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. Many of the concepts are planned for use on upcoming BMW road cars, including an exciting Z10 EfficientDynamics range-topping model due by 2015.

Small Roadsters, in the vein of the old British open-topped 2 seater ( and its modern ‘Homage’ version – the MX-5) will, I’m sure, see something of a renaissance in the next few years as people start to turn away from big, profligate cars, but still seek some fun motoring.
