One of the sharpest and sleekest M models ever built has hit the interwebs today. The BMW M6 Gran Coupe will on sale in Gemrany in May 2013 and will take on an equally sleek and sporty opponent, the Mercedes-Benz CLS 63 AMG.

Just like the M6 Gran Coupe, the Mercedes CLS 63 AMG uses a V8 twin-supercharged V8 that sends 525 hp to the rear wheels. With the optional AMG Performance Package, the power is raised to 557 hp, close to the 560 horsepower delivered by the M6 Gran Coupe.

Both vehicles are built open the standard models and aim to bring a new level of sportiness and luxury to the respective performance sub-divisions. Since the beauty is in the eye of the beholder, we will refrain to draw a conclusion on which model stands out more since we believe they both have an unique and beautiful design.
