BMW M5 Prototype testing at the Nurburgring

The 2011 F10 BMW M5 is set to become one of the most sought after cars of 2011. The intensive track testing is a tribute to BMWs commitment to making the M5 the best in class albeit missing the opportunity to turbo charge the now discontinued E60 V10.

The M5 is set to make its public unvailing at the 2011 Frankfurt motorshow after a Teaser at the Geneva Show earlier in 2011.

The 4.4 v8 twin turbo as used in the current x6m will be tuned to around the 550bhp but these figures havent been finalised yet.

Anyway enjoy the Video and the recent prototype images
