This is the AC Schnitzer 2011 BMW 5 Series, which is basically nothing more than the German tuner presenting various custom wheels on the 6th generation F10 model.
The AC Schnitzer 2011 BMW 5 Series can be fitted with 4 different types of rims available in 19 and 20 inch sizes and these are the Type IV Wheels (BiColor or Silver), the Type V Lightweight Wheels (Forged) and the Type VIII Wheels (BiColor).
These custom rims do give the Ac Schnitzer 2011 BMW 5 Series an unique look but the real good news is that the tuner is hard at work on developing a number of modifications for the German saloon which include performance upgrades, exhaust systems, suspension solutions, aerodynamic components and accessories for the interior.
