Mercedes-AMG has pulled the covers off the new GT 4-Door Coupe, an all-electric four-door that the brand says marks the start of a new era for its performance division.
It launches in two forms. The GT 63 4-Door Coupe produces up to 860kW and 2,000Nm, while the GT 55 4-Door Coupe makes 600kW and 1,800Nm. Both run a trio of axial flux motors, two on the rear axle and one at the front, driving through AMG’s fully variable Performance 4MATIC+ all-wheel drive.
The numbers are firmly in supercar territory. The GT 63 covers 0-100km/h in 2.1 seconds and 0-200km/h in 6.4 seconds on the one-foot rollout measure, with top speed pegged at 300km/h when the optional Driver’s Package is fitted. The GT 55 manages the 0-100km/h sprint in 2.5 seconds.
Three motors, an F1-derived battery
The axial flux motor design comes from British specialist YASA, which Mercedes-Benz acquired outright in July 2021. The format runs the electromagnetic flux parallel to the motor’s axis of rotation rather than perpendicular to it, allowing a far more compact unit. AMG says the result delivers higher continuous power and torque than conventional electric motors, and can repeat hard performance runs without fading.
Underpinning that is a newly developed 800-volt battery that AMG traces back to its Formula 1 programme and the AMG ONE hypercar. It uses 2,660 tall, slim cylindrical cells with NCMA chemistry and a silicon-bearing anode, each individually bathed in a non-conductive cooling oil. Net capacity is 106kWh, good for a WLTP range of 596 to 696km in the GT 63 and 597 to 700km in the GT 55.
Charging is where the technology really stretches ahead of current infrastructure. On a suitable 600kW charger the car can add around 460km of range in 10 minutes, with a 10 to 80 percent top-up taking just 11 minutes. It is also set up for the major fast-charging standards worldwide, including CCS2, GB/T, CHAdeMO, CCS1 and NACS, and can drop back to 400-volt charging where needed.
A synthesised V8 and serious hardware
For buyers who will miss the noise, AMG has built in a patent-pending soundtrack. The ‘AMGForce S+’ drive mode serves up a synthesised V8 spectacle drawn from more than 1,600 sound files, complete with simulated gear changes and a momentary cut in drive to mimic shifts. A sound slider lets owners dial the character between Powerful, Balanced and Minimal, and from Classic to Futuristic.
Chassis hardware is comprehensive. AMG Active Ride Control air suspension with semi-active roll stabilisation is standard, hydraulically linking the dampers in place of conventional anti-roll bars. There is rear-axle steering of up to six degrees, active Aerokinetics aerodynamics including underbody venturi panels and an extending rear spoiler, and a composite brake setup combining carbon-ceramic front discs with steel rears.
Inside, the cabin keeps a low-slung sports car seating position alongside grand tourer space in the rear. A seamless glass display unit houses a 10.2-inch driver cluster and 14.0-inch central screen, with an optional passenger display. Three haptic rotary controllers on the centre console form what AMG calls the Race Engineer Control Unit, governing throttle response, cornering balance and traction. The latest MBUX system folds in ChatGPT, Microsoft Bing and Google Gemini.
Group chairman Ola Kallenius, who has driven the car, says it “pushes performance to new limits and delivers the emotion our fans expect, now in the electric era.”
Production begins in summer 2026 at the Sindelfingen plant in Germany, with the axial flux motors built at Berlin-Marienfelde. Mercedes-AMG has not confirmed pricing, saying only that it will be based on comparable predecessor models. New Zealand availability is yet to be announced.
