AMG's Electric GT Aims For Repeatable Pace

Mercedes-AMG has taken the four-door GT into a new register. The latest GT 4-Door Coupé arrives as a full-blooded electric performance car, but the familiar AMG trick remains intact. The numbers are properly lurid. Up to 860 kW, three axial-flux motors, an 800-volt battery developed with the sort of thermal discipline usually associated with an F1 pit wall, and charging claims that would make a long-distance road trip feel less like planning and more like interruption management. Yet the more interesting part is how deliberately Mercedes-AMG has shaped the whole package around repeatable pace, not one heroic pull followed by a fade.

The new Mercedes‑AMG GT 4‑Door Coupé ushers in an entirely new era. It is an absolute high-performance machine, packed with pioneering innovations that enable previously unimaginable driving performance in this segment. It creates a driving experience that is unparalleled: thrilling, intense, irresistible – typically AMG. The pride and spirit of our AMG team are reflected in every detail. I thank all colleagues for their enormous dedication, which makes this vehicle an absolutely revolutionary, breathtaking product

A new AMG architecture

The GT 4-Door Coupé is the first series-production AMG EV to use axial-flux motors, and that alone tells you where Affalterbach wants to sit in the electric arms race. Two motors live at the rear, one at the front. The layout gives the car fully variable all-wheel drive, torque vectoring at the rear, and the kind of control logic AMG can use to shift the car from calm to feral without making the transition feel clumsy.

In GT63 form, the car produces up to 860 kW during Launch Control at 80% state of charge. 530 kW is available all the time. The GT 55 is hardly a soft option either, with 600 kW (375 kW continuous). Torque peaks at 2 000 N.m in the GT 63 and 1 800 N.m in the GT 55. Both versions top out at 300 km/h with the Drivers Package. The sprint from 0 to 100 km/h is achieved in just 2,4 seconds, while the EV requires only 6,8 seconds to reach 200 km/h in the GT63. The same tests take the GT55 2,8- and 9,0 seconds, respectively.

The front motor is used as a booster unit, then disconnected in milliseconds when the car does not need it. That helps reduce drag losses. The rear axle unit carries two motors and a single-stage planetary gearbox. Mercedes-Benz says the production process for the axial-flux motors at Marienfelde in Berlin involves around 100 manufacturing steps, with 65 of them new to the company and 35 classed as world firsts.

The battery is the point

The battery is where the AMG story becomes properly interesting. It is a new 800-Volt lithium-ion pack, built from the same philosophical rootstock as the Mercedes-AMG One and the Concept AMG GT XX record programme. The cell architecture uses 2 660 cylindrical cells, each directly cooled by electrically non-conductive oil. The pack is divided into 18 laser-welded modules, and the cells themselves are 105 mm high and 26 mm in diameter.

That shape matters. Shorter heat paths mean faster thermal control, and faster thermal control means the battery can keep delivering rather than sulking after one hard launch. AMG also uses NCMA chemistry, a silicon-rich anode, and lightweight aluminium cell housings to improve energy density, charging behaviour, and service life.

Mercedes-AMG claims the pack can take more than 800 amperes and over 600 kW at the right charger. The headline figure is about 460 km of range added in 10 minutes, with a 10 to 80% charge taking 11 minutes. Total range for the GT63 is rated between 664-764 km. It also works on 400-Volt infrastructure. The battery is integrated into the structure of the car, protected in a crash-ready safety box and tied into the body-in-white for rigidity.

AMG still wants drama

Electric drivetrains often arrive with all the emotion of a spreadsheet. AMG clearly knows that. The GT 4-Door Coupé gets AMG Force S+, a mode that leans into the V8 era with simulated gearshifts, an immersive soundscape, and a central-tube style driver display. Mercedes-AMG says the sound system draws from more than 1 600 files, with the AMG GT R acoustic character used as the base. It adds approach sounds, entry sounds, locking heartbeats, charging noises, and planned Launch Control, Boost and Showtime effects.

The adjustable character goes deeper than sound. AMG multiple variable drivetrain system splits control into response, agility and traction tuning. Response changes accelerator sharpness. Agility alters yaw behaviour and torque distribution. Traction control is adjustable in nine stages. That is the sort of calibration range that lets a driver build confidence without being bullied by the hardware.

There are seven AMG Dynamic Select modes, including Comfort, Sport, AMGForce Sport+, Race, Slippery, Individual and, for the first time at AMG, Eco. The last one is especially telling. It trims consumption, lowers the body, uses rear-wheel drive for efficiency, and helps stretch the battery toward the next charge point. Even the most extroverted AMG in history still has to think about range.

Suspension and aero do the heavy lifting

The GT 4-Door Coupé also gets AMG Active Ride Control suspension with semi-active roll stabilisation, triple-adjustable air springs and an 8,2-litre pressure reservoir. The system uses hydraulically linked struts instead of conventional anti-roll bars, which lets the car soften itself over broken surfaces and then tighten up when the road starts to flow. On South African roads, that kind of duality matters more than any number published in a glossy launch deck.

Active rear-axle steering turns the rear wheels opposite to the fronts at low speeds, then in the same direction above that point, with up to 6 degrees of rear steer. The result should be a car that feels smaller in tight spaces, cleaner in quick direction changes, and more settled when the road opens up.

Aerodynamics are active too. The front and central Venturi elements drop from 120 km/h and 140 km/h respectively to increase downforce. The rear spoiler changes angle as speed rises, and can be set manually for maximum stability. The Airpanel system keeps the louvres shut for range, then opens them in nine stages when cooling demand rises. AMG says the drag coefficient is 0,22, while the body sits 40 mm lower than the previous car despite the battery under the floor.

The styling suits the brief. Long bonnet, steep screen, broad shoulders, fastback tail, turbine-style rear lamps and the optional illuminated grille all push the same message. This is an electric car, yes. But it is still meant to look like it was built to cover ground at indecent speed.

The cabin keeps the driver central

Inside, AMG has resisted the temptation to turn the cabin into a rolling tablet demo. The seating position is low, the screens are wrapped into a wide glass surface, and the driver gets a 258 mm instrument display alongside a 356 mm central screen. An optional 356 mm passenger display is available, but the whole layout stays driver-centric.

The AMG Special display theme adds a proper performance layer, and AMG Track Pace records more than 80 data points ten times per second for those who use their fast car properly. The rear seats are positioned for grand touring comfort, there is a panoramic roof, and the trim palette can move from performance-focused to full Manufaktur individualisation.

Mercedes-AMG says production starts in summer 2026 at Sindelfingen. By then, the market will have had time to decide whether 860 kW and a genuinely usable electric chassis feel like the future, or just the most convincing argument yet for it.
