BMW ‘reveals’ new EfficientDynamics prototype

BMW has established a Web site called www.dontblogabouthis.com with the express purpose of revealing a prototype being used to test a new gasoline-electric driveline earmarked for a future sports car. It’s expected to be launched in 2012 as part of BMW’s EfficientDynamics program. Featuring two short videos and four photographs of a 6-series based prototype, the Web site provides no additional information about the prototype other than to suggest that the car in question is “more than a 6-series”and is “not in its final stage.” Close inspection reveals the matte black BMW mule has a new front end resembling that of the one-off EfficientDynamics concept revealed at last year’s Frankfurt motor show.
