BMW has revealed a radical vision for its future performance-oriented models in a spectacularly styled concept car whose combination of M3-rivaling acceleration and Mini Cooper-beating fuel economy will likely make it one of the stars of this year's Frankfurt motor show.
At the heart of the concept car is an advanced diesel-electric hybrid system, based on a compact turbocharged 1.5-liter, three-cylinder common-rail diesel engine that will first appear in the second-generation 1-series due in 2011.The front-mounted engine features a gutsy 163 hp and 214 lb-ft of torque, making it more powerful than the latest and most-economical version of BMW's existing turbocharged 2.0-liter four-cylinder. It channels drive to the rear wheels via a version of the Getrag-developed six-speed dual-clutch gearbox introduced on the M3.
The diesel engine is supported by a pair of electric motors mounted at the front of the gearbox, one supplying drive to the rear wheels, the other to the front wheels via a single-speed transmission.
