Alongside several other “Efficient Dynamics” models that were officially unveiled at today’s Frankfurt Auto Show was the X6 ActiveHybrid with no less that 480hp. Using a 400hp twin-turbocharged V8 engine from the X6 and combining it with two electric motors the X6 hybrid achieves a massive 480hp and 575 ft-lbs of torque, enabling it to hit 60 mph in just 5.4 seconds.
As a two-mode hybrid system, the X6 ActiveHybrid will be able to travel on pure electric power up to a speed of 37 mph. Unfortunately it can’t drive on electric power long, just 1.6 miles at speeds up to 37mph, before the gasoline engine kicks in.
Interestingly the X6 ActiveHybrid makes use of a 7-speed automatic transmission that can be shifted by the driver. BMW says the tranny is “based on” a CVT transmission and works in two separate modes. There is one mode for around town where one electric motor operates and when the speed is increase or more power is called for the second electric motor kicks in an engages the gasoline engine. That second electric motor then powers the vehicle’s electric systems (power steering, radio, etc.).
BMW says the X6 ActiveHybrid will provide a 20 percent fuel consumption improvement over a similarly powerful non-hybrid engine. The sporty SUV is rated at an average of 9.9 l/100km - or 23.8 mpg. That isn’t likely to please Green Peace, but it is an impressive number for such an incredibly powerful AWD vehicle.
The X6 ActiveHybrid will go on sale in the U.S. later this year.
