We've known about the ins and outs of the lovely BMW M6 Gran Coupe for a while now, but that doesn't mean we weren't happy to see the thing in the metal for the first time, here in Detroit.

The M-tuned Gran Coupe utilizes the same 4.4-liter forced-induction V8 that powers both the BMW M6 and the M5, with an output of 560 horsepower and 500 pound-feet of torque. The fast four-door brings up 60 miles per hour in just 4.1-seconds – the same sprint time as the M6 coupe and a few tenths quicker than the M5 – and up to a limited top speed of 155 mph.

We love those performance figures – this is one new Bimmer that we're amped to get some seat time in – though we're not super crazy about the selection of chrome wheels on this particular show car. Tells us what you think about the hotted up Gran Coupe in comments, below.
