The 6-series has been BMW's big sport coupe, sitting in the lineup between the 5-series and 7-series. Next year, BMW will sell what it calls a Gran Coupe version of the 6-series, with two rear doors allowing easier access to the rear seat.
The first model available will be the 640i Gran Coupe, with BMW's excellent direct injection, twin scroll turbocharged 3-liter inline six-cylinder engine, tweaked for more horsepower than the current incarnation. Later, BMW will introduce the 650i Gran Coupe, which will get a twin turbocharged direct-injection V-8.
The head unit electronics represent the latest technology in BMW's arsenal, including its connected features. Navigation will likely be standard on the 6-series Gran Coupe, as deleting the LCD would leave an odd hole in the dashboard design.
