’ conventional electrical valves, a “stack” of piezo crystals reacts lighting-fast to impulses from the engine electronics governing the injector needle’s opening stroke and duration for ultra-precise control. This, too, facilitates major advances in fuel economy and emission control, in gasoline, as well as diesel engines.

2009 BMW 3-Series
- image 256063

Variable Twin Turbo technology. In contrast to the two small, equal-size turbochargers of BMW’s twin-turbo 6-cylinder and V-8 engines, the diesel employs two turbos of different sizes.

At low engine speeds, intake air does pass through the large turbo, but it’s the smaller, lower-inertia one that does the air compressing (turbocharging). Thanks to its optimum efficiency within this rpm range, it provides effective boost for driving from a standstill up to modest acceleration rates and driving speeds. So it is that this engine develops a good 390 lb-ft. of torque at as low as 1500 rpm – a remarkable achievement that will amaze first-time 335d drivers and continue to thrill those who drive this BMW regularly.

With increasing engine speed, the larger turbocharger begins to take over: first as a pre-compressor for the smaller one, then progressively until it becomes the primary turbo. The engine reaches its maximum of 425 lb-ft. by 1750 rpm, and then maintains this immense torque level until 2250 rpm going on to reach its peak power of 265 hp at 4200 rpm.

Diesel combustion, power and torque characteristics. In its most basic distinction from gasoline engines, a diesel engine achieves its combustion not with a sparkplug, but by much “harder” compression of the fuel-air mixture; the 335d engine, for example, has a compression ratio of 16:5:1, vs. 12.0:1 in today’s ultra-high-performance BMW M gasoline engines and the 10.2:1 of the 335i twin-turbo gasoline unit. For one thing, this requires a significantly stronger engine structure; indeed, the 335d engine weighs more than its 335i counterpart.

2009 BMW 3-Series
- image 256047

The diesel combustion process also produces very different torque and power characteristics. Whereas the 335i engine reaches a maximum torque of 300 lb-ft. @ 1400-5000 rpm and a maximum power of 300 hp @ 5800 rpm, the 335d attains its maximum torque of 425 lb-ft. @ 1750-2250 rpm and its maximum power of 265 hp @ just 4200 rpm. In general, diesels have this low-speed-torque, lower-rpm character and in their vehicular application, they are geared differently. The 335d, for example, comes only with automatic transmission – an automatic is the ideal partner for a diesel engine – and its final drive ratio is 2.81:1, vs. 3.46:1 for the 335i with automatic transmission.

Diesel engines also employ a different fuel, the product of a different refining process from that of gasoline. The two fuels are not interchangeable; gasoline cannot be used in a diesel engine, and vice versa. Their prices typically diverge; at any time or in any location, demand may be different for the two, and government taxation policies for gasoline and diesel fuel also diverge.

Stellar pulling moxie, full-bore acceleration – and fuel efficiency. The huge torque output of 425 lb-ft. at relatively low engine speeds speaks for itself; 335d drivers will marvel at this engine’s robust response at low to medium speeds. The peak power output of 265 hp also speaks for itself, as does the resulting 0-60-mph time of 6.0 sec. While official EPA mileage estimates are not yet available, preliminary tests indicate 23 mpg city and 33 highway.

Most advanced exhaust gas management: SCR catalyst with AdBlue injection

2009 BMW 3-Series
- image 256041

BMW Advanced Diesel with BluePerformance optimizes emission management by incorporating an oxidation catalyst placed close to the engine, a diesel particulate filter housed in the same unit, and an SCR catalyst with urea injection. Apart from filtering out even the smallest particles from the flow of exhaust gases, this combination ensures effective reduction of nitric oxides (NOX) by way of a chemical reaction within the exhaust system initiated by the injection of a small dose of urea referred to as AdBlue. The ammonia (NH3) generated in this process within the SCR catalyst subsequently converts the nitric oxides (NO and, respectively, NO2) in the exhaust gas into environ¬mentally compatible nitrogen (N2) and vapor (H2O).

BMW has developed a two-tank system for AdBlue ensuring convenient use of this new technology with all the benefits and ease required by the customer: The amount of AdBlue required in each case is drawn from the active tank comprising approximately 1.6 gallons by means of a dosage pump. And since the urea solution would freeze at a temperature of −11oC, this active tank, as well as the dosage pipes are heated.

AdBlue technology by BMW: reduced emissions without additional service appointments

2009 BMW 3-Series
- image 256066

The active tank is connected to a second reservoir, the so-called passive tank. With its additional capacity of approximately 4.5 gallons, this passive tank offers a plentiful supply of the urea solution required within the car. The average range provided on this supply capacity is indeed sufficient to have the tank system replenished as part of normal scheduled maintenance.

From the active tank AdBlue is delivered to the dosing valve and atomized into the exhaust emissions. Consistent distribution of AdBlue within the flow of exhaust emissions is ensured by the SCR mixer. The ammonia generated in this way in the hot emission gas subsequently acts in the SCR catalyst as a reduction agent and converts environmentally harmful nitric oxides into nitrogen and water vapor in a process referred to as selective catalytic reduction.

This process gives the special SCR catalyst its name with the SCR system as such being masterminded by highly efficient engine management. A nitric oxide sensor, finally, provides information on the concentration of NOX in the exhaust emissions.

The large amount of AdBlue provided in the reservoir enables the customer to go on driving as before without having to change service intervals or observe any particular requirements, thus benefiting from the advantages of this environmentally friendly emission technology throughout the entire running life of the car without any additional service or visits to the workshop. During the first four years or 50,000 miles, the replenishment of AdBlue will be covered as part of the BMW Scheduled Maintenance program: not only will there be no additional inconvenience, but no addition cost during that period.

328i and 335i models

Two quite distinct inline 6-cylinder gasoline engines power all other 3 Series models; these remain unchanged in the new ’09 models.

In the 328i models – Sedan and Sports Wagon, rear-wheel- and all-wheel-drive models – a 3.0-liter unit with advanced, weight-saving magnesium/aluminum composite construction and Valvetronic variable valve lift provides smooth, sonorous and fuel-efficient power.

Valvetronic, a patented BMW innovation, varies valve lift to regulate engine power; when the driver steps down on the accelerator pedal, instead of a throttle opening wider, intake-valve lift increases. A throttle imposes a restriction to incoming air; Valvetronic eliminates this restriction, significantly enhancing efficiency particularly at low to medium speeds. This is reflected in excellent fuel economy, plus very spontaneous response to that accelerator pedal. Valvetronic also enhances engine smoothness in idling and gentle driving, and makes for excellent cold starting.

This engine delivers 230 hp @ 6500 rpm and has a 7000-rpm redline, so it is in the great tradition of smooth, powerful and high-revving BMW gasoline engines. Yet its torque peak of 200 lb-ft. occurs at relatively low engine speed for a gasoline engine – 2750 rpm – so it’s also a responsive partner in everyday driving, not requiring frequent shifting to maintain a brisk pace with the standard 6-speed manual transmission. 0-60-mph times for the 328i Sedan are 6.3 sec. for the manual, 6.9 sec. for the automatic; 2008 EPA city/highway mileage ratings are 18/28 mpg with manual, 19/28 with automatic. Acceleration times and EPA ratings vary for the Sports Wagon, and for the Sedan and Sports Wagon in their xDrive (all-wheel-drive) versions.

335i models: also 3.0-liter inline 6, twin-turbo, even more brilliant performance

The 335i Sedan and its AWD stablemate 335i xDrive are powered by a totally distinct 3.0-liter inline 6, with an aluminum block, different bore and stroke dimensions, and most importantly twin turbochargers. High-pressure direct fuel injection with piezo injectors, a concept shared with the 335d diesel engine, and special turbo-related cooling features complete the description of an engine that has garnered almost delirious praise in the enthusiast media and beyond. It develops a full 300 hp @ 5800 rpm, has the same 7000-rpm redline as the 328i engine, and generates a fulsome 300 lb-ft. of torque all the way from 1400 to 5000 rpm – a somewhat diesel-like characteristic.

Here the twin turbochargers are both small, each of them serving 3 of the 6 cylinders. Their small size enables them to respond quickly to the driver’s demands reducing turbo engines’ historical “turbo lag” to a minimum. This engine does not have Valvetronic, as turbocharging works best on a gasoline engine with a conventional throttle. On-the-road performance is stunning: 0-60 mph in just 5.4 sec. with manual transmission, 5.6 with automatic; and that broad, generous torque band produces abundant acceleration even at lower speeds in the upper gears. EPA mileage ratings are equally impressive: 17/26 mpg with either transmission for the 335i, slightly less for the xDrive version.

Transmission choices: 6-speed manual or automatic, shift paddles optional

All 3 Series transmission choices are 6-speeds. The manual gearbox, standard on all models, is engineered to provide what buyers want when they choose it: precise control and a high level of driving pleasure.

BMW also places a high priority on active driving pleasure with its automatic transmissions. Recent refinements to the 3 Series’ automatics have improved their sportiness, precision and efficiency: a torque converter that slips less, quicker shifting, finer adaptation to driving style and conditions. All BMW automatics include a Sport mode that quickens shifting and holds the lower gears longer; and a Manual mode that allows the driver to take charge of virtually all shifting.

Steering-wheel-mounted shift paddles are added on all automatic 3 Series models with the Sport Package, and include a Direct Selection feature: When the driver is motoring along in Drive and makes a shift via paddle, the transmission goes into the Manual mode.

BMW iDrive, 4th generation

In the 3 Series, BMW’s iDrive system of controls and displays is offered in combination with the optional Navigation system. In the new 3 Series Sedans and Sports Wagons, iDrive enters its 4th generation building upon this pioneering development, while making it more natural, more intuitive, simpler and more elegant in its functionality – and more esthetically pleasing and enjoyable. In offering this new generation of iDrive, the
3 Series joins the new 7 Series that is also being introduced this autumn.

More intuitive operation, expanded functions

With the 2002 7 Series, BMW initiated a new direction in the control of vehicle features and functions; via a multi-menu color display and a mouse-like controller usable by driver and passenger alike, a potentially crowded landscape of buttons and knobs was supplanted by a computer-logic control path.

An overarching attribute of iDrive was the separation of control (via the console controller) and display (the centrally placed iDrive monitor). This basic arrangement remains; the controller has been further developed and the display has evolved markedly.

Positioned centrally in the instrument panel, the new control display sets higher standards for logical, readily understood menus and attractive graphics. The controller has been refined for comfortable, intuitive selection and activation of functions via standardized turn, push and tilt motions, while being augmented with new direct-selection keys for specific menus, plus more of the Programmable Memory Keys that were added to the system in the 3 Series in 2007-08.

Greater functionality, satisfying to use: controller with direct-selection keys.

Benefiting from the newest biomechanics R&D, the state-of-the-art controller operates with tactile precision and clearly structured motions. New control elements, menu schemes and graphic representations in the control display become evident upon first use, yet user appreciation grows over the longer term. A graphic depiction of the controller in the display itself helps orient the user to the next control step; the rotation, pressing and tipping motions generally correspond to those of a computer mouse.

Thus interpreted, rotation of the controller takes the user through menu selections; pressing it makes the choice. Tilting the controller to the left or right effects navigation through various menu levels. Via clear graphic organization in the form of stacked layers and onscreen depiction of controller movements, the user enjoys highly intuitive navigation. All menus are structured according to a consistent scheme, so that one is almost immediately at ease; menus are broad so that the user can view relatively numerous options without switching to another level. Also, functions are arranged so that in longer-term use the most important options are reached more rapidly.

An additional new refinement is four direct-selection keys, placed adjacent to the controller, for the most frequently used menus. These allow quick selection of CD, radio, phone and navigation menus, and are augmented by three further keys of general utility: one takes the user directly to the start menu (MENU), one to the most recently active menu (BACK), and the third (OPTION) presents various options within the current area. Thus searches are likely to be shorter, or unnecessary.

Familiar and proven, yet now more useful: Programmable Memory Keys.

An iDrive enhancement recently introduced in various BMW models represents a further user convenience: Programmable Memory Keys. When first introduced, there were six of them; now there are eight. Lined up above the audio controls, these allow the user to capture and store favorite or frequently used functions (radio stations, phone numbers, navigation destinations for example) on various keys and recall them instantly. The stored functions can be as specific and detailed as a navigation map in the preferred scale or an audio balance setting. And because the keys are sensitive not just to being pressed but also to being merely touched, one can see the stored function on the control display by lightly touching the key. If it’s the right one, the user need only press the key and it’s there, ready to use.

High-resolution display, preview maps and full-screen images.

With its 8.8-in., high-resolution monitor, the new iDrive displays remarkably attractive images. It’s a system appropriate to the vehicle it’s in, achieved via up-to-date hard- and software. White-on-black menu lists; effective symbols and icons; contemporary graphics; and clear, consistent color-coding are among the elements that enhance not only function but also esthetics.

Menu structures, too, make finding desired functions easier. In the Start Menu, all functional areas served by iDrive are listed. Selecting a given item leads to its menu layer, where the options of that level are also listed. This consistency in navigation assists in orienting the user, as does the “stacking” of menu layers in the display. Visual assists further contribute to clarity. And if the user gets to a place where he or she didn’t mean to be, the Back key usually reverses the error.

User-friendlier Navigation

This overall refinement of functionality means simpler and more enjoyable use of the optional Navigation. Full-screen map displays offer outstandingly detailed views of the geography; maps as well as specific symbols can be shown in 3-dimensional form. Selected points of interest along the travel route appear with near-photographic realism.

Mere input of destinations reveals the new system’s impressive capabilities. If the destination appears on a list in the system, a preview map appears as the user scrolls the list; this can help distinguish between places with similar or identical names. If a destination (or a phone number) needs to be entered manually, this is done with a new, circular “speller” that makes the entry go more quickly.

Convenient combination of voice entry and controller operation.

Yet, another iDrive innovation is its ability to combine voice and controller entry called Multi-mode Input. The user can go back and forth between the two methods, while actually inputting; indeed, voice recognition can remain active during input via controller and the user can modify an input via voice. Voice recognition – BMW calls it Voice Command – is activated by its function key on the steering wheel, and de-activated either upon completion of the action or by pressing the key again. Voice Command is simplified by visual display of the available commands, yet its capabilities go further in that numerous synonyms of these commands are also recognized.

This newly enhanced iDrive introduces a very significant step forward in the operation of automotive features and functions. Greater efficiency, improved logic and clear, attractive displays help define and advance the 3 Series’ unique product character. The new iDrive helps the freshened 3 Series Sedan and Sports Wagon create a user experience that is truly unique.

BMW xDrive

Increasingly, customers – particularly those who drive in snowy winter conditions – want all-wheel drive. In the 3 Series, five models – with new “xDrive” model designations – incorporate BMW’s unique and advanced AWD system of the same name.

2009 BMW 3-Series
- image 256084

This permanent, electronically controlled system varies the split between front- and rear-wheel driving torque according to driving conditions to produce an incomparable degree of comfort, traction and agility. Via a smooth, precisely controlled central multi-disc clutch, it directs torque to the wheels where the traction is best, reacting amazingly quickly to each change in driving conditions.

In most normal driving situations, xDrive apportions 40% of the driving torque to the front wheels, 60% to the rear to provide a typical BMW rear-wheel-drive handling feel. Sensors continuously and sensitively monitor the four wheels, detecting even the tiniest amount of slip; torque distribution adjusts in fractions of a second to match changing conditions. It all occurs so quickly, in fact, that the system almost seems to be anticipating slip; the driver is unlikely to perceive the need to adjust the torque split before xDrive accomplishes it.

2009 BMW 3-Series
- image 256092

Enhancing xDrive’s quick and precise action is the networking of xDrive and Dynamic Stability Control, the traction and stability system that’s standard on all BMW models. As part of BMW’s overall Integrated Chassis Management (ICM), this powerful and capable networking helps calibrate xDrive torque distribution and other chassis functions to instantaneous conditions. Thus xDrive and DSC react to varying road traction or abrupt steering, braking or acceleration by the driver, always endowing the vehicle with optimum stability and agility.

Via ICM, xDrive and DSC detect any incipient excessive over- or understeer, adjusting 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 excessive understeer is detected, xDrive opens the clutch completely, sending all the torque to the rear wheels. In true BMW tradition, the driver enjoys optimum vehicle dynamics under a wide range of driving and road conditions. Finely dosed application of individual wheel brakes compensates for side-to-side traction variations, as well: this aspect of DSC was improved upon the current 3 Series’ introduction, via new analog brake actuation in this situation, as well as other stability-related or anti-lock brake interventions.
