Last January BMW introduced the ActiveE Concept at the Detroit Auto Show, part of its nascent but growing Project i task force for greener vehicles. This year, the talk is centered around the Megacity Vehicle, and today, two interesting bits of information have leaked onto the web.

First, the Megacity Vehicle (MCV) is pegged to get a BMW sub-brand badge that simply adds an 'i' to the usual suspects. That's slick and simple, though we wonder if Apple will have anything to say about it. The image above purports to be the real deal, ready for plastering on trunk lids.

Second, the BMW i MCV could arrive, in concept form at least, as early as the 2011 Detroit Auto Show. All-electric and built largely from carbon fiber, the MCV is a tour de force of high-tech efficiency treatment wrapped in the smallest possible package. BMW has already announced that the vehicle will be intended for sale in 2013, meaning an early concept in Detroit could presage small-batch lease/testing through late 2011/early 2012, just as it's currently doing with the ActiveE.

We haven't heard or seen anything else to substantiate the presence of the BMW i MCV at the 2011 Detroit Auto Show, however, so don't hold your breath. It may be a long wait. The first public showing expected as of now is at the 2012 Olympic Games in London.
