Have more patent drawings leaked of an upcoming model? These are supposedly the patent drawings of the upcoming BMW 6 Series four-door coupe. Last year gave us a preview of its CLS competitor with the unveiling of the Gran Coupe Concept. If these drawings are true, the production version remains pretty close to last year’s concept.
The patent drawings have been revealed thanks to Carscoop show a production version that seems to only have subtle changes to the concept. Note the slightly restyled front and rear bumpers.
The BMW 6 Series four-door coupe is expected to go on sale in early 2012, so we should be seeing the production version soon.
Head over to to see the rest of the drawings.
