BMW M6 Gran Coupe spotted testing

Our trusty Teamspeed spies catch the production ready BMW M6 Gran Coupe testing about in Munich earlier today. The stunning 6-series Gran will be powered by the sophisticated 4.4-litre bi-turbo V8 power-plant from the X5 and X6 M versions and we gather the new M6’s motor will develop roughly 570 to 580 hp. The car is rumored to become true Mercedes CLS AMG-fighter when it will hit show rooms in autumn this year. Stay tuned for more soon!
