Claus Ettensberger Corporation unveiled the ACS6 by AC Schnitzer based on the 2012 BMW 650i Coupe at SEMA 2011. This beautiful work-of-art illustrated the attention to detail that only a tuner like AC Schnitzer can appoint. The subtle craftsmanship was appreciated and very well received by show goers. The ACS6 sat on 21” ACS Type VIII Forged wheels with 21″ Michelin Pilot Super Sport tires also donning front and rear ACS spoilers. The car also featured the ACS exhaust system and the chrome front grill treatment.
