Spy Photos: The new BMW M5 F10

The new BMW M5 F10 came in one of the last phases of testing, being prepared to debut at Geneva Motor Show in 2011. The model will be equipped with a V8 bi-turbo 4.4-liter engine that will develop over 550 hp.

Engineers are testing the new BMW M5 F10 with a very thin layer of camouflage. This time, the new M5 is covered only at the front bumper level, at the profile and the optical blocks. The bonnet of the M5 F10 is also covered, but the camouflage easily reveal us its shape. The model is expected to begin at the 2011 Geneva Motor Show.

The main change of the M5 is sitting under the hood, BMW engineers abandoning the traditional aspired engines in favor of a V8 bi-turbo, present also on the new X5 M and X6 M. The 4.4-liter unit develops over 550 hp and is coupled to a double clutch transmission. Torque provided by the modified engine version is estimated at 800 Nm.
