BMW has two new hybrids coming to the upcoming 2009 Frankfurt Motor Show. One of the two, the BMW X6 Hybrid, promises to be the most powerful hybrid vehicle ever offered with 478 hp and 575 lb-ft of torque from its twin electric motors and 4.4L V8 engine combination.

According to what appear to be leaked specs from BMW, the X6 Hybrid will do 0-60 mph in about 5.5 seconds while returning a 20% fuel mileage improvement over the standard X6 with its twin-turbo V8. To set the hybrid apart from its standard sibling, BMW will bestow the new fuel-saver with a power dome hood and metallic blue paint.
