German outfit G-Power is in a league of its own when it comes to tuning BMWs, laying claim to no less than five world records including the fastest sedan, 4-seater coupe and SUV on the planet. Its latest upgrade program is based on the BMW M6, which it previewed last year, and as you may imagine it entails plenty of power and speed. The tuner's Bi-Tronik III power kit increases the 4.4-liter twin-turbo V8 to 640 horsepower and 573 pound-feet of torque, up from 560 hp and 501 lb-ft.

The result is that the M6 can now go from standtill to 62 mph in just 3.8 seconds (an improvement of 0.4 secs over the stock car) en route to a top speed of 196 mph, a jump of 7 mph over the M Driver's Package equipped M6. Engine upgrades aside, G-Power added a set of 21-inch Silverstone RS alloys, a coilover suspension, in-house ceramic brakes, and a custom titanium exhaust system that trims 12 kg off the stock system and comes with 100 mm carbon tailpipes.
