Just when you thought an electric car couldn't produce for the "need for speed" public... well it can't.  BMW envisions a sustainable answer to private transportation with a diesel counterpart. The Vision EfficientDynamics Concept boosts the silent efficiency of an electric motor with a 3.7 liter diesel engine performing comparable to an M3.  BMW is making the statement that they will be big players in the future of automotive design.  The technology accenting this concept is not one of those that are wasted in vain only to find its place in the history of auto shows.  Though this is a radical concept the upcoming M1 will boast a slightly modified drive train taken directly from it.  This car is built specifically to push the envelope on what is the standard for what cars should embody and BMW aims to be "the leader in sustainability" with EfficientDynamics... Advanced Diesel is coming.
