The Mercedes-AMG GT 4-Door Coupé is an executive car introduced in 2018 by Mercedes-AMG as a five-door variant of the AMG GT two-door sports car.
The AMG GT 4-Door Coupé uses a front-engine layout with 4MATIC+ fully variable all-wheel-drive (rear-biased), and is available with either a 3.0 L M256 turbo/supercharged inline-six engine or a 4.0 L M177 twin-turbocharged V8 engine. The inline-six engine features a conventional turbocharger as well as a mild hybrid system that Mercedes-Benz calls "EQ Boost", which uses an electrically driven supercharger and a 48 volt electric motor that when combined, produce an extra 21 hp (16 kW) and 184 lb⋅ft (249 N⋅m) of torque in addition to the petrol engine when it is not powering the electrical system. This system traces its roots back to the Mercedes CLS53. The car utilises the rear anti-roll bar to increase chassis stiffness, as well as active aero, including an electronically adjustable rear spoiler and electronically operated front louvers in the front grille, that can open and close to manage airflow through the radiator from the AMG GT R flagship sports car.

The GT 63S is the top of the line variant of the GT 4-Door and features the same 4.0L twin-turbocharged V8 engine as in the GT 63, but receives further tuning to produce 470 kW (630 hp; 639 PS) and 900 N⋅m (664 lbf⋅ft) of torque. The GT 63S will reportedly accelerate from 0–100 km/h (0–62 mph) in 3.2 seconds and attain a top speed of 315 km/h (196 mph) as tested by the manufacturer. Auto Bild tested 0–100 km/h (0–62 mph) in 3.0 seconds, 0–160 km/h (0–99 mph) in 6.6 seconds and 0–200 km/h (0–124 mph) in 10.2 seconds.
Additionally, all of the equipment and features from the GT 63, as well as the selectable "Drift Mode", which directs power solely to the rear wheels, comes as standard on the GT 63S as well.
