Following a couple of previews, BMW specialist AC Schnitzer finally reveals details of its thorough tuning program for the M6 family. It covers the M6 Coupé, the M6 Convertible and also the M6 Gran Coupé as they all share the same features. It’s up to you to decide which one you like more.

Beginning with the 4.4 liter bi-turbo V8 engine, AC’s engineers adjust a few things and cranks the power up from the standard 560 hp to 620 hp with 790 Nm of torque. That results in a top speed of 305 km/h.

Next stage is chassis tuning. AC provides a sport suspension spring kit that lowers the M6 by 15mm on the front axle, and a full 25mm on the rear. That increases the car’s cornering abilities and also make it look cooler.

Then we move on to the aerodynamic body kit, consisting of carbon front spoiler, chromed front grille, carbon rear diffuser and rear spoiler (Coupé only), rear skirt, and sport silencer. The design is typical AC Schnitzer; subtle, sporty, elegant. As for the wheels, you can choose between 20 and 21-inch Type VIII (one-piece/multipiece/forged), Type V (forged) and Type IV wheels.

Inside the cabin, the M6 is fitted with “Black Line“ aluminium cover for BMW “i-Drive system controller“ (anodized black/matt), aluminium pedal set for left- and right-hand drive (anodized/matt), aluminium footrests (anodized/matt) and floor mats in velours.

So, which one’s your favorite? We’ve always had a soft spot for the Gran Coupe!
