Mysterious BMW 6-Series teased in anti-blog site

How do you get blogs to write about something?  Tell them they can't.  In a clever marketing move, BMW has launched DontBlogAboutThis.com, which features a mysterious 6-Series prototype.

While were not exactly sure what it is, speculation falls into three camps: EV, hybrid, or plug-in hybrid. The tailpipe suggests there is a petrol or diesel engine, so it's probably not an EV. Likewise, BMW has multiple hybrids so it seems kind of odd to make a big fuss about a hybrid version of an outgoing model. This seems to imply the prototype is a plug-in hybrid.

If you look at the front end, the bumper seems to resemble the Vision EfficientDynamics Concept. While this could be a coincidence (or a trick), it would seem logical that BMW would have started testing VED prototypes if reports of a 2013 introduction are correct.

As we have previously reported, the Vision EfficientDynamics Concept is a plug-in hybrid with a three-cylinder turbodiesel engine and two electric motors. Boasting 262 kW (356 PS / 351 hp) and 800 Nm (590 lb-ft) of torque, the 2+2 coupe accelerates from 0-62 mph in 4.8 seconds before topping out at an electronically limited 155 mph. Despite the impressive performance, the concept only consumes 3.76 liters/100km (equal to 62.6 mpg) while emitting 99 grams of CO2 per kilometer.
