After teasing us with some interesting dyno runs with the M6 Gran Coupe, the guys from AC Schnitzer finally revealed their take on the powerful 4-door Coupe.
Even though initially they showed a lot more power could be gained from the S63 engine, the end result of their tests showed that the optimal numbers for the ACS6 Gran Coupe are 620 HP and 790 Nm (582 lb-ft) of torque.
With the extra power, the Gran Coupe is capable of even more mind-boggling performances. The car reaches 300 km/h (187.5 mph) in just 26 seconds, not to mention the 100 km/h (62 mph) benchmark that is reached almost immediately.
The new top speed on now 305 km/h (190 mph) even though the video below shows even greater speeds and the whole thing comes with a 2 year warranty in the limit of 60,000 km (37,500 miles).
Other improvements include the aerodynamic package (made out of carbon fibre and consisting of a front spoiler, chromed front grille and a rear diffuser), the 'acoustically enhanced' exhaust system and some new wheels.
