Specifications

The AMG GT 4-Door Coupé uses a front-engine layout with rear-wheel-drive or 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.[6][7] 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.[8] This system traces its roots back to the Mercedes CLS53.[9][10] 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.[11][12]

Variants

Mercedes-AMG GT 43

The GT 43 is the entry level variant of the AMG GT 4-Door Coupé and features the M256 3.0L Twincharged inline-six and the 4MATIC+ AWD system. The engine produces 270 kW (362 hp; 367 PS) and 500 N⋅m (369 lbf⋅ft) of torque and can accelerate from 0–100 km/h (0–62 mph) in 4.9 seconds, with a claimed top speed of 270 km/h (168 mph).[13][14]

Mercedes-AMG GT 53 4MATIC+

The GT 53 is the more powerful version of the GT 43. It features the same 3.0L turbo/supercharged inline-six, but with higher outputs. The engine produces 320 kW (429 hp; 435 PS) and 520 N⋅m (384 lbf⋅ft) of torque. The starter-generator and electrically driven supercharger called EQ boost supplements the engine temporarily with 16 kW (21 hp) and 250 N⋅m (184 lbf⋅ft) of torque while under full acceleration.[15] It can accelerate from 0–100 km/h (0–62 mph) in 4.5 seconds, along with attaining a top speed of 285 km/h (177 mph) as tested by the manufacturer.[16][17] The suspension uses steel springs and adaptive dampers and the gearbox is a 9-speed unit that uses a conventional torque converter.[18] The GT53 can be optioned with the more aggressive "Aero Package". this package includes a more pronounced front splitter, with lager air vents to allow for more efficient cooling, combined with a deeper and larger rear diffusor and both fixed or movable (electronically) rear wing.

Mercedes-AMG GT 63 4MATIC+
Mercedes-AMG GT 63

The GT 63 is a high performance, better equipped variant of the GT 4-Door and features the AMG M177 4.0L twin-turbocharged V8 engine, which produces 430 kW (577 hp; 585 PS) and 800 N⋅m (590 lbf⋅ft). It has a claimed 0–62 mph (100 km/h) acceleration time of 3.4 seconds and a top speed of 311 km/h (193 mph) as tested by the manufacturer. The GT 63 also has an optional selectable "Drift Mode" which directs power solely to the rear wheels.[20] The car comes standard with an electronically controlled limited-slip rear differential and rear-wheel steering, and features an MCT gearbox with a wet clutch to handle the extra power. The GT 63 uses AMG's multi-chamber air suspension for a sportier, more adaptive ride and has cylinder deactivation mode for increased efficiency.[18]

Mercedes-AMG GT 63 S 4MATIC+
Mercedes-AMG GT 63S

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.[21] 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.[22]

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.[12]
