BMW is expanding the 4 Series lineup with a 4-door Gran Coupé. There’ll be five variants at launch: 420i Gran Coupé, 430i Gran Coupé, M440i xDrive Gran Coupé, 420d Gran Coupé and 420d xDrive Gran Coupé. A performance version from the M division is expected to join the lineup in November 2021.
The new 4 Series Gran Coupé has grown in dimensions compared to its predecessor. It measures 4,783 mm long (+143 mm), 1,852 mm wide (+27 mm) and 1,442 mm tall (+53 mm). The wheelbase has grown by 46 mm to 2,856 mm. The front and rear tracks are wider by 50 mm and 29 mm, respectively. BMW claims a perfectly balanced 50:50 weight distribution.
A shear panel increases the front-end torsional stiffness, while the stiffness in the rear axle area is taken care of by underfloor bracing elements. Lift-related dampers are fitted as standard on the new 4 Series Gran Coupé.
