The BMW X6 ActiveHybrid has arrived, and as previously covered, the new gas-electric X6 will be the most powerful hybrid in history, with 480 peak horsepower and diesel-like plateau of 575 lb-ft of torque.
That impressive powertrain consists of twin electric motors (delivering 91 hp and 86 hp, respectively) and a twin-turbo 4.4-liter V8 engine. All those horses will be corralled through a seven-speed dual-mode transmission and BMW’s xDrive all-wheel-drive system. The run to sixty will take just 5.4 seconds and the top speed will be limited to 130 miles per hour.
The EPA has yet to test the vehicle, but the German automaker is estimating its X6 Hybrid will return a 20-percent fuel mileage improvement average over the standard twin-turbo X6. That should mean about 18 miles per gallon combined in the States. The official public debut is scheduled for the Frankfurt Motor Show in September and the sale date is slated for four-quarter 2009.
