The
2014 BMW M6 Gran Coupe boasts plenty of power out of the box, but adequate power has never stopped the aftermarket from shooting for more.
AC Schnitzer has now tuned the M6 Gran Coupe to an impressive
665 HP / 652 LB-FT, up from the factory quoted
560 HP / 500 LB-FT.
No exact details yet on the hardware upgrades used to achieve these power levels and the software has yet to be finalized, but that should be forthcoming, eventually. For now, we get a preview through this video.
