2012 BMW M6 Spied Testing, gets New M5�s Twin-Turbo V8

These are some of the clearest spy shots of BMW�s next M-branded model, the M6 Coupe, which will take its place as the flagship version of the new F13 6-Series.
The recent unveiling of the new M5 sports saloon gives us an idea of what to expect in terms of performance as the M6 will be powered by the same twin-turbocharged 4.4-liter V8 engine.
The force-fed V8 brings an end to a line of naturally aspirated engines for the M6 that started with the iconic straight six of the first generation and continued with the V10 of the outgoing model.
