BMW tuning specialist Manhart Racing has upped the Gran Coupe’s power by 100 or so horse and given it a set of M5 alloys.
German tuning house Manhart Racing recently revealed its latest 6 Series aftermarket project, this time focusing on the 650xi Gran Coupe. Power enhancements consist of a software upgrade that increases output of the Gran Coupe's 4.4-liter turbo V8 from 450 horsepower and 479 pound-feet of torque to 543 hp and 538 lb-ft. The boost is further facilitated by Manhart's own stainless-steel downpipes and sport silencers rear and center, as well as the brakes from an M5 with its own custom adaptations.
Visual tweaks have been limited to new front and rear spoilers, side skirts, a diffuser and a set of 20-inch M5 forged alloys, with 19-inch wheels available for the winter.
