It’s still not set in stone, but a release date of 2012 and a price in the region of $200,000 are the latest details on BMW’s Vision EfficientDynamics eco-supercar. Apart from having to do something about the clunky name, the Munich motormeisters will be offering 328 hp and 62.6 mpg from a hybrid drivetrain that includes a three-cylinder diesel engine. If the future means stuff like thisthe Porsche 918 Spyder hybrid, Audi E-tron EV and Mercedes-Benz SLS E-Cell then being environmentally friendly actually sounds like fun. If these cars even make a sound.
