2012 M5 (F10 M5) front fascia design unveiled. Shot of S63 motor.

Looks like the front end looks like the M3 afterall

With a bit of the X5M thrown in. Money shot = exposed S63 motor!

I cannot wait to see how much more power they tune out of this thing compared to the x6 and x5 M.

Just read around that people are expecting 580-600hp from the S63 engine in the M5 !

Bet the X5/X6M guys will trying to figure out how their same engines can produce that much more power.

What people are expecting and what they will get are two different things. I am sure it'll put out a monstrous amount of power, but the question should really be augmented by how much it'll weigh and how it will handle. After all, we aren't buying an American muscle.
