BMW is proud in announcing the latest addition to its 7 Series, the ActiveHybrid 7, at the 2009 Frankfurt Motor Show. The German luxury carmaker touts the ActiveHybrid 7 as a car that will set new standards for performance and efficiency in the premium luxury class.
BMW touts the ActiveHybrid 7 as its only model using electric turbo, thanks to an electric motor continuously backing up its main conventional engine. This, plus a 3-phase electric synchronous motor, allows the BMW ActiveHybrid 7 Series to accelerate much faster than the BMW 750i.
The BMW ActiveHybrid 7 Series could be driven from zero to 100 km/h in only 4.8 seconds, and reach an electronically limited top speed of 240 km/h (150 mph) speed. The ActiveHybrid 7 is around 15-percent more fuel efficient than the 750i.
The motor works together with a TwinPower V8 turbo engine that renders 455 hp of output and 516 lb.-ft top torque. The electric motor is well-positioned between the torque converter and the engine, which is mated to an automatic 8-speed transmission.
The ActiveHybrid 7 is also the first BMW model that has an automatic transmission that uses an Auto Start Stop system.
According to Klaus Draeger, a BMW board member, the enhanced performance and improve fuel efficiency and carbon dioxide emissions form the idea behind the carmaker’s Efficient Dynamics strategy, which aims to combine greater dynamics and greater efficiency.
When BMW launched the new 7-Series in 2009, the luxury car established the standards for comfort and driving dynamics. Now, the ActiveHybrid 7 sits on double-wishbone front suspension and an improved Integral-V rear suspension to deliver ride comfort expected of a BMW sport-luxury sedan as well as offer the handling and control typical of a sports car. The long-wheelbase version of BMW 7 ActiveHybrid features self-leveling rear suspension.
Both the standard- and long-wheelbase BMW ActiveHybrid 7 are equipped with BMW's vehicle speed-variable Servotronic power steering and Driving Dynamics Control. Interestingly, the driver could select the desired shock absorber setting, shift character of the automatic transmission, throttle response, appropriate operation of Dynamic Stability Control as well as Servotronic steering assist.
Meanwhile, BMW 7 ActiveHybrid is fitted with a brake system on the BMW 7 ActiveHybrid that makes use of fade-resistant inner-vented discs and floating calipers (front and rear). As standard, the 7 ActiveHybrid rides on 19-inch light-alloy wheels in an aerodynamically optimized 10-spoke Aero turbine design.
These rims are shod with run-flat tires -- measuring 245/45 R19 on the front and 275/40 R19 on rear – that allow the new 7 ActiveHybrid to continue on its course at a max speed of 50 mph for up to 150 miles even after completely losing pressure. Likewise, Tire Pressure Monitor will provide a warning if the air pressure in any of the rubbers drops more than 20 percent.
