At the 2013 Geneva Auto Show, German tuner AC Schnitzer brings out a 6 Series Gran Coupe project.

The 640d GC model is painted in the Magic Copper color and uses an extensive array of carbon fiber parts, starting with the carbon fiber front splitter and ending with the carbon fiber rear bumper insert. At the front, the tuner offers a lower chrome grille insert, while in the back a new sports exhaust system is fitted to the car for enhanced acoustics.

AC Schnitzer-designed wheels are included in the package.

Interior changes are limited but appear to include a sport steering wheel, body color trim and alloy pedals. We can also see an aluminum iDrive cover and velour floor mats.

Here are some photos live from Geneva:
