M6 Gran Coupe Tuned by AC Schnitzer– 665 HP!

The 2014 BMW M6 Gran Coupe certainly makes sufficient power, but having enough or even a lot of power has never discouraged tuners from looking for more. And to that end, AC Schnitzer has now bumped the M6 Gran Coupe’s output to an impressive 665 horsepower and 652 lb.ft of torque. This represents an increase of 105 hp and 152 (!) lb.ft over the factory’s output.

While exact details on how AC Schnitzer accomplished this are unavailable still (we suspect VTEC), we do have this video with dyno test and road run… As soon as we get details, we’ll pass them along. Enjoy!
