G-Power has prepared an upgrade program for the 2012 BMW M6 Coupe. The German tuner is no stranger to creating aftermarket programs for the BMW M6, but this is the first time when they focus on the new model. Known as the M6 Bi-Tronik III, the power kit lifts output to 640 HP (471 kW) and 777 Nm (573 lb-ft), representing an increase of 80 HP (59 kW) and 97 Nm (71 lb-ft). They did this optimizing the twin-turbo V8 4.4-liter engine. As a result, the coupe is now capable of achieving a top speed of 310 km/h (192 mph), even more than the version fitted with the optional M Driver's Package that can reach "only" 189 mph (305 km/h). Other changes include a four-pipe stainless steel exhaust system, carbon fiber brakes, 21-inch Silverstone RS alloys and an adjustable RS coilover suspension.
