BMW 6 Series Gran Coupe

BMW has previously confirmed that it plans to build a production version of the 6 Series Gran Coupe Concept that it unveiled at the 2010 Beijing Motor Show, and these plausible-looking patent filings appear to give a glimpse at the car's final design. Much like BMW's latest batch of concept cars – the M5 and 6 Series Coupe, notably – the "finished" product doesn't stray too much from the original concept car, save, of course, the traditional dumbing-down of air intakes and wheel sizes.

The 6 Series Gran Coupe is expected to slot in between the BMW 5 Series and 7 Series in terms of both size and price, and will likely use the same range of turbocharged six- and eight-cylinder engines that we see in those models. While not as overly swoopy as its competitors, the 6 Series Gran Coupe will be poised to do battle with the Audi A7 and Mercedes-Benz CLS for four-door coupe luxury supremacy.
