The BMW Vision EfficientDynamics Concept Car has been revealed

BMW has released full details, including a massive 90 photos and a video, on the BMW Vision EfficientDynamics Concept Car. And it really is quite impressive.

We speculated a couple of days ago that the Vision Concept would be a diesel electric hybrid with stunning performance and impressive economy. And it is.

The Vsion Concept is a plug-in Hybrid with a  1.5 litre, 3-pot turbo diesel with 163bhp and a peak of 224lb/ft of torque. Which in itself is pretty impressive, but when you throw in to the equation a couple of electric motors – one in the transmission as in the ActiveHybrid 7 and another at the front wheels – you end up with 356bhp and 590lb/ft of torque. That translates in to a 0-60 mph of 4.6 seconds.

The sensible thing with the Vision Concept is that performance is designed to come from a blend of the electric motors and engine, instead of using one to power the other. A lithium-polymer battery back weighing in at 87lbs runs down the centre tunnel and can be charged in 2.5 hours from a domestic socket and is enough to power the Vision for 31 miles on electricity alone, althouigh that is not the point.

Aerodynamic efficiency is a big deal on the vision, and BMW are quoting a drag coefficient of just 0.22. This aids economy as does the low weight of the Vision, at just over 3,000lbs (under 1.4 tonnes). The highly efficient 3-pot diesel – which is effectively half of the V6 diesel in the 335d – means huge economy and the Vision makes do with a 5.5 gallon tank which will yield a 400 mile range, averaging over 75mpg.

There is more information in the BMW Vision EfficientDynamics Concept Car Press Release – which is huge –  and a full set of photos in the gallery for the BMW Vision Concept. Plus of course the video below.
