BMW announced the production version of the BMW ActiveHybrid X6. The BMW ActiveHybrid X6 will make its world premiere at the Frankfurt Motor Show (IAA) in September and will reach US BMW Centers in fourth-quarter 2009. The overall drive system featured in the BMW ActiveHybrid X6 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 ActiveHybrid X6 at all speeds, with acceleration from a standstill to 60 mph in 5.4 seconds. Top speed of the BMW ActiveHybrid X6 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 ActiveHybrid X6 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. 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.
