Mercedes-AMG GT 4-Door Coupe

The new AMG GT 4-Door Coupe delivers special driving experiences on all levels, and with a top speed of up to 195 mph it ensures superior performance in any situation. Powerful, up-to-date in-line 6-cylinder and V8 engines with outputs ranging from 429 hp to 630 hp allow completely new driving experiences and combine impressive performance with modern efficiency.

The interior of the first four-door AMG GT model is characterized by elegant coolness and also by ultra-modern features: innovative controls can be intuitively operated and configured as required. The blend of high individualization 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. Moreover, the latest addition to the family 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.

Clearly recognizable as a member of the AMG GT family, the new AMG GT 4-Door Coupe 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 Coupe.

The front view with a long hood and two powerdomes leaves no doubt that this is the most recent addition to the AMG GT family. The AMG 4-Door Coupe follows the design tradition of the successful AMG GT models: the powerful body exudes sportiness and motivation. Sensuous shapes with convex surfaces lend the four-door GT a timeless elegance, while a flowing silhouette with lowered greenhouse points to its sporting credentials. As in the AMG GT R, radiator shutters, known as the Airpanel, in front of the center cooling air inlet improves the car’s aerodynamic efficiency. Slim MULTIBEAM LED headlamps, AMG-specific grille, “Shark Nose” and front bumper with its enhanced Jet Wing (with a flowing A-Wing on the six-cylinder model) also lend the most recent model from Affalterbach the hallmark presence of the AMG GT family.

The exciting AMG 4.0-liter V8 biturbo engine is already used in numerous AMG models. Its output has been increased even further for the new Mercedes- AMG GT 63 S and ensures superior performance on a par with a sports car. It delivers 630 hp and a maximum torque of 627 lb.-ft., which is available over a wide engine speed range from 2,500 to 4,500 rpm. The top engine of the new four-door AMG GT delivers outstanding performance in every engine speed range. Acceleration from zero to 60 mph in 3.1 seconds (estimated) is proof positive of this, as is the maximum speed of 195 mph.

In the Mercedes-AMG GT 63, the V8 engine delivers 577 hp and 553 lb-ft of maximum torque. A sprint from zero to 60 mph takes just 3.3 seconds (estimated), with a top speed of 193 mph.

The AMG 4.0-liter V8 engine works with 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 engine 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.

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 utilized. Put together, these technologies both improved the immediate response of the four-liter, eight-cylinder engine from AMG, which was already the benchmark. Through the optimized cylinder charge, output and maximum torque was raised further. Spray-guided direct  fuel injection with piezo injectors, all-aluminum crankcase, four-valve-per- cylinder design with camshaft adjustment, an air-water intercooler, alternator management, ECO start/stop function and gliding mode have all been retained.

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 1,000 to 3,250 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 sacrifice any comfort.

Alongside the two V8 engines the new AMG GT 4-Door Coupe is also available as the Mercedes-AMG GT 53 with the innovative AMG AMG-enhanced 3.0-liter Inline-6 turbo engine with EQ boost. The 429 hp 3.0-liter unit is characterized by high performance, supported by an electric “EQ Boost” which offers an output of up to 21 hp and 184 lb-ft of torque. The EQ Boost starter-alternator combines a starter motor and alternator in a powerful electric motor and is positioned between the engine and transmission. This intelligent combination, along with efficient charging with the additional electric charge-air compressor (eZV) and exhaust air turbocharger helps ensure hallmark AMG performance and driving dynamics but also cuts consumption and emissions. The four-door AMG GT 53 accelerates from zero to 60 mph in just 4.4 seconds (estimated), and achieves a top speed of 174 mph.

The EQ Boost starter-alternator in the new AMG GT 53 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 interior presents a symbiosis of performance and exclusivity and  integrates an ultra-modern, new type of operating system into the atmosphere of a Gran Turismo. The sculptural instrument panel forms an interesting contrast here to the large trim element with its flowing style, which merges into the driver’s door in a wrap-around effect. Illuminated turbine-look air vents refine the high-quality impression and underline the sporty appearance. The eye-catching feature in all AMG GT interiors is the center console, with its stylized V8 design, putting the spotlight on the brand’s performance claim as well as optimally fulfilling functional requirements.

Two high-resolution displays, each measuring 12.3 inches, dominate the Widescreen Cockpit, which is standard on all AMG GT 4-Door Coupe variants in the US market. Three different styles are available for selection for these all- digital displays: “Classic,” “Sport” and the completely new “Supersport.” Depending on the driving style or interior equipment, the different styles can  be set at any time via the instrument cluster or the central display.

Via the left-hand Touch Control Button on the steering wheel, preferred information can be projected onto the left- or right-hand side of the instrument – for example, the classic speedometer and tachometer, information on navigation or assistance systems through to detailed engine data. Especially sporty drivers can also fade in a g-force display or the current output and torque values.

In the “Supersport” view, there is also extensive additional AMG-specific information, such as a prominent prompt to change up a gear in manual transmission mode, reminiscent of motorsport.

The central display represents the interface to all further content and information, such as navigation, radio, media, telephone and vehicle data. The large full-screen map view ensures optimum legibility in all driving situations. There are also extra performance-oriented functions, such as visualization of the all-wheel drive system’s power delivery.

Sales release of the first four-door AMG GT is in early 2019 for the AMG GT 63 and 63 S and in mid-2019 for the AMG GT 53.
