German powerhouse tuner AC Schnitzer has spent some time fettling the new BMW 6 Series Gran Coupé, the result being a 360-horsepower 640i sedan with all the restraint of a Mako shark. The additional grunt adds up to 40 hp for the 640i and 47 hp for the 640d, with said grunt made more finely tuned as it rides on Schnitzer's own spring kit and wheels that range from 19 to 21 inches in diameter.
Touring car racing fans are eagerly anticipating the return of BMW to the DTM series. The Bavarian automaker last competed in DTM (or its progenitors, anyway) a whopping 18 years ago, but late last year announced it would return to the German touring car series in 2012. Now it has revealed the means to that end.
