BMW 4 Series Gran Coupe (2015) revealed in patent pics

The BMW 4 Series Gran 4 Coupe is proof that BMW is continuing its efforts to fill every imaginable niche. It's a four-door version of the 4 Series coupe, which itself is based on the 3 Series saloon, and adds to a bewildering array of machines stemming from the F30 3 Series. Officially the 4 Series Gran Coupe, revealed in full in these images from the firm’s design patent, is given the ‘F36’ codename and is expected to be officially unveiled in early 2014. It joins the F30 (3 Series saloon), F31 (3 Series Touring), F32 (4 Series Coupe), F33 (4 Series Convertible), F34 (3 Series Gran Turismo) and F35 (3 Series long-wheelbase saloon) to complete the range of body styles.

It's based on the same new platform – called MFA for ‘Mercedes Front-wheel drive Architecture' – that has already spawned the new A- and B-Class cars.
