The facelifted BMW 6-Series Coupe was released almost a year ago, revealing a more dynamic coupe and convertible with for the first time a diesel engine. AC Schnitzer, the Aachen, Germany based tuning house, has set out to further refine the 6-Series facelift model.

Head designer Michele Viandante has worked on a new front fascia with a sharpened kidney grille, new rear-spoiler with built-in third brake light and side skirts which make the car look more flat than before. A sports rear silence with chromed tailpipe finishes the look in the back.

And even if the car itself may look more flat than before, performance is far from flat. AC Schnitzer has performance packages for both the 650i and the new 635d. AC Schintzer can increase displacement for the 4.8 liter eight-cylinder engine to 5.1 liters resulting in a power increase of 44 hp, to 411 hp. Top speed is increased by 35 km/h from its limited 250 km/h.

Of course the diesel engine is not forgotten, and AC Schnitzer sqeeuzes out and additional 24 hp to reach 310 hp from the 3.0 liter twin-turbo diesel engine, torque increases by 100 Nm to 680 Nm. The ACS6 is available with 20 inch Type VI alloy wheels.
