New design accentuations for a sporty, elegant appearance. With striking design accentuations to the front section, the side perspective and the rear, the dynamic character of the new BMW 3 Series Saloon has been given additional emphasis, while the new BMW 3 Series Touring enhances its sporty, elegant profile with new visual features which are recognisable from all perspectives. 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. Greater emphasis of the vehicles power and sporty character likewise characterises the rear view of the new BMW 3 Series. To achieve this effect, the rear bumpers, rear lights and luggage compartment handle have been completely redesigned. The dual section rear lights are now structured according to the characteristic BMW L shape. The two LED rear light clusters and the direction indicators in LED technology are designed to create a striking, high-quality appearance. The widened track of the new BMW 3 Series especially contributes to its powerful appearance. Depending on the model, the track of the rear axle has been widened by up to 24 millimetres by means of a new wheel carrier and other modified details.

High-quality materials and optimised ergonomics in the interior. The modern, high-quality interior of the BMW 3 Series has been further enhanced by means of specific modifications in the selection of materials and surface design. Here the modern design concept is also applied, with its convex-concave surfaces, sporty elegance and technology-oriented aesthetic style. Premiere for the new generation of the operating concept BMW iDrive. The operating system BMW iDrive is optionally available in the new BMW 3 Series for the activation and control of entertainment, information, navigation and telecommunications functions, whether standard or optional. The new generation of iDrive is available in conjunction with the optional navigation system Professional. What is more, the new iDrive supports multi-mode operation by voice entry. With the new iDrive generation, BMW extends its lead over comparable systems made by other manufacturers in terms of display quality and intuitive operation. Using the four direct selection buttons grouped around the Controller, it is especially easy to switch spontaneously between CD, radio, telephone and navigation functions. The functional bookmarks are supplemented with three control buttons. Control Display with high-resolution graphics and variable layout. The new iDrive in the BMW 3 Series is presented with a 8.8 inch Control Display whose dimensions surpass all graphic displays available to date in the automobile field. With its high image resolution it offers significant improvement in the display of detailed graphics. The structure of the user menu also makes it easier to locate desired functions. All functions controllable by iDrive are listed in the starter menu. Hard drive for audio files and navigation system. The features of the navigation system Professional include a hard drive integrated in the vehicle. The storage medium with a capacity of 80 GB provides outstandingly fast access to digital maps for navigation purposes and can also be used for an extensive collection of music files. The system enables music files to be transferred to the hard drive from a CD, MP3 player or USB stick. World premiere for unlimited internet use inside the vehicle. BMW ConnectedDrive makes BMW the first automobile manufacturer in the world to enable unlimited use of the internet inside the vehicle when stationary. Internet access is available for the new BMW 3 Series as a special equipment option at attractive flat-rate conditions. The transfer of data is based on EDGE technology (Enhanced Data Rates for GSM Evolution), which unlike UMTS offers full geographical coverage and is three to four times faster than

was introduced in the BMW 3 Series for the first time worldwide in 2005, provides a weight reduction of around 24 per cent as compared to conventional aluminium crankcases. In the BMW 330i, the 2,996 cubic centimetre 6-cylinder petrol engine delivers a sporty 200 kW/272 bhp at 6,700 rpm, in the BMW 325i the figures are 160 kW/218 bhp at 6,100 rpm. The maximum torque is 320 Nm between 2,750 and 3,000 rpm in the BMW 330i and 270 Nm between 2,400 and 4,200 rpm in the BMW 325i. For the sprint from zero to 100 km/h, the BMW 330i Saloon requires no more than 6.1 seconds (Touring: 6.2 seconds). The electronically limited maximum speed is 250 km/h for both body types. In the EU test cycle the average fuel consumption is 7.2 litres per 100 kilometres for the Saloon and 7.3 litres for the Touring model. The BMW 325i accelerates from zero to 100 km/h in 6.7 seconds (Touring: 6.9 seconds), the maximum speed is 250 and 248 km/h respectively. The average fuel consumption according to the EU norm is 7.1 litres (BMW 325i Saloon) and 7.2 litres (BMW 325i Touring) per 100 kilometres. Light, powerful, efficient: 4-cylinder engines with High Precision Injection. In the 4-cylinder petrol engines for the new BMW 3 Series, too, the engine developers have opted for High Precision Injection. The light alloy engine with a capacity of 1,995 cubic centimetres lines up for the start with two levels of output. Both engines have the second generation of petrol direct injection in so-called lean operation mode. In this way, both the BMW 320i and the BMW 318i benefit from this innovative technology consisting of piezo injectors centrally placed in the cylinder head which precisely dose the fuel and feed it into the combustion chambers in layers of differing concentration. The crankcase of these two engine types is made of aluminium. The main difference in design is the use of a controlled intake tube in the more powerful version. In the BMW 320i there is a 4-cylinder engine with an output of 125 kW/170 bhp at an engine speed of 6,700 rpm, with maximum torque available at 4,250 rpm. This enables an acceleration rate from zero to 100 km/h in 8.2 seconds (BMW 320i Saloon) and 8.4 seconds (BMW 320i Touring). The maximum speed is 228 km/h (Touring: 226 km/h). In the EU test cycle the BMW 320i has an average fuel consumption of 6.1 litres per 100 kilometres (Touring: 6.2 litres).
BMW Media Information 7/2008 Page 29
With an output of 105 kW/143 bhp at 6,000 rpm and a maximum torque of 190 Nm at 4,250 rpm, the second 4-cylinder engine also offers an excellent basis for sporty driving performance. The BMW 318i Saloon and BMW 318i Touring both achieve 210 km/h as their maximum speed, for the acceleration from zero to 100 km/h they require just 9.1 seconds (Saloon) and 9.5 seconds (Touring). In the EU test cycle the average fuel consumption figures are 5.9 litres per 100 kilometres for the Saloon and 6.0 litres for the Touring model. State-of-the-art diesel technology for the BMW 3 Series. The three 6-cylinder and the two 4-cylinder engines share an all-aluminium crankcase, turbocharging and common rail direct injection of the third generation. All diesel engines of the new BMW 3 Series are fitted as standard with a particulate filter of the latest generation and an oxidation catalytic converter which are integrated in a joint casing. The exhaust gas purification unit is located directly at the engine. It reaches its operating temperature immediately after the engine starts, thus taking full effect very early on. The particulate filter is maintenance-free and regenerates automatically by means of diesel particle combustion. The filter function operates across the entire engine speed and load range without influencing engine output or fuel consumption. The models BMW 330d, BMW 330xd, BMW 320d and BMW 318d already meet the requirements for the exhaust gas norm EU 5, which does not come into force until 2009. Already fit for the exhaust gas norm EU 6: the new in-line 6-cylinder-diesel in the BMW 330d. BMW takes a step towards an even further reduction in exhaust gas emissions with the latest version of the 6-cylinder diesel engine. The completely newly developed power unit can be additionally fitted with BMW BluePerformance technology. What is more, the engines exhaust system which is fitted as standard with a diesel particulate filter and an oxidation catalytic converter can be optionally supplemented with an NOX storage catalytic converter to reduce nitrogen oxide emissions. This makes it the first BMW engine to fulfil the exhaust emission regulations of the planned exhaust gas norm EU 6, which does not come into force until 2014. Due to the NOX storage catalytic converter, the emission of nitrogen oxides is effectively reduced without any impact on the output and fuel consumption level of the engine. In its construction, in a large number of its components and in the arrangement of the auxiliary units, the engine in the new BMW 330d is significantly different from the predecessor engine, with 10 kW increase in output and a fuel consumption level reduced by about 7 per cent. The common rail direct injection of the third generation now operates at a maximum pressure of

The new generation of the operating concept BMW iDrive: Simply fascinating.
Newly designed Controller, 8.8 inch Control Display. Optimised menu structure, high-resolution graphic display, extended range of functions. Additional comfort with direct selection buttons at the Controller and freely programmable functional bookmarks.
The pioneering operating system BMW iDrive is optionally available in the new BMW 3 Series for the activation and control of all standard and optional entertainment, information, navigation and telecommunications functions. The new generation of iDrive featured in conjunction with the optional navigation system Professional. In addition to a newly designed Controller in the central console there is an 8.8 inch Control Display with optimised high-resolution graphic display and freely programmable functional bookmarks below the DVD insert as well as additional direct selection buttons grouped around the Controller. In the new BMW iDrive, the operating element, i.e. the Controller in the central console, and the display element the central Control Display remain consistently separated. This ensures optimum ergonomic positioning of the controls and presentation of information with limited distraction of view from the road. The extremely large 8.8 inch display integrated in the instrument panel sets the benchmark in the competitive field with its clearly structured display and easily comprehensible, visually attractive graphics. It is at the same height as the instrument panel and is at optimum viewing distance for both the driver and the front passenger. Inviting functionality and excellent long-term benefits: Controller with direct selection buttons. The new iDrive Controller is now more effective to operate. The benefits of the controls, the menu structure and the graphics of the Control Display are revealed both on first contact and in the course of long-term use of the system. An image of the Controller shown in the Control Display facilitates orientation in selecting the next operating step. The operating steps activated by turning or pressing the Controller are very similar to mouse-clicks or wheel movements performed at a computer: turning the knob takes the user through a list of selectable menu items, while pressing it confirms the desired selection.
BMW Media Information 7/2008 Page 34
Simple navigation through the menu levels. By pushing the Controller to the left and right it is simple to navigate through the various menu levels. The customer is provided with maximum orientation due to the clear graphic arrangement in the form of stacked panels and the display of Controller movements currently permitted. In this way the operating options provided by the Controller and the graphic display supplement each other perfectly. All menus are structured according to a uniform scheme which significantly shortens the familiarisation period. At the same time, the functions are arranged in such a way that in the course of long-term use the most important functions are reached most quickly. Another new feature of the Controller is the four direct selection buttons for the most frequently used menu items. These buttons can be used for to switch spontaneously between CD, radio, telephone and navigation functions. The direct selection buttons are supplemented by three control buttons which serve to initiate start menus, return to the last active menu and show additional options in the current context. Well-established but now with an even higher degree of individualisation: the functional bookmarks. With its versatility, BMW iDrive supports the personal operating preferences of the driver, thereby offering yet another bonus in terms of comfort and individuality. The functional bookmarks located in the area of the audio system in the central console also serve this function. In addition to radio stations, telephone numbers and navigation destinations, these eight buttons can now also be used for speed selection of other iDrive menu items, too. This means that with a simple press of a button, the driver is able not just to select his favourite radio station or home address but also have the navigation map displayed to his favourite scale, obtain an overview of traffic bulletins or regulate the loudspeaker balance of the audio system. Large-format display with variable layout, preview maps and full-screen display. The new iDrive in the BMW 3 Series offers an 8.8 inch Control Display. With this high resolution it provides significantly enhanced display of graphic details. The structure of the operating menu also makes it easier to find the desired function. The flat menu trees and the user system derived from computer technology simplify rapid access to the desired functions.

BMW Media Information 7/2008 Page 35
Maps and symbols can also be display three-dimensionally. The use of the navigation system Professional is also simpler and more attractive now thanks to the optimised technical functions of BMW iDrive. The full-screen map display function offers an incomparably detailed overview of the region currently being visited. As an addition to the perspective display already provided, it is now also possible to have an altitude map displayed. Selected places of interest along the route are highlighted in the form of photographically realistic graphics. The special map view under the menu item Highlight traffic situation provides an up-to-date convenience not just in urban traffic. In this view, current tailback information is marked in red on the display. On the motorway, this system ensures the driver always has a helpful overview when it comes to route changes due to traffic jams. Operation by voice and Controller can be conveniently combined. Another innovation of the iDrive system is that of multi-mode operation by voice and Controller. The customer can switch easily between each mode while performing a single task, and if necessary the voice control function can remain active during Controller entry, to be used at the same time. It is activated by pressing the relevant button on the multifunction steering wheel. Hard drive for audio files and navigation system. The features of the navigation system Professional also includes a hard drive integrated in the vehicle. This data medium has a capacity of 80 GB and enables exceptionally rapid access to digital navigation maps thereby setting a new benchmark. The hard drive can also be used for an extensive collection of music files. The system enables music files to be transferred to the hard drive from a CD, MP3 player or USB stick. The iDrive system can be used to access a personal music collection, a CD, another external player or the radio. The memory capacity available for music files is equivalent to about 100 audio CDs. In the vehicle database the individual music files are stored along with title and details of the artist.

BMW ConnectedDrive: A network for increased safety and comfort.
Intelligent networking of driver, vehicle and environment. Extended range of practical services in the new BMW 3 Series Saloon and in the new BMW 3 Series Touring. World premiere: use BMW ConnectedDrive to surf freely on the internet.

BMW was the first manufacturer in Europe to introduce a navigation system in 1994, making data outside the vehicle accessible to the driver. This was one of the foundation stones for the development of BMW ConnectedDrive. While in the past the interaction between the three areas of driver, vehicle and environment depended entirely on the adaptability of the individual, BMW ConnectedDrive shifts the burden clearly away from the driver by opening up innovative technical possibilities in the field of telematics. BMW ConnectedDrive links the car to the outside world and the situation on the road so as to provide the driver with as much as information as required and desired, as individually and as ergonomically as possible. A fundamental principle of the BMW ConnectedDrive concept is Warn rather than intervene: the driver always retains the responsibility for his vehicle. BMW ConnectedDrive connects the strengths of the driver with those of the technology. In concrete terms, this means that BMW ConnectedDrive offers the driver as much information and assistance as desired, according to the individual situation. What BMW ConnectedDrive has to offer: BMW Assist, BMW Online, BMW TeleServices and BMW Tracking. BMW ConnectedDrive is a dynamic concept in every way. The constant further development of services offers an increasingly high level of convenience in terms of mobility and information. Depending on the country concerned, BMW ConnectedDrive currently consists of the products BMW Assist, BMW Online, BMW TeleServices and BMW Tracking. BMW Assist: get to your destination faster, more reliably and more conveniently. (Description refers to the offer available in Germany. The portfolio of services may differ in other countries in which BMW Assist is available). The services available to the driver are emergency call with automatic position finding, extended traffic information, a comprehensive information service and the
BMW Media Information 7/2008 Page 37
interactive communication channel My Info incl. Send to Car functions services which support the driver during travel, at his current location or at his destination. The BMW ConnectedDrive remote function enable the doors to be locked and unlocked worldwide by telephone as well as vehicle positioning finding to the nearest metre. If the worst comes to the worst: emergency call with automatic position finding. The Enhanced Emergency Call offered by BMW ConnectedDrive provides the facility for rescue teams to receive detailed information on the type of collision and potential risk of injury even before they arrive at the site of the accident, enabling them to preparing the appropriate medical care for those involved in the accident well in advance. As of March 2008, data transmitted to the BMW Call Centre includes not only the exact position of the vehicle and the mobile phone number, vehicle type and vehicle colour but also the data collected by the vehicle sensors. The activation or non-activation of restraint systems fitted in the vehicle is registered as well as the occupation and belt status of the front seats. In addition, head-on, rear-on, side-on and even multiple collisions can be identified and differentiated. A vehicle roll-over can also be recorded and reported. In addition to automatic activation, the driver or front passenger can also activate the emergency call manually, with an immediate connection provided to the BMW Call Centre. The BMW emergency call has been able initiate rapid assistance in over 25,000 cases to date. Avoid tailbacks: quite simply with Traffic Info plus. Another service provided by BMW Assist is Traffic Info plus (V-Info+). V-Info+ gives the driver more up-to-date, more detailed and more comprehensive information on the current situation on long-distance roads than that provided by conventional radio traffic bulletins. The service forwards the relevant traffic bulletins and information such as automatically calculated tailback lengths and delay times to the navigation system, which in turn offers recommended detours. Just in case: the telephone information service. The telephone information service includes more than 35 million entries from the yellow pages and telephone directory. The BMW Assist information service also includes additional information such as restaurant ratings, emergency pharmacies, cinema listings, current flight information and the possibility of making hotel reservations. When the driver selects the menu item Information service, he is put through to the BMW Call Centre. At the same time, the vehicle automatically determines its own current position. In this way, the Call Centre staff member can identify information relevant to the position

The intelligent all-wheel drive system BMW xDrive: Variable, dynamic, supreme now also in the BMW 320d xDrive.
BMW as the worlds most successful provider of all-wheel drive vehicles in the premium segment. Intelligent all-wheel drive system BMW xDrive even more precise due to controlled brake intervention with torque compensation. BMW xDrive now available for five engine types new: BMW 320d xDrive.
BMW has established itself worldwide as the market leader for all-wheel drive vehicles in the premium segment. No other all-wheel drive system enhances driving dynamics, traction and stability like BMW xDrive. The outstanding quality of the electronically controlled and variable power distribution between front and rear wheels is impressively brought to bear in the vehicles fitted with BMW xDrive both on difficult terrain and on surfaced roads. The first BMW all-wheel model went on the market in 1985: a BMW 325iX. Since then BMW xDrive has continuously increased in importance in the model range of the BMW 3 Series. The all-wheel drive system is available for the Saloon and Touring models as well as the BMW 3 Series Coup. For the first time, the new BMW 3 Series now also offers the option of a 4-cylinder model fitted with the intelligent all-wheel drive system. The new BMW 320d xDrive combines outstanding efficiency with superior driving dynamics and traction qualities. For the Saloon, Touring and Coup models of the BMW 3 Series there are three petrol engines and two diesel engines available in combination with 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. BMW xDrive: variable, precise power distribution and fast response in every situation on the road. The electronically controlled, permanent all-wheel drive system BMW xDrive offers an incomparable degree of comfort, traction and agility over all road surfaces with its situation-based distribution of drive torque between the front and rear axles. BMW xDrive acquires its status as an intelligent all-wheel drive system from the fact that it always directs drive power to the axle whose wheels have the best contact with the road surface, by means of a transfer
BMW Media Information 7/2008 Page 43
gearbox with an electronically controlled multi-plate clutch which operates precisely according to the prevailing situation. The system responds with outstanding accuracy and speed to any change in the driving situation. In normal driving situations, BMW xDrive distributes drive torque to the front and rear axle at a ratio of 40:60. Here, sensors constantly measure slip at the wheels of the front and rear axle. Within a fraction of a second, the system is able to vary the ratio of power distribution. Unlike conventional all-wheel drive systems, BMW xDrive also responds in anticipation, not waiting until a wheel actually starts to spin. The vehicle is thus stabilised before the driver registers any need for action. For even more precise control, the computer units of the driving stability regulation system Dynamic Stability Control (DSC) and the xDrive are networked with one another in the Integrated Chassis Management (ICM). This high-performance electronic control system enables the drive and chassis functions to harmonise within a fraction of a second so that maximum stability and performance are available in every situation on the road. Even in the event of sudden changes in conditions such as changes in the road surface, spontaneous steering manoeuvres, abrupt acceleration or braking the ICM responds precisely by activating the DSC and xDrive actuators, optionally also those of the Active Steering. The type and extent of such interventions is always such that not only driving stability but also dynamic performance are maintained at the highest possible level. Optimised supremacy due to measured brake intervention with torque compensation an evolution of DSC. With these capabilities, xDrive enhances driving dynamics because it detects any tendency to oversteer or understeer early on and counteracts effectively. The close interaction between DSC and xDrive via ICM also enables carefully measured brake intervention with torque compensation: this effectively anticipates any tendency to understeer on slippery surfaces or when taking a corner at speed. As soon as the front wheels push excessively towards the outside, the inside rear wheel is selectively braked via the DSC control function. The loss of propulsion thus brought about is compensated for by an increase in drive power so that corners can be taken more precisely even on slippery surfaces.

The history: From pioneer to role model for dynamic performance in the medium category.
1975: premiere for a new vehicle category. Ongoing progress: the BMW 3 Series as a bearer of innovation. Setting the benchmark in the segment over five model generations.
To be exact, the history of the BMW 3 Series began in March 1966 with the presentation of the BMW 1600-2 at the Geneva Salon. This was the starting signal for what was then the smallest BMW model series: a 2-door Saloon with a sports-style design and an engine with a slightly coup-like character as well as the classic engineering features of the engine at the front and rearwheel drive. The BMW 3 Series has always remained faithful to this fundamental principle and acquired its new designation at its premiere in 1975 as a new vehicle category within the BMW model architecture. Over five model generations, the BMW 3 Series has always remained faithful to its character as an agile, smart automobile with an engine of excellent quality and indeed went on to become the original role model for this type of vehicle. But it has also repeatedly been a pioneer of technological progress and has set the benchmark in its segment. The first generation: the 3 Series BMW instantly becomes an original. While the first generation of the BMW 3 Series (1975 to 1983) had a single body shape and initially four later five engine types with up to 143 bhp in the BMW 323i, the number of versions and engine types was to multiply significantly over the next 30 years. The second generation: variety of versions. The second generation (1982 to 1994) brought with it a second body version with the first four-door model, a third body version with the Convertible and a fourth with the Touring (at the time deliberately spelt in lowercase letters), as well as the first all-wheel drive version. In addition to powerful 4-cylinder and 6-cylinder petrol engines with up to 171 bhp, an 86 bhp diesel engine was also offered for the first time. As a high-performance version, BMW Motorsport GmbH contributed the M3 initially with 200 bhp, later 238 bhp. The third generation: the advance in design. The third generation (1990 to 2000) started out with a completely new styling, the body also increasing notably in size to allow for a more comfortable and safer passenger cell. In the engine area the use of 4-valve technology brought

about a significant increase in output: the range now went from 100 bhp in the BMW 316i to 193 bhp in the BMW 328i Coup. As a fifth body version alongside the Saloon, Coup, Touring and Convertible the BMW 3 Series compact was now introduced which for the first time offered an 87 bhp engine running on CNG gas in addition to petrol and diesel versions. The fourth generation: a firework display of innovations. In May 1998 the fourth BMW 3 Series was launched initially as a 4-door Saloon once again, with increased comfort, safety and performance. And it did so with a bang: the BMW 320d was the first BMW with a direct injection engine, overshadowing everything else in its category with an output of 100 kW/136 bhp, a top speed of 207 km/h and a fuel consumption of 5.7 litres. The other engine versions were equally groundbreaking: the basic model was the BMW 318i with 118 bhp, followed by the BMW 320i with 150 bhp and six cylinders, the BMW 323i with 170 bhp and finally the BMW 328 with 193 bhp. And these engines had many new features to offer: inside the 1.8-litre 4-cylinder engine there were two balancing shafts which improved the noise level inside the car by up to 10 dBA as compared to the predecessor model. The technologically most prominent measure in the 6-cylinder engines was the introduction of Double Vanos to provide a fuller torque curve and further reduce the level of pollutants in the exhaust gas. With the combination of rear-wheel drive, an ideal weight distribution of 50:50, the electronic regulation systems ABS, ASC+T and the dynamic stability control system DSC III, the chassis of the BMW 3 Series moved the benchmark up to a new level. A highlight in this package was the ITS head airbag, a tube-like structure hidden in the door frame next to the driver and front passenger ensuring significantly improved head protection over previous systems. But it was not only these spectacular new features which allowed the 3 Series to advance into regions otherwise reserved for the luxury performance segment. BMW also introduced the new Car Memory and Key Memory as standard features, as well as offering the multifunction steering wheel, rain sensor and Steptronic as optional extras. From autumn 1998 there followed integrated childrens seats, RDC, xenon light, on-board monitor with navigation system, TV and extended on-board computer. In addition to the Saloon, the highlights in the model range of the fourth generation were the new versions of the Coup, Touring, Convertible and compact, with the BMW 330d as a special highlight. With a rated torque of 390 Nm from 1,750 rpm, the 6-cylinder diesel was a sheer power package with extreme

10. The new sports automatic transmission with double clutch in the BMW 3 Series Coup and the BMW 3 Series Convertible: Constant pulling power for maximum dynamic performance.
New 7-speed sports automatic transmission with double clutch, shifts without any interruption of traction. Increase in sprint capacity, reduced fuel consumption and exhaust emissions. Premiere in the BMW 335i Coup and BMW 335i Convertible.
BMW presents a enthralling alternative to the 6-speed manual transmission which fascinates drivers with sporty ambitions while at the same time providing all the convenience of an automatic transmission. The new 7-speed sports automatic transmission with double clutch (DKG) now available in the BMW 3 Series enables even more dynamic acceleration and contributes to the reduction of fuel consumption and exhaust emission levels: with these properties it represents the sportiest embodiment of the development strategy BMW EfficientDynamics. The new sports automatic transmission gives the driver the choice between automated shifting and manual gear selection. In both cases, the 7-speed double clutch transmission shifts without interruption of traction, thus enhancing both sporty drive response and shift comfort. The result is a unique combination of further increased dynamic performance when shifting manually with the comfort provided by automatic transmission and at fuel consumption and exhaust emission levels which are even lower than those of manual transmission vehicles. A newly designed shift lever is provided in the central console to operate the system. It is clearly differentiated from a conventional automatic transmission selector lever in its shape and its integrated display for the selected shift program; what is more it does not relay commands for the shift program selection or gear change by means of a mechanical connection but electronically. Alternatively, the driver can carry out manual gearshifts using so-called shift paddles which are attached to the steering wheel. The power transmission system developed for the BMW 3 Series is designed for especially powerful and high-revving engines in vehicles with rear-wheel drive. Consequently its debut is in the models BMW 335i Coup and BMW 335i Convertible, where it is featured in combination with the 225 kW/306 bhp in-line 6-cylinder engine with Twin Turbo and High Precision Injection.

Sports automatic transmission with double clutch in the BMW 3 Series: faster but more economical, too. The gradation of the 7-speed transmission ensures a constant increase in speed which is continued at an optimum follow-up engine speed after each shift. No time is lost while changing gear because there is no interruption of traction. The sports automatic transmission completes entire gearshifts within a period of time which in manual transmission vehicles would at most be sufficient to open the clutch. The result: outstanding acceleration rates. The BMW 335i Coup with sports automatic transmission completes the sprint from zero to 100 km/h in just 5.4 seconds 0.1 seconds faster than the model fitted as standard with 6-speed manual transmission (5.5 seconds) and 0.3 seconds faster than the BMW 335i Coup with the previously available 6-speed automatic transmission. The benefits of shifting without interruption of traction and the small steps in engine speed are not only reflected in driving dynamics but also in ride comfort and efficiency. Excellent acceleration goes hand in hand with outstanding shift comfort in urban traffic. The swift, jerk-free change of gears makes for exceptionally harmonious acceleration manoeuvres. The unavoidable load change reactions associated with conventional transmission systems are completely eliminated: even when driving with maximum dynamic performance, a level of ride comfort is achieved which was not previously feasible. Due to the swift and precise selection of the ideal gear, the efficiency of the vehicle is further optimised. The BMW 335i Coup with sports automatic transmission achieves an average fuel consumption in the EU test cycle of 8.8 litres per 100 kilometres. The average fuel consumption of the BMW 335i Convertible with sports automatic transmission is 9.1 litres per 100 kilometres. This is equivalent to a reduction in fuel consumption of up to five per cent as compared to the equivalent models with 6-speed manual transmission and with 6-speed automatic transmission. Three operating modes, new gear lever, manual gearshift using paddles at the steering wheel. The newly design shift lever for the sports automatic transmission with double clutch serves both to change between shift modes and to relay shift commands for manual gear selection. Its shift layout is the same as that of a regular automatic transmission, though the lever always returns to its original position after activation. The sports automatic transmission with

BMW Media Information 7/2008 Page 50
double clutch is not operated mechanically but by means of electrical signals. The current shift program or gear position is shown in the display panel of the shift lever and in the instrument panel. The new sports automatic transmission with double clutch ensures faster and more comfortable gear changes in three operating modes. Automated gearshifts are made both in the comfort-oriented D mode and in the sportyoriented S mode. The S mode is activated by shifting the lever to the left. An additional shift of the selector lever to the front () or rear (+) activates the manual shift mode. The driver can opt for manual gearshift at any time, both in the D mode and the S mode. The driver simply makes the first shift using the paddles at the steering wheel. The instrument panel then shows an M symbol in conjunction with the relevant gear, instead of the S symbol. Maximum dynamic performance: sports button and Launch Control. When accelerating in automated shift mode, the gear shifts S mode are undertaken significantly later in S mode than in D mode so as to exploit engine torque more fully. In addition, the shift characteristics of the sports automatic transmission with double clutch can be influenced by using the sports button in the central console. By pressing this button, both the accelerator pedal and the gear shift response are given a sportier profile. This creates a perceptibly power-oriented acceleration response with faster gearshifts, both in the D and the S mode of the sports automatic transmission. Gearshifts are effected by means of faster closing of the clutch with sporty feedback to the driver. The combination of S mode and activated sports button thus results in gearshifts at much higher engine speeds and a highly sporty shift response. The double clutch transmission is also in contact with the engine management system when it comes to downshifts. Clutch engagement is very gentle so as to prevent any unwanted braking of the rear wheels. If the transmission electronic system detects a very large jump in engine speed at a change of gear for example in the case of an extremely sporty driving style and sudden application of the brakes torque relay to the next gear is delayed until the engine speed regulator has increased engine speed accordingly. This intermediate throttle application further enhances drive stability as well as intensifying the driving experience. In manual mode the sports automatic transmission with double clutch also provides a Launch Control which enables a standing start with maximum acceleration, adapted to the prevailing conditions in terms of tyre state, road surface and load. The requirement for the use of Launch Control is activation of Dynamic Traction Control (DTC), which raises the threshold response of the Dynamic Stability Control (DSC) function, and of the sports button.
