THE NEW 6th GENERATION BMW 5 SERIES UNVEILED IN MUNICH23.11.2009The Perfect Symbiosis of Modern Design and Dynamic Performance.Woodcliff Lake, NJ – November 23, 2009, 2:00pm EST… The world debut of the new BMW 5 Series Sedan marks the epitome of modern design and driving pleasure in the world of premium midsize sedans. Through its athletic and executive looks, driving dynamics typical of BMW, and innovative comfort and safety features, the sixth generation of BMW’s executive express accurately reflects the standards upheld by the world’s most successful manufacturer of premium cars. Design: charismatic and athletic. Within the interior, precise functionality and a fresh ambience come together in perfect harmony, unmistakable style, and clear orientation to the driver. Driving experience: benchmark dynamics and exceptional
comfort. At launch, the new BMW 5 Series Sedan will be available with one V-8 and one inline-6 gasoline engine. The top-of-the-range BMW 550i arrives with BMW’s “reverse-flow” V-8 engine featuring twin turbochargers and High Precision direct injection for maximum output of 400 hp. The new inline-6 of the BMW 535i features a single twin-scroll turbocharger, High Precision direct injection, and, for the first time, VALVETRONIC throttle-less intake technology. It delivers a maximum output of 300 hp and 300 lb-ft. The 535i and 550i will be available with a choice of 6-speed manual transmission, BMW’s new 8-speed automatic transmission, or new “Sport Automatic” 8-speed. Later, the BMW 528i will debut with a 240 hp inline-6 featuring lightweight magnesium-aluminum construction and VALVETRONIC throttle-less intake technology for efficiency and unparalleled responsiveness. BMW EfficientDynamics: BMW 5 Series increasing the lead. Innovative driver assistance systems. Joint development and production together with the BMW 7
Series. Joint production of the BMW 5 Series Sedan and the BMW 7 Series at BMW Plant Dingolfing, together with the extensive use of shared components, ensures highly efficient production with the highest standards of quality. The New BMW 5 Series In Detail Exterior: Dynamic proportions in perfect balance. The entire silhouette is superbly balanced, providing a clear indication of the near-perfect front-to-rear weight distribution for all engine variants. Measuring 2.97 meters or 116.9”, the wheelbase of the new BMW 5 Series is the longest in the car’s segment, while the sculptural design again distinctive of BMW provides a smooth flow of lines from the front along the side to the rear, creating a body where everything fits together as if out of one mould. Charismatic front, elegant side, muscular rear. In conjunction with the BMW Adaptive Xenon headlights (optional on 528i), the daytime running lights incorporate quite unmistakable LED corona rings, while the direction indicators moved far to the outside are made up of ten LED units each. As a final highlight, an LED focus light marks the upper edge of each headlight unit. Above the striking contour line running along the car at the height of the door openers, a slightly flared shoulder surface, together with the coupe-like roofline and the stretched window surface, gives the glazed section of the passenger cell a light and stretched look despite its size. Further down the body, concave modeled surfaces create lively light and shade effects emphasizing the sporting character of the sedan. Greater curvature around the rear wheel arches, finally, bears clear testimony to rear-wheel drive typical of a BMW of this kind. The dynamic lines of the car are further enhanced by the strikingly compact counter-swing at the bottom of the C-pillar. Featuring the smallest radius at this point ever to be seen on a BMW sedan, this re-interpretation of the typical Hofmeister kick underlines the stretched silhouette of the car and gives the passenger cell a light and low appearance. Running parallel to one another, the contour and sill lines rise up dynamically, the former stretching out from the front wheel arch all the way to the rear lights to create the elegant and dynamic look of the car from the side. The sculptural shape typical of a BMW established in this way makes the side sections and the rear end literally flow into one another. The contour lines continue into the contours of the rear light clusters and finally come together above the license plate. Seen from the rear, the new BMW 5 Series Sedan also stands out through the concave surface between the contour line and the wheel arches giving the body a distinctly recognizable waist. The flared wheel arches and the horizontal breakdown of the rear end, in turn, strongly emphasize the powerful stature of the sedan, the wide track and the wheels ending flush with the wheel arches further enhancing this impression. The L-shaped rear light clusters again reflect the typical look of a BMW and provide that unmistakable night design. Three rows of LED lights form the look of homogeneously glowing bodies again quite characteristic of BMW. And last but not least, the direction indicators and brake lights also come in LED technology. Interior Design As in all BMWs, well-researched ergonomics allow for optimum operation of driving controls and other functions. All displays, knobs and buttons serving comfort functions are situated centrally for use by the driver and front passengers; controls for the driver’s use only are to the left of the steering wheel, on or near the steering wheel, or on the front center console. The steering wheel has power tilt and telescopic adjustment and tilt-away for exit and entry; and of course both front seats come standard with 10-way power adjustment including head-restraint height. The seating position has been improved over the former model both front and rear, with knee-room on the rear seats of the new BMW 5 Series Sedan up by 13 millimeters or 0.5”. Luggage compartment capacity is 520 litres or 18.2 cubic feet, and the folding rear-seat backrest available as an option provides greater flexibility in enlarging the car’s transport capacities. In addition to its 40:60 split, the rear-seat backrest also comes with through-loading and, as yet a further option, a ski-bag for additional convenience. Instrument panel in Black Panel technology. 4th-generation iDrive: Intuitive, powerful and fast. The instrument cluster interacts in new ways with the iDrive control display and the available Head-up Display. According to selected function, users can call up phone numbers or radio stations via the steering-wheel controls. The cluster display also augments iDrive’s optional Navigation display with road-realistic directional instructions, helping the driver to change lanes or negotiate a complicated intersection. If the optional Head-up Display is activated, the relevant directions appear there. Materials and colors: enhancing the elegance. Dark Burl Ash wood trim interior trim is standard, appearing in sweeping expanses on the dash, doors and front center console; Ash Anthracite (gray tone) and another distinctive wood called Fineline Matte are optional. The center console comes in two variants: On cars with a manual gearbox the console is split into two sections, the black surface surrounding the gearshift lever and the buttons on the optional Driving Dynamics Control oriented towards the driver. A key holder has been placed between the gearshift lever and the climate controls. On models with automatic transmission, the space between the electronic gear selector lever and the climate control unit offers enough room for two cupholders and a key holder. A further storage compartment is located behind the iDrive Controller (where there is another cupholder on models with a manual gearbox). Powertrain: The essence of BMW EfficientDynamics. The 550i is powered by BMW’s stunning 4.4-liter, 400-hp twin turbocharged V-8 engine. Compared to BMW’s earlier, normally aspirated V-8, displacement is reduced from 4.8 to 4.4 liters, and incorporates twin turbochargers with High Precision direct injection. In quantitative terms, the new engine delivers its 400 hp over a range from 5500 to 6400 rpm. Maximum torque is 450 lb-ft, available over the extremely broad range of 1800 to 4500 rpm. Aside from the dramatic thrust that drivers will notice subjectively, the objective data are dramatic too: 0-60 mph is estimated to be in just 5.0 seconds (preliminary) and a top speed when equipped with the Sport Package of 150 mph. For models without Sport Package the maximum speed is limited to 130 mph. Through its unique reverse-flow layout, the 550i’s V-8 engine is able to achieve higher output without correspondingly higher fuel consumption. In technical terms, the approach involves some very new design details. For the first time, twin turbochargers and the exhaust-cleansing catalytic converters are placed between the V-8’s two cylinder banks. In turn, this required the exhaust camshafts and valves to be inboard so that the path from cylinders to turbochargers (which are driven by exhaust gas) would be kept short. A key benefit of this layout becomes a more compact engine package. This is the reverse of a traditional V-8 layout, and opens a new era of V-8 engine development potential. BMW’s newest gasoline inline-6 engine will be the powerplant for the new 535i Sedan. It features a single, twin-scroll turbocharger and 3.0 liters of displacement. In addition to High Precision direct injection, the new engine is the first BMW inline-6 to be equipped with both turbocharging and BMW’s VALVETRONIC throttle-less intake technology. The combination of these BMW EfficientDynamics technologies delivers improved throttle response from idle to redline, reduced fuel consumption, and substantially reduced emissions. The new engine is rated at 300 hp at 5800 rpm and 300 lb-ft of torque. The torque peak is notable for its incredible accessibility: the full 300 lb-ft is available from 1200 rpm – 5000 rpm. Playing a supporting role: innovative new 8-speed automatic
transmission. Technically speaking, this new automatic’s attributes have been achieved via an innovative concept that provides the two additional ratios (7 and 8) with no increase in bulk or weight. In an arrangement not heretofore employed in an 8-speed automatic, four planetary gearsets and five clutch packs are controlled in a way that no more than two of the five clutch packs are freewheeling at any given time. The modest increase in the number of mechanical elements allows the new transmission to achieve unusually high efficiency: the so-called “gearing efficiency” is higher than 98% in all eight gears. In 6th gear, it’s highest of all because that is direct drive, with no gearing reduction at all. Combine this with reduced friction and the ability to keep the torque converter “locked up” more of the total driving time, and the transmission becomes very much a part of the new 5 Series’ overall efficiency concept. Two additional gears mean threefold progress: quicker shifts, greater
smoothness, enhanced efficiency. And for the same reason, faster shifts are a further benefit because only one clutch pack is disengaged to shift up or down by one or two gears. On the other hand, downshifting more than two gears is accomplished as a direct shift. For example, a downshift from 8th to 2nd gear is made with only one clutch pack disengagement, and thus occurs without stepping down through the intermediate gears. Thus at one instant the driver can be enjoying the quiet, fuel-efficient low rpm of 8th gear, and in the next instant getting maximum acceleration. Manual Transmissions: Continuing a BMW tradition The 535i and 550i Sedans will be offered with a 6-speed manual transmission in the United States, providing a level of driver involvement unique in the segment. Brake Energy Regeneration: an energy-saving innovation. Conventionally, a car’s alternator runs continuously and thus is always charging the vehicle’s battery. In the new 5 Series, it charges only when the vehicle is decelerating or braking; otherwise, it freewheels and draws virtually no power from the engine. An electronically controlled clutch, similar to that used with the air-conditioning compressor, is used to engage and disengage the alternator. Accommodating the less-frequent charging is a special, more powerful vehicle battery that can satisfy the vehicle’s high electrical demands without access to continuous charging. The battery uses a technology called “glass mat,” in which its internal plates are separated with saturated absorbent glass-boron silicate rather than the usual liquid electrolyte. This construction sharply reduces the battery’s conversion of charging energy to heat, and can provide the necessary electrical power for longer periods between charges. 1. Chassis engineering: Front suspension: a new multi-link system. Now this system has made its debut in the automobile side of BMW’s vehicle line, first in the new 7 Series in 2009 and now in the new 5 Series. In place of the strut, this new system has an upper lateral A-arm. The double-pivot lower arms are retained, so that on each side there are three links or arms. While the two lower arms preserve the double-pivot strut system’s advantages, the new upper arm facilitates the system’s handling and riding comfort by relieving the strut of its geometric duties. Among the strengths of the double-pivot system
are: The 5 Series sedan’s multi-link configuration adds further
virtues: In keeping with another BMW tradition – aluminum suspension
components to reduce unsprung weight and thus improve road adhesion
and riding comfort – most major elements of the new front
suspension are aluminum: Further reducing unsprung weight are the front brake calipers, which
are of composite aluminum/cast-iron construction. The suspension
subframe, which is sprung weight but important in terms of front/rear
weight distribution and total vehicle weight, is also of aluminum. Yet
more advantages are found in certain details: Rear suspension. The Integral suspension concept has been in use for some years in BMW automobiles, appearing currently in the 5 and 6 Series in 4-link form. With one additional link per side, the Integral V (5-link) system moves one step closer to perfection in its combination of handling response, road adhesion and riding comfort. Here too, most major elements are aluminum, and the rear suspension subframe is also of aluminum. This complex multi-link system controls rear-wheel geometry very precisely, minimizing unwanted effects under load changes (such as lifting off the accelerator while cornering, or hard acceleration and braking) and achieving a comfortable, supple ride. In the new 5 Series, it adds yet another capability via optional Integral Active Steering as introduced on the 2009 BMW 7 Series. Precise and efficient: EPS Electric Power Steering making its debut
in the BMW 5 Series. Precise, smooth and harmonious set-up of the steering with the feedback typical of BMW ensures maximum steering accuracy at all times. In the Sport+ mode of Driving Dynamics Control and with DSC switched off, the degree of steering forces is slightly increased in accordance with the style of motoring desired. EPS serves to control steering feedback from the system with particular precision. At the same time EPS comes as standard on the new BMW 5 Series Sedan with Servotronic gearing steering assistance to the speed of the car. When parking and steering at low speeds, for example, the driver hardly has to make any effort, while at higher speeds power assistance is intentionally reduced for optimum contact to the road and in the interest of well-balanced directional stability. A further point is that EPS eliminates bumps coming from the steering and any other adverse vibrations very effectively. And by evaluating dynamic driving signals in an appropriate process, EPS gives the driver authentic steering feedback particularly under very dynamic driving conditions. Integral Active Steering: greater agility in town, enhanced comfort
& stability during quick lane changes. At the front wheels, Integral Active Steering electronically varies the steering ratio (the number of degrees the steering wheel must be turned to achieve a 1º steering angle at the front wheels) on the basis of vehicle speed and other driving conditions. This reduces the steering-wheel movements required for parking maneuvers, U-turns and sharp corners. Also with Integral Active Steering, the rear wheels are steered up to a maximum of 2.5? via a servo motor acting on the track rods. At low speeds, they are steered oppositely to the front wheels, reducing the turning circle by approximately 0.5meters (1.6 feet). At higher speeds (above 60kmh / 35mph), the rear wheels steer in the same direction as the fronts, enhancing stability. Additionally, the rear-seat passenger comfort is improved thanks to reduced lateral forces in highway lane-change conditions. The most sporting 5 Series Chassis to date. Electronic limited-slip differential Intelligent driving dynamics: Integrated Chassis Management and
FlexRay For this extremely sensitive and powerful networking of functions, the 5 Series shares an electrical architecture with the 7 Series and 5 Series Gran Turismo that employs FlexRay data-transmission technology. Developed by a consortium of which BMW is a leading member, FlexRay achieves heretofore unheard-of communication speed, some 20 times that previously possible. In the new 5 Series, up to 16 electronic control units can be networked; in no other competitive automobile can longitudinal, lateral and vertical vehicle motions be so precisely monitored and influenced. BMW was the first motor-vehicle manufacturer to offer FlexRay technology in production vehicles; it made its debut in the current BMW X5. Generously dimensioned disc brakes with composite front
rotors. Reduced rotor deformation under hard braking is the other benefit. This means fewer tendencies of the brakes to vibrate when hot, and reduced likelihood of rotors cracking under extreme heat conditions. The 5 Series brake system is supported by the comprehensive functions of Dynamic Stability Control (DSC). These include antilock braking (ABS), Automatic Stability Control (ASC), Cornering Brake Control and Dynamic Brake Control; each of these functions contributes to vehicle stability and some of them do so specifically during braking. Other braking enhancements via DSC include Brake Fade Compensation, which compensates for loss of braking power (fading) under hard or repeated brake use; Brake Standby, which snugs the brake pads up to the rotors upon sharp deceleration to reduce inherent lag time in brake application; and Brake Drying, which brings the pads to the rotors periodically during wet-weather driving to keep the brakes ready. Automatic Hold, a function included in the 5 Series, 7 Series, X5 and X6 models, holds the brakes for an indefinite time when the vehicle is stopped anywhere, preventing rollback or creep; it can be activated or de-activated by the driver with a console button. Wheels and tires Ordering the optional Sport Package will add larger alloy wheels and sportier, summer-performance tires for all models. More information will be available prior to the on-sale date. Innovative features The BMW Parking Assistant: extra comfort ensured through fully
automatic steering and optimum user guidance. The BMW Parking Assistant supports the driver from the start in choosing appropriate parking space. Ultrasound sensors integrated in the side indicators measure the length and width of possible parking spaces when travelling at a speed of up to 22 mph. The system thus looks for parking spaces exceeding the length of the car by at least 1.20 meters or 47 inches. When the BMW Parking Assistant is not activated, this measuring process continues in the background without emitting any particular signals to the driver. But as soon as the driver comes to a stop and shifts into Reverse, the iDrive Control Display informs the driver of a suitable parking space by presenting an appropriate symbol. Once the driver has activated the system, all parking spaces sufficient for the car are presented while driving past. In both cases the driver simply has to press the Controller to use the Parking Assistant. From this point, all the driver has to do is operate the gas and brake pedals and supervise the actual driving manoeuvre, while the Parking Assistant moves the steering wheel appropriately in order to back up precisely into the parking space available. The driver also receives functions to guide him/her though the parking process. Acoustic and visual messages from Park Distance Control and from the Top View system help the driver in adjusting the distance from other vehicles or obstacles ahead of or behind the car in the parking space chosen. Innovative Top View and Side View features: enhanced proximity
awareness for maneuvering. Top View provides an even more comprehensive and complete picture of the car and its surroundings. In addition to the back-up camera and the PDC sensors, Top View uses two cameras in the side mirrors, and combines all three images through a central processor. This provides an overall picture presented in the Control Display showing both the car and its surroundings from a bird’s eye perspective. This clear overview enables the driver to manoeuvre precisely even in confined spaces. Side View provides specific assistance for the driver in metropolitan driving situations. Side View uses two cameras integrated in the front bumper and serves to monitor traffic moving crosswise to the vehicle. The images obtained in this way are likewise transmitted to the Control Display and provide an early overview of traffic conditions to the left and right of the car, particularly when pulling out of a narrow or unclear driveway. Innovative combination: Frontal Collision Warning with brake
activation function combined with Active Cruise Control and
Stop & Go. Active Cruise Control with Stop-and-Go is optional. In addition to the speed-maintaining, acceleration and deceleration functions of the standard cruise control, ACC can adjust the BMW driver’s speed according to traffic conditions via radar sensors at the front of the vehicle. The Stop-and-Go function can bring the vehicle to a complete stop if traffic calls for it. After a stop of more than 3 seconds, the driver must step on the accelerator or select Resume to accelerate back to the set speed or whatever speed the radar sensors allow. When equipped with Active Cruise Control, the new BMW 5 Series Sedan has a subsystem called Collision Warning which can apply the brakes. Collision Warning with its brake activation function triggers an alarm in two stages. The pre-warning is an optical message presented as a red car symbol in the instrument cluster and, when fitted, also in the Head-Up Display, warns the driver of the closing rate to the vehicle in front. As soon as this symbol appears, the Brake Standby function on DSC Dynamic Stability Control is activated. This ensures rapid build-up of full brake pressure in an emergency. The second stage in the collision warning process is activated in the event of an imminent collision. When the driver is required to intervene very quickly, the system sends out an acute warning – in this case not only an optical, but also an acoustic message. It also initiates the braking process required, slowing down the car with stopping power of up to 3 meters/sec2 for a maximum of 1.2 seconds. Brake Standby function is again activated, preparing maximum brake system pressure to achieve the shortest stopping distance possible. Active Blind Spot Detection Should the driver set the direction indicator nevertheless, indicating that s/he is about to change lanes, the LED signal in the light will warn the driver by flashing on and off. The driver will also be warned by discreet but unmistakable vibration of the steering wheel. Lane Departure Warning: camera-based system warns the driver of
unintended lane departure even in the dark. The camera incorporated in the Lane Departure Warning system monitors the road markings on at least one side of the car, a control unit calculating the position of the vehicle in relation to such road markings. The camera is able to look ahead about 50 meters or 165 feet, and is also able to respond appropriately in bends or on narrow lanes. The system even works in the dark once the headlights have been switched on, making it helpful under everyday driving conditions. Sophisticated headlight technology with intelligent
control. The optional Automatic High-Beam feature in the new BMW 5 Series offers additional safety when driving at night. Taking current driving conditions into account, this system switches the high beam on and off automatically as required, consistently giving the driver optimum visibility and at the same time relieving him of the chore to constantly monitor the high beam in the case of oncoming traffic. Processing images generated by a camera integrated in the interior mirror, the Automatic High-Beam feature recognizes vehicles driving ahead in the same direction up to a distance of approximately 400 meters or 440 yards and oncoming vehicles up to a distance of about 1,000 meters or 1,100 yards. A further feature is that the high-beam is switched off automatically as soon as the surrounding light reaches a certain level of intensity and is therefore bright enough. To avoid collisions from behind, the new BMW 5 Series Sedan, like other models from BMW, feature special Adaptive Brake Lights introduced by BMW as the world’s first manufacturer to offer such a feature. When applying the brakes particularly hard and when ABS is activated, drivers following from behind are alerted by the larger brake lights. Greater safety when driving at night: BMW Night Vision with
Pedestrian Detection. This presentation on the screen is supplemented in the case of BMW Night Vision by the automatic detection of persons on or next to the road. To provide this function, the video data is analysed by a control unit using intelligent algorithms to find pedestrians and cyclists potentially on collision course with the car. Once the system detects a possible risk involving such persons, the driver is warned by the Control Display and the optional Head-Up Display. This warning is restricted to pedestrians and cyclists who, on account of the speed, steering angle and yaw rate involved, are on a calculated collision course with the vehicle. Body and safety. This optimization of weight comes together with a further increase in
passive safety and is possible through the appropriate use of
high-strength multi-phase steel, ultra-high-strength hot-moulded
steel, and aluminium. The torsional stiffness of the vehicle as a function of its footprint and weight has also been significantly improved. Spring supports made of pressure-cast aluminium enhance the driving dynamics of the new BMW 5 Series in two respects, making the entire front section even stiffer and, through their low weight, further improving the overall balance of the car. For the first time the doors of the BMW 5 Series Sedan are made of aluminium, reducing weight by approximately 23 kg or 50 lb versus a conventional structure. The front side panels, the hood and a large number of the front and rear axle components are also made of this particularly light metal. Exemplary occupant protection. In the interior, 2-stage front airbags, seat-mounted side-impact airbags and curtain-type, front-to-rear head protection are all standard equipment, controlled according to crash type and severity for optimum effect. Airbags that are not needed for the impact at hand are not deployed, yet remain ready to deploy in case of a secondary impact. The power tilt/telescopic steering column includes a robustly dimensioned deformation section, improving its ability to protect the driver from structural intrusion into the cabin. All seating positions are equipped with 3-point safety belts; all have force limiters, the front ones also adding automatic tensioners plus pre-tensioning during emergency braking. For protection against head and neck injuries in a rear-end impact, the front seats include active head restraints, which deploy up to 2.36 in. forward and 1.57 in. upward as required – all between the time the rear impact begins and when the occupants’ heads would be thrown rearward. The rear outboard seating positions are equipped with LATCH (Lower Anchors and Tethers for Children) for securing a child restraint seat.
