I am quite unsure why after building a sleek 2-door car, some companies decide to constantly add more doors. Take the 4-series from BMW, a sleek 2-door coupe only for them to create the Gran Coupe with 4 doors. Here now, Mercedes has taken their Mercedes-AMG GT and made a 4-door version. What were they thinking? Actually, it kind of grows on you.
More space, more power, more goose pimples – 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 of success. 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.
“The new AMG GT 4-Door Coupé blends the impressive racetrack dynamism of our two-door sports car with maximum suitability for everyday use. It has a unique way of embodying our brand core, “Driving Performance” and with its systematic configuration it will attract new customers for Mercedes-AMG”, commented Tobias Moers, CEO of Mercedes-AMG GmbH.
The new AMG GT 4-Door Coupé delivers special driving experiences on all levels and with a top speed of up to 315 km/h and its driving dynamics it cuts an effortlessly superior figure wherever it goes. Powerful, up-to-date 6-cylinder in-line and V8 engines with outputs ranging from 435 hp to 639 hp allow completely new driving experiences and combine impressive performance with modern efficiency.
The interior of the first four-door AMG GT model is characterised by elegant coolness and also the latest features: innovative control panels can be intuitively operated and configured as required. The blend of high individualisation and sports car technology, placing yet more focus on the requirements of discerning customers, is also clear from the wealth of equipment packages and individual options. The latest coup from Affalterbach also lives up to the Mercedes-AMG brand pledge with regard to its high driving dynamics and sets the benchmark in its segment on the racetrack too.
Clear at first sight: the AMG GT family membership
Clearly recognisable as a member of the AMG GT family, the new AMG GT 4-Door Coupé follows the design philosophy of Sensual Purity. It takes the striking proportions with convex surfaces and a muscular body and develops them to exciting effect for a four-door variant of an AMG GT Coupé.
Sensuous shapes with convex surfaces lend the four-door GT timeless elegance, whilst the flowing silhouette with the lowered greenhouse flags up its sporting credentials. As in the AMG GT R radiator shutters, the Airpanel in front of the centre cooling air inlet improves the car’s aerodynamic efficiency. Slim MULTIBEAM LED headlamps, the AMG-specific radiator protection grille, the Shark Nose and the front apron with its enhanced Jet Wing (with a flowing A-Wing on the six-cylinder model) also lend the youngest model from Affalterbach the hallmark presence of the AMG GT family.
With frameless side windows and a flat windscreen inclined far to the rear, features of the classic coupé architecture are also cited. With the additional seat row in the rear the characteristic lines of the AMG GT models are not compromised. The tailored upper contours and broad shoulders point to the athletic, sporty orientation of the car, which is additionally emphasised by very pronounced rear wheel arches.
The rear view of the new 4-door coupé picks up on familiar features of the AMG GT design idiom: extremely slim LED tail lights define the hallmark boot sill line, the rear aerofoil extendable in several stages not only underscores the family affiliation; it is also an important element of the active aerodynamics.
The two eight-cylinder models can be identified through the three horizontal louvres in the side front air intakes, the Jet Wing with its trim element in Silver Shadow, the distinctive diffuser on the tail end and the two-pipe exhaust system with trapezoidal tailpipe trims. The six-cylinder variant, meanwhile, has one louvre in each of the air inlet grilles, round twin tailpipe trims and a somewhat less pronounced rear diffuser.
“The new AMG GT 4-Door Coupé is the ultimate four-door sports car and the ideal ambassador for Performance Luxury”, said Gorden Wagener, Chief Design Officer Daimler AG. “It embodies a symbiosis of emotion and intelligence with breathtaking proportions and a puristic, surface-oriented design with sensuous shapes. It is both hot and cool at the same time.”
Visual emphasis on demand: the exterior packages
The new AMG GT 4-Door Coupé offers an extensive portfolio of exterior equipment packages, which can be used to add different highlights in terms of design. The Night Package comprises high-gloss black trim, whilst, for example, the Chrome package emphasises the luxurious character of the car with trim and an insert in high-gloss chrome. Two Carbon-Fibre Packages offer different versions of carbon-fibre trim, whilst the optional Aerodynamics package gives the car an even sportier look and is a new feature in this segment. It includes additional functional features in high-gloss black, the Jet‑Wing in Silver Shadow in the front apron and the fixed rear aerofoil and also naturally reduces lift at higher speeds. With the V8 style package the six-cylinder model can also be equipped with design features from the eight-cylinder versions.
Top sporting performance: V8 biturbo engines with up to 470 kW (639 hp)
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 GT 63 S 4MATIC+ (fuel consumption combined 11.2 l/100 km, CO2 emissions combined 256 g/km)* and ensures superior performance on a par with a sports car. It delivers 470 kW (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 GT 63 4MATIC+ (fuel consumption combined 11.0 l/100 km, CO2 emissions combined 252 g/km) the V8 unit provides 430 kW (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 GT 63 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 GT 63 can be equipped with active engine mounts as part of the Dynamic Plus package.
* The stated figures (provisional data) were determined in accordance with the prescribed measuring method. These are the NEDC CO2 figures according to Art. 2 No. 1 Implementing Regulation (EU) 2017/1153. The fuel consumption figures were calculated based on these figures.
Direct response: the two twin-scroll exhaust-gas turbochargers
Two twin-scroll exhaust-gas turbochargers combined with another innovative technology ensure even more output and better response. For the first time Mercedes-AMG is combining the advantages of twin-scroll technology in the V8 engine with turbine wheels mounted in anti-friction bearings. Through the mounting in anti-friction bearings, friction is reduced to an absolute minimum inside the exhaust-gas turbocharger. The twin-scroll technology also ensures that the exhaust gas flow is optimally utilised. Put together these both improved the immediate response of the four-litre eight-cylinder from AMG, which was already the benchmark. Through the optimised cylinder charge the output and the maximum torque was raised further. Spray-guided direct petrol injection with piezo injectors, the all-aluminium crankcase, the four-valve-per-cylinder design with camshaft adjustment, air-water charge air cooling, alternator management, the ECO start/stop function and the gliding mode have all been retained.
Improved efficiency: the intelligent AMG Cylinder Management
For maximum efficiency, Mercedes-AMG has also equipped the V8 engines with the AMG Cylinder Management cylinder deactivation system. In the partial-load range, cylinders two, three, five and eight are deactivated, which crucially reduces the fuel consumption.
When the driver has selected the “Comfort” drive program, the cylinder deactivation system is available in the wide engine speed range from 1000 to 3250 rpm. A special display on the instrument cluster states whether the cylinder deactivation system is in use and whether the engine is presently operating in the four- or eight-cylinder mode. The transition between these two operating states is immediate, fast and torque-neutral, so the occupants do not have to relinquish any comfort.
Powerful and versatile: six-cylinder engine with innovative hybrid function
Alongside the two V8 engines the new four-door sports car is also available as the Mercedes-AMG GT 53 4MATIC+ (fuel consumption combined 9.1 l/100 km, CO2 emissions combined 209 g/km) with the innovative AMG six-cylinder inline engine. The 320 kW (435 hp) 3.0-litre unit is characterised by high performance, supported by a boost effect with an output of up to 16 kW (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 GT 53 accelerates from zero to 100 km/h in just 4.5 seconds, and achieves a top speed of 285 km/h.
Emotive gearshifting experience: the AMG SPEEDSHIFT transmission
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.
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.
Optimum traction: rear-axle limited-slip differential
To improve traction and dynamism the AMG GT 63 S has an electronically controlled locking differential at the rear axle as standard. The slip is thus suppressed at the inner wheel on bends, ensuring optimum grip. The driver is therefore able to accelerate out of corners earlier and with more power thanks to the improved traction. The vehicle remains more stable when braking from high speed, while the limited-slip differential also improves traction when accelerating from rest. The electronic locking differential is part of the Dynamic Plus package and in this combination it is also optionally available for all further variants of the four-door AMG GT.
Enhanced agility and precision: the active rear-wheel steering
The AMG GT 4-Door Coupé responds even more sensitively to steering commands thanks to the active rear axle steering which comes as standard in the V8 models and is optional in the six-cylinder versions. The system facilitates an even better combination of agility and stability and thus reinforces the dynamism and the handling safety of the new AMG GT four-door model.
Up to a speed of 100 km/h, the rear wheels point in the opposite direction to the front wheels via two electric actuator motors. As a result, the car turns into corners with significantly higher agility. Under everyday driving conditions, the driver also benefits from a smaller turning circle.
At speeds higher than 100 km/h, the system turns the rear wheels in the same direction as the front wheels. That noticeably improves driving stability. At the same time, the lateral force on the rear wheels builds up considerably faster on changes of direction, thus improving the response to the steering. The driver can also rely on extreme rear-axle grip and high stability when changing direction quickly, without the usual tendency for the rear end to break out.
Good control and fade-resistant: the AMG high-performance braking systems
In line with the high output values and their associated performance the eight-cylinder models have a large-dimensioned brake system consisting of compound discs with 6-piston fixed callipers at the front and single-piston floating brake callipers at the rear. The S variant is characterised by yellow brake callipers, whilst the base variant of the eight-cylinder sports red brake callipers.
The six-cylinder model is also equipped with internally ventilated and perforated compound brake discs with brake callipers painted silver grey.
As an option a high-performance ceramic brake system with bronze-coloured 6-piston fixed callipers at the front and single-piston floating brake callipers at the rear can be ordered, saving weight compared with the compound discs and thus reducing the unsprung masses. Further advantages are their high overall and fading stability under high stress. The brake system also wins points with a high service life and immediate response – guaranteeing fast lap times.
Design and lightness: the new AMG wheels
To make a grand entrance – both visually and technically – the four-door AMG GT Coupé is shod in generous wheel/tyre combinations. The customer can choose from a multitude of aerodynamically optimised disc wheels between 19 and 21 inches. Alongside their visual design the developers Affalterbach placed great emphasis on reducing the unsprung masses. It is above all the light-alloy wheels produced using high-quality forging technology, which set the benchmark yet again with their extremely low weight.
The AMG GT 53 and GT 63 variants of the four-door AMG GT Coupé sport standard-specification 10-spoke disc wheels painted vanadium silver in the size 9.5 J x 19 H2 ET 22 and 255/45 R 19 tyres at the front, plus 11.0 J x 19 H2 ET 17 with the tyre size 285/40 R 19 at the rear.
The AMG GT 63 S 4MATIC+ wears light-alloy wheels with five twin spokes painted tantalite grey with a high-sheen finish, in the dimension 9.5 J x 20 H2 ET 22.5 with tyres 265/40 R 20 at the front, plus 11.0 J x 20 H2 ET 20 and tyres 295/35 R 20 at the rear.
Always in touch with Connectivity and Intelligent Drive
For high comfort in everyday use the new four-door sports car from Affalterbach boasts all the connectivity and Intelligent Drive functions and options of the Mercedes-AMG S-Class. These include partially automated driving with the DRIVE PILOT, which can support the driver with routine daily tasks such as driving in a traffic jam.
In addition to the standard functions of Mercedes me connect, such as eCall, Accident Recovery, Breakdown Assistance and Customer Service, Remote Online (included as standard with COMAND Online) offers a range of convenience features via smartphone. For example tracking the parked vehicle, controlling the auxiliary heating, locking/unlocking the vehicle and checking the status of the mileage, fuel level or range, for example, among other things.
The vehicle as a virtual race engineer: AMG TRACK PACE
With AMG TRACK PACE, drivers can feel like Formula 1 World Champion Lewis Hamilton, and capture and analyse in detail over 80 vehicle-specific data as well as times on the racetrack. AMG TRACK PACE is an additional function of the COMAND Online infotainment system and is part of the standard equipment for the AMG GT 4-Door Coupé.
Data collected on lateral and longitudinal acceleration, the accelerator and brake pedal or steering angle help record and continuously improve individual Driving Performance. All the values are shown on the COMAND display, on request also in real time on the telemetry screen. Thanks to the different colours and acoustic feedback used, faster or slower laps can be spotted out of the corner of the driver’s eye without any need to look away from the track. Even the drift angle of the car is calculated and displayed.
As well as recording drives on circuits, AMG TRACK PACE can also be used to register acceleration such as the sprint from standstill to 100 km/h or over a quarter of a mile as well as deceleration values.
