Mercedes-AMG has revealed the CONCEPT AMG GT XX, a fully electric four-door performance prototype that combines axial flux motor technology, Formula 1-inspired battery design, and active aerodynamic features in a preview of the brand’s future high-performance electric vehicles. The concept is scheduled to enter series production in 2026 on AMG’s dedicated electric vehicle platform, AMG.EA.
Powered by three axial flux motors – two at the rear in a High Performance Electric Drive Unit (HP.EDU) and one at the front for boost functionality – the drivetrain system delivers over 1,000 kW. The motors were developed by YASA, a British e-motor firm acquired by Mercedes-Benz, in close collaboration with AMG’s Affalterbach team. “Compared with conventional electric motors, the innovative drive delivers a considerably higher sustained power output as well as higher torque,” AMG stated.
Michael Schiebe, CEO of Mercedes-AMG GmbH, called the GT XX “a whole new dimension of performance.” He added, “We’re bringing groundbreaking technology that redefines high performance. And the best thing is that this car is a true AMG with every fibre of its being.”
The GT XX is supported by an 800-volt architecture and features AMG’s newly developed High Performance Electric Battery (HP.EB), which integrates over 3,000 cylindrical NCMA cells. The battery, with a cell-level energy density of 300 Wh/kg, supports charging at more than 850 kW, allowing theoretical recovery of up to 400 km of range in five minutes, according to provisional specs. The battery cooling system uses dielectric oil to directly manage cell temperatures and improve stability under repeated high loads.
From a design perspective, the GT XX features a fastback silhouette with a drag coefficient of 0.198, active underbody Venturi aerodynamics, and AMG’s AIRPANEL cooling system. The concept debuts a world-first active Aero Wheel system, using Bluetooth-connected mini-generators to adjust blade positions on the fly for optimal brake cooling and aerodynamic balance.
The interior combines performance and sustainability, using materials like LABFIBER Biotech Leather made from recycled GT3 tyres. AMG’s proprietary software interface runs on the new MB.OS system and includes advanced telemetry and dynamic lighting at the rear via a Fluid Light Panel with 700 RGB LEDs.
Markus Schäfer, Chief Technology Officer of Mercedes-Benz Group AG, praised the global collaboration behind the concept, noting contributions from teams in Germany and the UK: “Together, they have developed the CONCEPT AMG GT XX and are providing an insight into pioneering drivetrain technology and the future of performance.”
