Introducing for the first time - the production BMW 6-series gran coupe spied during testing! The beautiful 6-series gran coupe is a sedan-coupe take on the F13 6-series coupe and features frameless windows. As earlier patent images revealed, the Gran Coupe shows the same front and rear bumpers as the existing 6-series models F12 and F13.

The 6-series Gran Coupe is quite a bit longer than the 6-series coupe and convertible. The Concept Gran Coupe unveiled back in 2010 has a length of over 5m (197 inches) while the 6-series coupe is 4.9m or 192.7 inches. These spy shots suggest a similar increase in size.

The wheels have also been sized down for practical purposes.

Expect the 6 Series Gran Coupe to feature the same range of engines as the current 6-series coupe and convertible.

Based on previously info, we’ve tentatively pegged its debut to be sometime mid-next year.
