In 2003 the second version of the 6 Series saw the light of day at the Frankfurt Motor Show. Gone were the backward rake of the nose and the squared off lines. In their place was a gracefully rounded shape with nary a squared-off corner to be found. Once again, the coupe's platform was based on the 5 Series, and, once again, it was greeted with enthusiasm by fans of the marque. The enthusiastic reception was understandable since the 645Ci premiered with a potent 325 horsepower 4.5 litre V8. A more modest 630Ci, with a 258 horsepower six, followed shortly thereafter. Another M6, with a strapping 507-pony powerplant, came along in 2005
