Mercedes-AMG GT 4-Door ’53’, ’63’ and ’63 S’ Models Unveiled
The new Mercedes-AMG GT 4-Door model delivers driving experiences in new dimensions and extends the AMG model family. The new coupé is the first four-door sports car from Affalterbach and draws directly on the legendary SLS and AMG GT models. As another vehicle developed autonomously by Mercedes-AMG it combines unique design, high comfort and outstanding sports car engineering with an athletic, four-door fastback layout. It thus offers more space and more potential uses. Systematic expansion of the AMG GT family with the 4-door Coupé opens up the sports car segment to those looking for a vehicle for day-to-day use, but unwilling to go without the unparalleled performance of Mercedes-AMG.

Longitudinal and lateral dynamics at the highest level, and a striking silhouette with classic proportions put the Mercedes-AMG GT 4-Door Coupé in the portfolio of its two-door brother at first glance. The expressive design with the low bonnet, dominant front and muscular body language emphasises the sporty genes of the four-door coupé, which sets new standards as the youngest model in the AMG family: As the first four-door AMG GT model it combines high everyday comfort with diverse individualisation options and the latest sports car engineering.
GT63 and GT63 S
The exciting AMG 4.0-litre V8 biturbo engine is already used in numerous AMG models. Its output has been enhanced yet further for the new Mercedes-AMG GT63 S 4MATIC+ and ensures superior performance on a par with a sports car. It delivers 639 hp and a maximum torque of 900 Nm, which is available over a wide engine speed range from 2500 to 4500 rpm. The top engine of the new four-door AMG GT thus exudes effortless superiority in every engine speed range. Acceleration from 0 to 100 km/h in 3.2 seconds clearly illustrates this, as does the maximum speed of 315 km/h.
In the Mercedes-AMG GT63 4MATIC+ the V8 unit provides 585 hp and 800 Nm maximum torque. The sprint from standstill to 100 km/h lasts just 3.4 seconds, and the top speed is 310 km/h.
The AMG 4.0-litre V8 engine works with the proven biturbocharging, where the two exhaust-gas turbochargers are arranged not on the exterior, but between the cylinder banks. The advantages of the “hot inner V” are in the compact engine design and the immediate response of the exhaust-gas turbochargers.
In the AMG GT63 S variant the eight-cylinder has active engine mounts. They solve the conflicting goals of achieving as soft a connection as possible to the powertrain for high comfort and as rigid a connection as possible for optimum driving dynamics, by steplessly and quickly adapting their rigidity to the respective driving conditions. As an option the AMG GT63 can be equipped with active engine mounts as part of the Dynamic Plus package.
The AMG SPEEDSHIFT MCT 9G 9-speed transmission is specially tuned to the requirements of the eight-cylinder variants of the new four-door AMG GT. A wet clutch is used here. This reduces weight and inertia and optimises the response. The extensively tailored software enables extremely short shift times and fast multiple downshifts and delivers an especially emotive gearshifting experience thanks to the double-clutching function. There is also a RACE START function, ensuring optimum acceleration.
GT53
Alongside the two V8 engines the new four-door sports car is also available as the Mercedes-AMG GT53 4MATIC+ with the innovative AMG six-cylinder inline engine. The 435 hp 3.0-litre unit is characterised by high performance, supported by a boost effect with an output of up to 22 hp and 250 newton metres of torque.
The EQ Boost starter-alternator combines a starter motor and alternator in a powerful electric motor and is between the engine and transmission. This intelligent combination, along with efficient charging with the electric additional compressor (eZV) and exhaust air turbocharger helps ensure the hallmark AMG performance and driving dynamics but also cuts consumption and emissions at the same time. The four-door AMG GT53 accelerates from zero to 100 km/h in just 4.5 seconds, and achieves a top speed of 285 km/h.
The EQ Boost starter-alternator in the new AMG GT53 also generates the power for the 48 V on-board electrical system. This in turn uses a DC/DC converter to supply the conventional 12 V network for the lights, cockpit, infotainment displays and control units. Through the 48 V battery the battery capacity of the entire car is increased, which means that more electrical energy can be made available for new functions. The 48 V on-board electrical system thus also paves the way for the progressive expansion of infotainment and assistance systems.
The six-cylinder inline engine is coupled with the AMG SPEEDSHIFT TCT 9G transmission. In conjunction with the torque converter the transmission is tuned to the special requirements of this engine. On the other hand, the extremely fast and emotive gearshifting characteristic of an AMG model is also possible depending on the drive program.
Space as needed: four or five seats to suit requirements
When it comes to the seats, too, Mercedes-AMG proves that comfort and exclusivity need not conflict with a performance-oriented vehicle configuration. The driver’s and front passenger seat can be configured in different scenarios. The selection ranges from the sporty, comfortable seat and a seat with elegant diamond quilting to an extremely contoured performance seat with an integral head restraint.
The four-door AMG GT also offers different seating configurations to meet all demands for the rear, too. These range from an asymmetrically folding rear bench seat for the family to two variants with two individual seats respectively. The High-Class variant has everything a business saloon requires. The rear passengers can select diverse features via a touchpad screen integrated into the console between the seats. The features range from calling up the dynamism data via the AMG menu to controlling the ambient lighting or the climate control and seat heating.
The boot capacity of up to 395 litres is supplemented by around a further 60 litres beneath the boot floor. With the backrests folded down the capacity is up to 1324 litres. The wide load compartment opening makes it easier to load and unload luggage and other items. As an option, the large boot lid can be opened and closed with the HAND-FREE ACCESS feature via a movement with the foot beneath the bumper.
Display buttons and capacitive switches: the innovative centre console
Inspired by the two-door Mercedes-AMG GT, the centre console of the new 4-door model represents a further special feature.
A new and unique feature comes in the form of the colour display buttons, integrated into the distinctive and tailor-made trim element, for the integral display and control of the transmission logics, suspension, ESP®, exhaust system, start/stop function and rear aerofoil. With their TFT technology the display buttons use coloured, intuitively comprehensible symbols to show the function and are easy to operate with just a small tap of the finger.
