BMW's Vision EfficientDynamics concept bound for Frankfurt

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. Called Vision EfficientDynamics, the one-off coupe is a mobile showcase for lightweight construction and plug-in hybrid drive technology, while featuring a variety of futuristic styling, packaging, aerodynamic, lighting and interior ideas under development at the German carmaker's heavily cloaked FIZ development center in Munich.
