Description: The BMW X6 ActiveHybrid makes its world premiere at the 2009 Frankfurt Motor Show (IAA) and will reach US BMW Centers in fourth-quarter 2009. ActiveHybrid technology provides a glimpse into the future, achieving outstanding driving dynamics with equally impressive efficiency. It melds both of these qualities to offer a truly unique driving experience. The world's first Sports Activity Coupe with full hybrid drive capitalizes on the options offered by combining the combustion engine with electric motors to create a powertrain with new levels dynamic performance and efficiency. BMW ActiveHybrid technology offers a significant increase in driving dynamics and at the same time reduces fuel consumption by approximately 20 percent versus a comparable vehicle powered by a combustion engine alone. The result is even greater driving pleasure combined with enhanced fuel economy and CO2 management providing the kind of progress to make the BMW X6 ActiveHybrid a genuine BMW in the hybrid market. The overall drive system featured in the BMW X6 ActiveHybrid consists of a 400 hp twin-turbocharged V8 gasoline engine and two electric synchronous motors delivering 91 hp and 86 hp, respectively. Maximum system output is 480 hp, and peak torque reaches 575 lb-ft. Precisely controlled interaction of the three power units optimizes the overall efficiency of the BMW X6 ActiveHybrid at all speeds, with acceleration from a standstill to 60 mph in 5.4 seconds. Top speed of the BMW X6 ActiveHybrid is limited electronically to 130 mph, with average fuel consumption in the EU test cycle improved by roughly 20%, and a CO2 emission rating of 231 grams per kilometer. EPA ratings will be available closer to the market introduction. BMW's first full hybrid model is able to run exclusively on electric power - and that is entirely free of CO2 - up to a speed of 37 mph (60 km/h), with the combustion engine being activated automatically whenever required. These performance figures are made possible by utilizing a two-mode active transmission. The ideal combination of the two power modes can be controlled for enhanced efficiency and dynamic performance in any driving condition. With the two electric motors, three planetary gearsets and four multi-plate clutches, drive power is transmitted through a 7-speed automatic transmission. As would be expected in a BMW, the driver can operate the transmission manually. BMW's lauded xDrive all-wheel-drive system distributes the power between the front and rear axles. The electric motors receive their energy from an NiMH high-performance battery pack positioned beneath the floor of the luggage compartment. This battery pack also feeds electric power to the vehicle's on-board network. Luggage compartment capacity is therefore the same as on the original BMW X6. On brake application and/or on deceleration, kinetic energy is converted into electrical energy and is stored in the battery pack. To provide this function either one or both of the electric motors act as a generator, feeding electric power generated back into the high-voltage battery.
