BMW have released another teaser video of the 2012 M5 undergoing high speed testing at the Nardò proving grounds in Italy.
These cars are now a production version of the M5 concept coming close to final form, a electronically dampening suspension and a twin-turbo 4.4-liter V8 with approximately 570 BHP and 720 Nm of torque.
Taking all this power to the rear wheels will be a seven-speed dual-clutch transmission and rumour has it an all-wheel drive could eventually be offered.
The car is expected to be shown at the Frankfurt Motor Show, but the video hints that it may show off production ready vcarinets off at M-Power in June.
