Mercedes-AMG GT 4-Door Coupe unveiled, makes 1,169bhp and features axial-flux motors

The all-new Mercedes-AMG GT 4-Door Coupe marks a significant moment for Mercedes-AMG as the brand steps decisively into the electric performance era. Built on the brand’s new dedicated AMG.EA architecture, the four-door electric sports car combines unprecedented performance figures with advanced battery technology, active aerodynamics and a deeply emotional driving experience engineered to retain AMG’s signature character.

At the heart of the new GT 4-Door Coup lies a revolutionary drivetrain concept featuring three axial-flux electric motors, two mounted at the rear axle and one at the front. Developed using technology from British electric-motor specialist YASA, the setup delivers up to 1,169bhp in the flagship GT 63 4-Door Coup 4MATIC+, while the GT 55 4-Door Coup 4MATIC+ produces 816bhp.

Performance figures are extraordinary. The range-topping GT 63 accelerates from 0-100kmph in just 2.1 seconds and reaches 200kmph in 6.4 seconds, with a top speed of 300kmph when equipped with the optional Driver’s Package. More importantly, AMG claims the powertrain is designed to repeatedly deliver peak performance without thermal degradation, a major step forward for high-performance EVs.

A key highlight is the newly developed AMG High Performance Electric Battery (HP.EB), inspired by lessons learned from the Mercedes-AMG ONE and Formula 1 technology. The 800-volt battery pack uses 2,660 directly cooled cylindrical cells with a unique tall and slim design, aluminium housings and NCMA chemistry.

The battery features direct oil cooling for each individual cell, enabling consistent thermal stability during aggressive driving and repeated high-speed acceleration runs. AMG says the setup ensures both exceptional continuous power delivery and ultra-fast charging capability.

Charging performance is equally headline-grabbing. The GT 4-Door Coup supports up to 600kW DC fast charging, allowing more than 460km of WLTP range to be added in just 10 minutes. A 10-80 percent charge can reportedly be completed in only 11 minutes under optimal conditions.

Axial-flux motors bring a new era of AMG performance

Unlike conventional radial electric motors, axial-flux motors use a compact disc-shaped layout that delivers significantly higher power density and torque. The front motor acts primarily as a booster unit and can disconnect itself during cruising to improve efficiency.

The rear electric drive unit integrates two axial-flux motors with a compact planetary gearbox, while silicon-carbide inverters help maximise thermal efficiency and performance. AMG says the drivetrain architecture is already capable of handling outputs beyond 1,000kW in future applications.

AMG promises authentic V8 emotion

Despite being fully electric, AMG has gone to extraordinary lengths to preserve the emotional appeal associated with its V8-powered models. The new AMGFORCE S+ mode introduces simulated gearshifts, traction interruption effects and a specially developed V8-inspired acoustic experience.

AMG says more than 1,600 sound files are processed in real time to create dynamic engine-like acoustics depending on throttle input, acceleration and driving conditions. The system even recreates burbles, shift impacts and launch-control theatrics designed to mimic the feel of a traditional AMG V8 sports car.

Advanced chassis and active aerodynamics

The GT 4-Door Coup comes equipped with AMG Active Ride Control suspension featuring semi-active roll stabilisation and hydraulically interconnected dampers. Rear-axle steering with up to 6 degrees of movement improves both agility and high-speed stability.

Aerodynamics also play a critical role. The car debuts active underbody Venturi-flow aero elements, an active rear diffuser and a deployable rear spoiler that continuously adjusts depending on speed and driving conditions. AMG claims these systems significantly improve downforce, cornering stability and efficiency.

The AMG Performance 4MATIC+ all-wheel-drive system works alongside torque vectoring to precisely distribute power between all four wheels and even individually across the rear axle for maximum traction and dynamic capability.

Radical design with futuristic cockpit

Visually, the new AMG GT 4-Door Coup adopts dramatically taut proportions with a low-slung roofline, muscular rear haunches and an aggressive fastback silhouette. The illuminated AMG grille, star-shaped daytime running lights and six circular turbine-style taillights give the car a futuristic yet unmistakably AMG identity.

Inside, the cabin blends sports-car focus with grand-tourer comfort. A 10.2-inch instrument cluster and 14-inch central touchscreen sit beneath a seamless glass panel, while an optional passenger display adds additional digital functionality. AMG-specific controls, performance telemetry, AI-powered MBUX features and track-focused software such as AMG TRACK PACE further reinforce the car’s high-tech positioning.

The interior also features AMG Performance seats, extensive ambient lighting, a panoramic "Sky Control" glass roof and a highly configurable driving setup system via AMG Race Engineer \controls.

Production to begin in 2026

The new AMG GT 4-Door Coupe will enter production in summer 2026 at the Mercedes-Benz Sindelfingen plant. Meanwhile, the advanced axial-flux motors will be manufactured at the Mercedes-Benz Berlin-Marienfelde plant using several newly developed production processes and AI-supported manufacturing technologies.
