China’s notoriously leaky patent office has done it again. These are the official patent drawings for the new BMW 4 Series Gran Coupe that will debut on the Geneva Motor Show in March. The 4 Series Gran Coupe is the four-door variant of the 4 Series Coupe. It will compete head-to-head with the Audi A5 Sportback.

The 4 Series Gran Coupe will be about five centimeter longer than the Coupe, which means, in combination with the sloping roof line, that there won’t be much space for the heads in the back. The 4 Series Gran Coupe will be launched on the China car market in late 2014, it will be available as 420i, 428i and 435i.
