BMW X6 Hybrid

Riddle me this: What's one hybrid the world does not need right now? A performance SUV. Yet BMW is showing a hybrid concept in L.A. this year that's just that.The concept version of the recently redesigned X6 SUV sports a 400-horsepower, turbocharged V-8 engine teamed to a mild hybrid system. The result? Fifteen percent better fuel economy. Compared to a turbo X6, which gets 12/18 mpg city/highway, a 15 percent improvement would be roughly 14/21 mpg. Not exactly in the running for green car of the year, is it?The hybrid system does use advanced lithium-ion batteries and an engine-stop function that kills the gas engine at stops to conserve fuel.
