You probably have already seen spy photos of the upcoming BMW M5 (F10) which will be sporting a confirmed 4.4-liter twin turbo V8, same as found in the X5M/X6M. The latest spy photo that we obtained from our sources happens to be the upcoming BMW M6 (F12-body) which puts to rest the notion that BMW was not going to build a revamped 6-Series.

The upcoming BMW M6 was caught testing outside of the Nurburgring sporting LED turn signals, huge cross-drilled rotors, beefy wheels and tires and a slightly reworked body from what we visualize underneath the camouflage.

It is safe to assume that the 2012 BMW M6 will be featuring the same 4.4-liter twin turbo from the upcoming M5 that puts out more than 555hp. The 2012 BMW M6 could be on display revealed at the upcoming Paris Motor Show in October of this year.
