A production sports car based on last year's BMW Vision EfficientDynamics concept will reportedly debut at the 2011 Frankfurt Motor Show and come to market by 2013. According to Germany's AutoBild, the car which they refer to as the I100 (as part of BMW's project I which is also spawning the MegaCity EV) will be powered by a hybrid powertrain much like the one in the concept.
A 1.5-liter three-cylinder engine (possibly a diesel) paired with an electric motor based on the architecture of BMW's mild hybrid 7 Series would drive the rear wheels, while a second motor would drive the front wheels. A lithium ion battery pack is earmarked to provide electrical energy storage, although it's not clear if the plug-in capability of the concept would be retained.
According to Autobild, it's also possible that we'll see an M variant of this car using the 450 horsepower twin-turbo inline-six from the next generation M3 along with set of supercapacitors instead of a lithium battery pack.
