Although we can't quite make out the lower front bumper bar, we could hazard a guess that it will showcase the new 'M' design language, sporting aggressive front ducting on the lower corners and a deep and low scoop and chin spoiler in the middle, like the recently unveiled M5 and 1 Series M Coupe.
Headline features, of course, include the 4.4-litre twin-turbo V8, also seen in the new M5. Power outputs haven't been officially confirmed but it is highly likely the engine will produce the same 412kW of power and 680Nm of torque as the new M5. Performance figures are also likely to be very similar, sprinting from 0-100km/h in around 4.4 seconds.
It will be interesting to see if BMW and M Division offer the M6 with a reasonable weight saving over the M5. The previous generation V10 M5 and M6 were separated by around 45kg - 1755kg for the M5 and 1710kg for the M6 coupe. If there are greater savings on this new model it might be even quicker than the new M5.
The question is, what would you choose if you had to pick between the two? The upcoming M5 or this M6? The new shape BMW 6 Series seems to be quite an improvement on the old coupe, it will make the decision much harder for those in the market for a high-performance grand tourer when this M6 hits the showrooms, sometime in 2013.
The 2012 BMW M6 is expected to be unveiled next year.
