Prior Design is giving us a visual example on how to transform a sleek sports saloon like the BMW 6-Series Gran Coupe into a muscled-up brute.

The display model pictured here is an M6, but the same wide bodykit can be used on the regular 6-Series Gran Coupes. It contains front and rear bumpers, rear diffuser, fender attachments, side skirts, trunk spoiler and a new, scooped bonnet.

Also available are a lowered sports suspension from H&R and 20-inch wheels in an assortment of colors, while Prior Design can customize the interior upon request.

The only performance upgrade mentioned by the German tuner is a sports exhaust system with ceramic-coated aluminum endpipes.
