Concept AMG GT XX: Electric Sports Car Redefines Performance
The performance of tomorrow arrives today as Mercedes-AMG unveils the CONCEPT AMG GT XX, an electric sports car that blends breakthrough technology, relentless endurance and an arresting design. This pioneering programme previews a forthcoming four-door production model that will sit on the dedicated AMG Electric Architecture. Engineers in Affalterbach, Sindelfingen, Untertürkheim, Brixworth and at YASA in Oxford joined forces to craft a revolutionary drive system: three compact axial flux motors paired with a clean-sheet high-performance battery.
“The best minds in our global R&D network have contributed their extensive expertise – from Mercedes-Benz in Sindelfingen and Untertürkheim to Mercedes-AMG in Affalterbach and YASA in the UK to our Formula 1 drivetrain experts at Mercedes-AMG High Performance Powertrains in Brixworth. Together, they have developed the CONCEPT AMG GT XX and are providing an insight into pioneering drivetrain technology and the future of performance. The technology programme pushes the boundaries even further and ventures into new ground. The CONCEPT AMG GT XX with its three axial flux motors now lifts performance and endurance to a completely new level.” Markus Schäfer, Member of the Board of Management of Mercedes-Benz Group AG, Chief Technology Officer, Development & Procurement
“The CONCEPT AMG GT XX is the next milestone in the history of AMG and forges a whole new dimension of performance. We’re bringing groundbreaking technology that redefines high performance. And the best thing is that this car is a true AMG through and through. The heart of an AMG was always the motor, and that will remain so with our in-house electric architecture. With our high-tech axial flux motor, we’re delivering a revolutionary new drive that is unparalleled in terms of power density, weight and packaging. This pairs with a new performance battery developed from scratch that enables a previously unimagined level of performance and endurance.” Michael Schiebe, CEO of Mercedes-AMG GmbH and Head of Business Units Mercedes-Benz G-Class and Mercedes-Maybach
“With the CONCEPT AMG GT XX, we have succeeded in translating our design vision for AMG into the future. Sports cars have always been the icons of our brand; they are emotional and exceptional to create. They represent unique moments in time. Icons like the 300 SL and the legendary Silver Arrows are the emotional heart of our brand, as are the GT and AMG ONE. Crafting these masterpieces is about creating something extraordinary, from the C111 to the Vision One-Eleven, and into the future of production. The brand-new CONCEPT AMG GT XX embodies the hot part of our design philosophy of sensual purity.” Gorden Wagener, Chief Design Officer, Mercedes-Benz Group AG
Axial flux motors lie at the core of the CONCEPT AMG GT XX. Developed in collaboration with YASA, each disc-shaped unit delivers triple the power density of a conventional radial motor, while weighing two-thirds less and occupying just one-third of the space. Engineers package two motors and their planetary gears within a single rear High Performance Electric Drive Unit and place a third motor with spur-gear transmission on the front axle. The front motor engages only when extra traction or power is beneficial to efficiency, and a disconnect unit decouples it during steady cruising, thereby eliminating drag losses. Oil cooling for motors and gears, along with water-cooled silicon-carbide inverters, enables peak output exceeding 1,000 kW (1,360 hp) and propels the car beyond 360 km/h.
Mercedes-Benz builds these motors in Berlin-Marienfelde, utilising more than a hundred highly automated processes, thirty-five of which are introduced worldwide. Innovative laser techniques and AI-driven quality checks have earned over thirty patent applications, underscoring the plant’s status as a hub for powertrain innovation.
A completely new high-performance electric Battery supports the motors. The pack contains over 3,000 tall, slim, cylindrical cells with NCMA cathodes and silicon-enhanced anodes, locked in a laser-welded aluminium housing that improves conductivity and sheds unnecessary kilograms. Full-tab architecture reduces internal resistance and enhances durability, while direct oil cooling surrounds every cell to maintain ideal temperatures for rapid discharge and ultra-fast charging. Operating at voltages above 800 volts, the battery accepts more than 850 kW at 1,000 amperes, adding approximately 400 km of WLTP range in about five minutes. Mercedes-AMG co-developed a prototype 1,000-A CCS charger with Alpitronic and will roll out similar hardware across its high-power network.
The body-in-white, built on AMG EA’s skateboard, combines aluminium, steel, and composite materials to achieve extreme torsional stiffness with minimal mass. Engineers integrate the battery as a structural member, create defined crash paths and route high-voltage cabling for maximum safety.
Visually, the car announces itself with a low bonnet, a sharply raked windscreen, and a dynamic fastback painted in Sunset Beam Orange that shimmers like liquid metal. A concave Panamericana-style grille with ten vertical struts frames stacked rectangular headlights, while bonnet air outlets expel heat from horizontal radiators. Deep side sills, recessed handles, and broad shoulders flow into a tapering rear without a window, allowing for a low deck and a wide diffuser inspired by the AMG ONE. Aerodynamic sculpting, an optimised underbody Venturi i, and active AIRPANEL shutters deliver a drag coefficient of just 0.198, despite wide performance tyres.
At speed, active aero elements further boost efficiency and stability. The 21-inch forged Aero Wheel addresses the trade-off between brake cooling and drag by opening five movable blades when a sensor detects the need for airflow; each wheel’s self-powered actuator stores energy for up to 200 actions and communicates via Bluetooth.
Inside, motorsport minimalism meets luxury craft. Black dominates; raw aluminium, carbon fibre and backlit orange piping evoke high-voltage lines. Two glass-fronted displays—a 10.25-inch cluster and a 14-inch touchscreen—tilt towards the driver and run a bespoke MB.OS interface that animates battery and drivetrain data. A near-rectangular steering wheel features paddles for recuperation and illuminated AMG buttons. Body extrusions frame the centre console and display a solid-metal AMG coat of arms. Lightweight carbon bucket seats feature bespoke 3D-printed pads wrapped in LABFIBER Biotech Leather Alternative, made from upcycled racing tyres. Meanwhile, door pulls utilise biotech silk yarn, boasting the sheen of natural silk while being fully biodegradable.
Exterior innovation continues with electroluminescent paint along the sills. During charging, illuminated segments extinguish sequentially, signalling progress before the GT XX silently unleashes full power. Engineers also mount exterior speakers within the headlight housings to broadcast distinctive driving sounds and pedestrian alerts without extra cavities. At the rear, a Fluid Light Panel features over 700 programmable RGB LEDs, displaying animations such as the AMG logo or charging status in crisp 3D pixel form.
The fully variable AMG Performance 4MATIC+ all-wheel system orchestrates torque across front and rear axles in milliseconds, blending tail-happy agility with assured traction. Continuous software control leverages a comprehensive vehicle matrix to transition seamlessly between rear-drive thrills and all-wheel security.
By marrying three groundbreaking axial flux motors, a race-bred battery, intelligent aerodynamics and cutting-edge sustainable materials, the CONCEPT AMG GT XX proves that the electric sports car can exceed the emotional and dynamic standards long set by AMG combustion icons.
