The all-new AMG GT 4-Door Coupe is the first series-production car to use axial flux motors, producing up to 1,169hp in the range-topping GT 63 specification.
Its 800V battery supports 600kW DC charging, replenishing 460km of range in just ten minutes and completing a 10-to-80 per cent charge in 11 minutes.
Mercedes-AMG has revealed the second-generation GT 4-Door Coupe, and it marks a definitive turning point for the brand. Gone is the twin-turbocharged V8 that defined the outgoing model.
In its place sits an entirely new all-electric powertrain built on the AMG.EA platform, making the new car not just the most powerful four-door AMG ever produced, but one of the most technically sophisticated electric performance cars in existence.
Performance Figures That Redefine What a Four-Door Can Do
GT 63 Delivers 1,169hp and a 2.1-Second Sprint
The new GT 4-Door Coupe is offered in two variants. The GT 63 features three axial flux motors, two at the rear axle and one up front, producing a combined peak output of 1,169hp. It dispatches the 0-100kph sprint in 2.1 seconds with launch control engaged and reaches 200kph in just 6.4 seconds.
The GT 55, meanwhile, produces 816hp and completes the century sprint in under three seconds. Both variants are capable of reaching 300kph with the optional Driver's Package fitted. WLTP-rated range stands at 700km for the GT 55 and 696km for the GT 63.
The boost duration is tied directly to each variant's name. The GT 55 sustains peak power for 55 seconds, while the GT 63 holds it for 63 seconds. Pulling both steering wheel paddles simultaneously unlocks a further 150hp on demand.
A Battery That Changes the Charging Conversation
600kW Peak Charging via Direct Oil-Cooled Cells
Underpinning both variants is an 800V battery architecture housing 2,660 cylindrical cells submerged in electrically non-conductive oil for direct thermal management. This setup enables a peak DC charging rate of 600kW, sufficient to add 460 kilometres of range in ten minutes flat.
A full charge from 10 to 80 per cent takes just eleven minutes. The continuous power output sits at 721hp, which AMG says is sustainable through repeated track use.
The axial flux motors themselves are a first for any series-production road car. Co-developed with British specialist YASA, which AMG acquired in 2021, these motors place electromagnetic flux parallel to the axis of rotation rather than perpendicular, resulting in extraordinary power density within a remarkably compact package. Each rear motor occupies just eight centimetres of width; the front unit measures nine centimetres.
The V8 That Lives On in Sound and Sensation
Over 1,600 Audio Files Recreate the AMG GT R's Engine Note
Perhaps the most talked-about feature on the new car has nothing to do with charging or power output.
In AMG FORCE S+ mode, the car plays a synthetic V8 soundtrack assembled from over 1,600 audio recordings sourced from the AMG GT R. The experience includes haptic gear-shift interruptions through the steering paddles to mimic a twin-clutch transmission, a tachometer displayed on the central screen, and ambient sounds that respond contextually to driving inputs, from hard acceleration to a gentle trailing throttle.
AMG holds a patent on the system and has reportedly had its own engineers mistake it for the real thing.
Design and Dynamics Built Around a Lower, Wider Stance
Sits 4cm Lower Than the Outgoing V8 Model
Despite housing a substantial underfloor battery, the new GT 4-Door Coupe sits 4cm lower than its predecessor, measuring 1,411mm tall across a body 5,094mm in length.
The drag coefficient is a notably low 0.22 Cd. Kerb weight stands at 2,460kg. At the front, a concave grille with vertical slats, an illuminated Mercedes star, and a distinctive star daytime-running light signature establish an unmistakable identity.
At the rear, six circular turbine-design taillights carry a star graphic lineage traceable to AMG's recent concept cars.
The suspension does away with conventional anti-roll bars entirely, replacing them with semi-active hydraulically interconnected dampers that adjust continuously between comfort and cornering stiffness.
Rear-axle steering moves up to six degrees in either direction, sharpening turn-in below 80kph and improving high-speed stability above it. Torque vectoring between the two rear motors eliminates the need for a traditional rear differential.
Inside, a seamless glass display merges a 10.2-inch instrument cluster with a 14-inch multimedia screen. Three physical rotary dials form the AMG Race Control Unit, tuning response, agility, and traction across nine stages. Boot capacity is 507 litres, supplemented by a 62-litre front storage compartment.
