As a member of the AMG GT family, the new AMG GT 4-Door Coupé follows the design philosophy of Sensual Purity. It picks up on the striking proportions, the convex surfaces and the muscular body of the two-door variant and further develops these into the characteristic shape of the four-door version. The flowing silhouette with low greenhouse and dynamic fastback underscores the sporty focus.

The front end is markedly dynamic with its broad, low-drawn "shark nose", filigree MULTIBEAM LED headlamps with carbon-fibre elements, AMG-specific radiator trim and front apron featuring further-developed jet wing (with flowing A wing in the case of six-cylinder models). The heavily contoured powerdomes on the long bonnet allude to the powerful unit housed underneath it, while the broad wings make the dynamic potential of the AMG GT 4-Door Coupé distinctly visible. As with the two-door AMG GT models, a radiator blind, the so-called AIRPANEL, positioned in front of the central radiator air inlet improves the vehicle's aerodynamic efficiency according to requirements. The striking front splitter reduces lift on the front axle.

Characteristic Coupé architectural features include the frameless side windows and the flat windscreen which is drawn widely towards the rear. Even from the side perspective, the "shark nose" design looks especially dynamic and feisty. The tapered side line and the broad shoulders hint at the athletic and sporty orientation of the vehicle. Depending on the engine version, the heavily pronounced wheel housings are home to a broad range of 19 and 20-inch light-alloy wheels, not to mention optional 21-inch forged wheels, all of which provide a high degree of personalisation.
