BMW has launched its medium size limousine today at 8PM CET. The car was unveiled at the Munich central stadium. At first glance, 2010 BMW 5 Series seems to be more sporty than the previous generation, this maybe because of its short overhangs, and a coupe-like roofline. Overall, the aesthetic looks of the car are achieved through balanced proportions. Design features emblematic of BMW are to be found at the front with its kidney grille inclined slightly forward, in the stylish and elegant side view of the car, and at the muscular rear end. Inside, us we expected, the car is similar to the 5 GT.
When equipped with the Sport Package, the new BMW 5 Series Sedan includes Adaptive Drive, which encompasses Driving Dynamics Control, Electronic Damper Control, and Active Roll Stabilization. Optional Integral Active Steering will virtually extend or shorten the vehicle’s wheelbase for improved stability at high speeds and enhanced agility at lower speeds.
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.
The upright BMW kidney grille – even appearing from some angles to lean forward – symbolizes the forward-pushing motion of the sedan and, together with the powerfully flared wheel arches, gives the front end of the car strong charismatic presence.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. And last but not least, the direction indicators and brake lights also come in LED technology.
The cockpit is inclined towards the driver at an angle of approximately 7o and the asymmetrically designed center console likewise emphasizes this clear orientation to the driver. 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 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.
With the new 5 Series sedan, BMW’s 4th generation iDrive control screen appears in two versions: with 7.0-in. dimensions and 800 x 480-pixel resolution in standard form, or with the optional Navigation system, in a dazzling 10.2-in., 1280 x 480-pixel version with a wider range of features and functions as in the new BMW 7 Series. Displays are transreflective so that light from the sun actually enhances the images on the screen. 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.
The new 5 Series will be offered in the United States with a choice of three gasoline engines. At its introduction, the new 5 Series will be available as a 535i and 550i. The 528i and xDrive all-wheel drive variants of all three models will arrive later in the year.
The 550i is powered by BMW’s 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 from 1800 to 4500 rpm. 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.
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.
New 8-speed automatic transmission
All new BMW 5 Series models will feature an 8-speed automatic transmission. Compared to the 6-speed automatic offered in past BMW models, the 8-speed’s “taller” cruising gears make a significant contribution to reduced fuel consumption and emissions, as well as quietness. 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.
Brake Energy Regeneration
The new 5 Series sedan continues the roll-out of BMW’s Brake Energy Regeneration system on US models. To save energy and reduce the vehicle’s fuel consumption over time, this system manages the times at which the alternator charges the battery.
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.
EPS Electric Power Steering making its debut in the BMW 5 Series.
The new BMW 5 Series Sedan is the first car in its segment to feature EPS Electric Power Steering. Contrary to conventional mechanical/hydraulic systems, steering assistance is provided in this case by an electric motor activated only when assistance is necessary or desired by the driver. The consumption of energy is reduced to zero when driving in a straight line or when taking a corner with a steady steering angle.
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.
Available as a stand-alone option on the new 5 Series Sedan, Integral Active Steering builds on BMW’s original Active Steering system which debuted on the previous-generation 5 Series.
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.
Electronic limited-slip differential
When DSC is fully de-activated, an electronic limited-slip differential comes into play in vigorous driving. By judicious application of the individual rear-wheel brakes, DSC simulates the effect of a traditional mechanical limited-slip differential. This has the effect of better apportioning power between the two rear wheels and thus improving traction in this driving situation.
Wheels and tires
The 550i and 535i feature standard 18 x 8.0 alloy wheels, fitted with 245/45R-18 run-flat all-season tires. The 528i features 17 x 7.0 alloy wheels with 225/55R-17 run-flat all-season 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.
BMW Parking Assistant
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.
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.
Frontal Collision Warning with brake activation function combined with Active Cruise Control and Stop & Go.
The 5 Series’ standard Cruise Control adds new functions. One is the ability to apply the brakes to maintain the set speed on longer downhill stretches; another is continuously monitoring the vehicle’s lateral acceleration and adjusting the speed if rounding a curve too quickly would upset passenger comfort.
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.
Lane Departure Warning: camera-based system warns the driver of unintended lane departure even in the dark.
Employing a camera near the interior rearview mirror, Lane Departure Warning monitors road lane markings. When switched on, anytime the vehicle begins to move across a lane marking without the turn signals activated, this system vibrates the steering wheel. If the driver does activate the signals, LDW does not react. Lane Departure Warning detects unintended departure from the appropriate lane at a speed of at least 70 km/h or 43 mph. This system is made up of a camera fitted near the interior mirror on the windscreen, a control unit for comparing data, and a signal generator making the steering wheel vibrate as in the case of a Active Blind Spot Detection .
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.
Xenon Adaptive Headlights
Xenon Adaptive Headlights illuminate the road ahead clearly and brightly under all conditions, following curves and winding routes. In the process the headlights turn in the same direction as the steering wheel, following the steering, the yaw rate and the speed of the car.
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.
BMW Night Vision with Pedestrian Detection.
The main feature is a thermal imaging camera fitted at the front end of the car and naturally designed appropriately for the new BMW 5 Series. This camera provides a video image in real time presenting people, animals and other heat-emitting objects in high resolution in the central Control Display, even when they are outside of the headlight beam.
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.
