Second model revealed today at the 2011 Frankfurt Auto Show by the German tuner specialists at AC Schnitzer is a 6 Series Convertible with a power and cosmetic package.

AC Schnitzer’s 6 Series Convertible show car is based on the 650i model which receives a significant power upgrade. From the standard 407 hp, AC Schnitzer gives the 650i mode a whooping 540 hp by using a new exhaust system and a re-mapped ECU.

The AC Schnitzer 2012 BMW 6 Series Convertible comes with a new body kit, featuring a redesigned front spoiler and a rear skirt protected by a special foil.

To cope with the increase power and provide adequate braking distances, AC Schnitzer also upgrades the brakes of the 650i Convertible which now has 8-piston high performance calipers on the front axle. The car also sits on 21 inch wheels (19-inch and 20-inch available too) and new springs.

Inside, AC Schnitzer includes a new steering wheel with airbag, an aluminum cover for the iDrive controller, aluminum pedals, and new floor mats.
