In 2005, with the BMW M6 E63 and E64, BMW M once again took up the thread of the especially sporty coupé originally spun by the M635CSi: the driving performance of the 286 hp-strong ancestor turned heads in the sportscar world. With two doors, a low window line and a stretched look, the sportiest interpretation of the BMW 6 series pursued the concept of a coupé designed for top performance. BMW M thus closed the gap in this segment left by the BMW 8 Series E31 after 1999. The plan to equip the elegant 2+2-seater with the incomparable V10 engine from the BMW M5 E60, presented in Geneva one year before, proved to be invigorating. It was the ticket to the world of super sports coupés.
