Mercedes-AMG is getting ready to bring the GT 4-Door Coupé into its electric era, with a new model built from the start as a high-performance EV on the AMG.EA platform. When ordering opens, it will be available in two versions: the Mercedes-AMG GT 63 4-Door Coupé 4MATIC+ and the Mercedes-AMG GT 55 4-Door Coupé 4MATIC+.
Rather than adapting electric hardware from another model, AMG has built a new drive system for this car, using three axial-flux motors: two at the rear and one at the front. This gives the GT all-wheel drive while putting most of the power through the rear axle. In the GT 63, output can reach 860 kW, or 1,169 hp, when AMG Launch Control is used with the battery at 80% charge. The GT 55 is the less powerful version, with 600 kW, or 816 hp.
The numbers put the GT 63 firmly in supercar territory, despite its four-door body. It reaches 100 km/h from rest in 2.1 seconds and 200 km/h in 6.4 seconds, and, with the optional Driver’s Package, the top speed is 300 km/h. AMG has also put a lot of emphasis on charging performance, with the car able to add around 460 kilometres of range in ten minutes on a suitable 600 kW charger, while a 10% to 80% charge takes 11 minutes.
A recognisable look
The new AMG GT 4-Door Coupé keeps the elongated shape associated with the model, but the switch to an electric platform has changed its proportions. Even with the battery mounted under the floor, the car sits 4 cm lower than its predecessor, with a long front section, a steeply raked windscreen and a roofline that runs into a fastback rear. At the front, the AMG grille has vertical slats and a more concave shape, and it can now be ordered with illumination for the first time. The Mercedes star in the centre is illuminated as well, while the headlamps use star-shaped daytime running lights. The bonnet keeps the two power domes, a clear AMG reference carried over from the combustion models.
From the side, the car is defined by its long wheelbase, large wheels (which range in size from 19 to 21 inches), short overhangs and shallow glasshouse. The mirrors are mounted on the doors, and the flush door handles help smooth the airflow along the body. At the rear, there are broad shoulders, six circular tail lights with turbine-style graphics and an optional light strip that also works as a tail light. A gloss-black lower band runs around the car, linking the front splitter, side sills and rear section.
A lot of the bodywork is shaped around aerodynamics. Under the car, active AEROKINETICS parts include two movable venturi flow plates, which help manage the air passing below the body. The front plate deploys from 120 km/h, while the central plate deploys from 140 km/h, increasing downforce as speed rises. At the rear, an active diffuser works with an extendable spoiler, which stays hidden at low speed before moving through different angles from 80 km/h, depending on speed, acceleration and driving style. The driver can also raise the spoiler manually using a display button on the steering wheel.
Cooling is managed by the active Airpanel system, supported by vertical louvres that sit behind the front air intake and, on this model, also behind the left and right brake-cooling intakes. They usually stay closed to reduce drag and help range, then open when the battery, drive units or cooling system needs more air.
A sporty cabin designed to be luxurious
The cabin was designed around the low height of the car, making it more similar to that of a sports car than of a conventional one. The dashboard is dominated by a wide display split between the driver and passenger zones: the driver gets a 10.2-inch instrument cluster and a 14.0-inch multimedia screen, with the main centre screen angled towards them, while the passengers can enjoy a separate 14.0-inch display. At the outer edges of the dashboard are large round air vents with a chain-link design, integrated with the ambient lighting so they can glow in colours chosen by the occupants.
The centre console follows the angle of the main screen and carries three rotary controls for the AMG RACE ENGINEER functions, covering response, cornering behaviour and traction or slip settings. It also includes a closed storage compartment, two inductive smartphone charging trays and two illuminated cupholders. At the front of the console, around the central air vent housing, there is a winglet with a real-metal look.
The front seats are newly developed and shaped to support the body during hard cornering. AMG Performance seats are available as an option and come with integrated head restraints, while their backrests have two openings with galvanised trim inserts. The seat finishes range from more performance-focused choices to more comfort-led options, with the MANUFAKTUR programme adding further colours, materials and handcrafted elements. Rear passengers sit in two individual seats as standard, with recesses in the floor that Mercedes-AMG calls “foot garages” that offer more legroom and a relaxed knee angle. A three-seat rear bench is optional, and, in both layouts, the rear seatbacks can be split and folded.
Above the cabin, the SKY CONTROL panoramic glass roof is made from one large panel that runs back towards the rear window, with sections that can switch between clear and opaque. At night, optional lighting can add illuminated AMG crests above the front seats and racing-stripe graphics across the roof. The glass is designed to control heat, using heat-insulating laminated safety glass, an infrared-reflective coating and a LowE inner coating to reduce heat gain in summer and heat loss in winter. In selected markets, Mercedes-AMG will also offer an ultralight carbon-design roof.
The AMG Performance steering wheel has a flat lower section, rollers, paddles and two round AMG control buttons with small OLED displays. The rim can be finished in leather, carbon or MICROCUT microfibre, while the paddles are used to adjust recuperation, letting the driver choose how much energy the car recovers when slowing down. The doors have floating-style armrests, built-in grab handles and diamond quilting on the centre sections, with the seat controls placed in the quilted area above the armrest. With the optional Burmester High End 4D sound system, the speaker grilles are made from stainless steel.
Precise engineering for a smooth driving experience
The drive system uses axial-flux motors from YASA, the British electric motor specialist Mercedes-Benz has owned since 2021. In simple terms, an axial-flux motor is arranged differently from a more common electric motor: the electromagnetic flux runs along the axis of rotation rather than across it, and the main parts are set out as thin discs, with two rotors sitting on either side of the stator. That layout allows the motor to be compact while still producing high torque and holding strong output over time, with the front motor measuring about nine centimetres wide and each of the two rear motors about eight centimetres wide. At the rear, the two motors sit in a high-performance electric drive unit with a compact single-stage planetary gearbox, oil cooling and two water-cooled silicon-carbide inverters. At the front, the drive unit has one axial-flux motor, a spur-gear transmission, a parking lock, a silicon-carbide inverter and a pump control unit.
The front motor is not always doing the same work as the rear motors. It acts more like a booster, coming in when the car needs extra power or more traction, then disconnecting within milliseconds under lighter loads through a Disconnect Unit. That reduces drag when the car is cruising steadily or coasting. The two rear motors remain the main part of the drive system, and torque vectoring can distribute power between the rear wheels to control how the car puts its output onto the road.
The battery is a new AMG High Performance Electric Battery, developed using knowledge from Mercedes-AMG, Mercedes-AMG High Performance Powertrains in Brixworth and the AMG ONE programme. It uses 2,660 cylindrical cells, arranged in 18 laser-welded plastic modules. Each cell is 105 mm high and 26 mm wide, with a slim shape that reduces the distance between the core of the cell and its outer surface. That shorter distance helps with heat management, which is especially relevant in a car built for repeated hard acceleration, heavy recuperation and fast charging. The cells also use an aluminium housing instead of steel, which lowers weight and improves thermal and electrical conductivity. Inside, a full-tab design reduces internal resistance, while the cell chemistry uses NCMA cathodes and a silicon-containing anode. Mercedes-AMG quotes cell-level energy density at more than 298 Wh/kg or 732 Wh/l.
Cooling is built directly into the battery modules, as a non-conductive oil flows around each cell, helping to keep temperatures even when the battery is under heavy load, recovering energy or charging quickly. The car runs on an 800-volt electrical system, which helps reduce cable weight, charging losses and charging time. It can also switch to 400-volt charging when the infrastructure requires it, and the system is prepared for CCS2 in Europe, GB/T in China, CHAdeMO in Japan, CCS1 in South Korea and NACS in the USA.
The chassis comes with AMG ACTIVE RIDE CONTROL air suspension as standard, including semi-active roll stabilisation. It uses triple-adjustable air springs and hydraulic elements instead of conventional anti-roll bars, while an 8.2-litre pressure reservoir lets the car raise and lower quickly, with the ride height changing according to speed. Multi-link axles are used at the front and rear. Most of the main front suspension parts are made from forged aluminium, while the rear uses steel links with aluminium spring links. The rear-axle steering can turn the rear wheels by up to 6 degrees: below 80 km/h, they turn against the front wheels to reduce the turning circle and make the car feel shorter, while above 80 km/h, they turn with the front wheels by up to 1 degree to improve stability.
AMG Performance 4MATIC+ all-wheel drive varies torque between the front and rear axles, and also between the two rear wheels. Each motor is controlled independently, so the system can react quickly when the car detects a slip on rain, snow or ice. Braking uses a composite hydraulic system, with carbon-ceramic brakes at the front and steel brakes at the rear. The pedal is designed to feel consistent whether the car is slowing through recuperation, the friction brakes or a mix of both.
Amenities, upgrades and technology
Inside, the car uses the Mercedes-Benz Operating System as the base for its MBUX infotainment system, with the Zero Layer home screen putting common functions, suggestions and recently used apps in one place. Live Traffic Information is also included with the connected services. The MBUX Virtual Assistant uses AI from ChatGPT, Microsoft Bing and Google Gemini, appearing as an animated avatar and handling more natural voice conversations than a conventional command system.
AMG adds its own software on top of that, which comes in the form of the AMG Performance Menu, where live information from the drive system, including energy flow between the motors, active aero positions, battery status, tyre data, component temperatures, suspension information and lateral acceleration, can be found. AMG Set-Up gives the driver control over steering wheel shortcuts, drive functions, aero behaviour and the active rear spoiler, while a Pre-Check mode can deploy the active aero parts when the car is stationary.
The AMG TRACK PACE is included for circuit driving, which records more than 80 vehicle data points ten times per second, then shows lap times, sector times, telemetry and acceleration data through the main displays and the head-up display. Circuits such as the Nürburgring and Spa-Francorchamps are preloaded, and drivers can also record their own tracks. The head-up display can show cornering angles and braking points, and with the optional dashcam, track footage can be saved to a USB with data overlays. The Predictive Performance Manager works alongside this on circuits, using Endurance and Hotlap modes to manage energy use, saving power where full output is not needed and releasing more where it can improve lap time.
There are seven AMG DYNAMIC SELECT drive programmes: Comfort, Sport, AMGFORCE Sport+, RACE, Slippery, Individual and Eco. These change the accelerator response, suspension, steering, ESP, sound and recuperation. Eco is set up for range, reducing power and torque, lowering the top speed, using rear-wheel drive where possible and lowering the body to cut drag.
AMGFORCE Sport+ gives the electric car a programmed V8 character with more than 1,600 sound files mixed in real time, taken from the AMG GT R. The system also adds simulated gearshifts, brief traction interruptions during those shifts, a central-tube driver display and sound inside and outside the car. AMG Launch Control is available in Sport, Sport+ and RACE, and when it is activated, the seatbelts tighten, the ambient lighting changes, a build-up sound plays and the car vibrates before launch. In Comfort, Sport and Sport+, pulling both steering wheel paddles gives extra boost power: up to 110 kW in the GT 63 and up to 50 kW in the GT 55.
Production is due to start in summer 2026 at Mercedes-Benz’s Sindelfingen plant, while the axial-flux motors will be made at the company’s Marienfelde plant in Berlin using new processes such as laser work, joining techniques and some AI-supported manufacturing.
