Mercedes-AMG GT XX Concept: 1360 HP, 850 kW Charging, and Next-Gen Battery Tech
Mercedes-AMG has taken the electric performance game to a new level with the reveal of its latest concept — the AMG GT XX. A high-tech four-door coupe built on the all-new AMG.EA platform, this prototype serves not only as a showcase for the brand’s latest innovations in EV performance, design, and aerodynamics, but also as a preview of a future production hyper-EV that could arrive as early as late 2025.
Powertrain: Compact Motors, Massive Output
At the heart of the GT XX concept lies a tri-motor electric setup developed by Yasa, a UK-based subsidiary of Mercedes-Benz. These advanced electric motors use silicon carbide components, are two-thirds lighter, and three times more compact than conventional alternatives. The configuration includes:
Two rear motors integrated with planetary gearsets and inverters, supported by a precision torque-vectoring system.
One front motor, activated only when extra traction or performance is needed.
Combined output exceeds 1360 horsepower, with a top speed of 360 km/h (224 mph).
While Mercedes-AMG hasn’t disclosed acceleration figures, the numbers suggest performance on par with elite hypercars.
Next-Generation Battery: Fast, Dense, Intelligent
Mercedes-AMG has also developed an all-new battery system based on nickel-cobalt-manganese-aluminum (NCMA)chemistry:
Energy density of 300 Wh/kg — a significant leap from previous EVs.
Over 3,000 vertical, slim-form cells, housed in aluminum casings.
Advanced thermal management using non-conductive oil cooling, with each cell individually cooled and managed by adaptive software.
Charging speed up to 850 kW, enabling 400 km of range to be recharged in just five minutes — rivaling traditional fuel stops.
Mercedes has already developed prototype charging stations capable of handling this output.
Design and Aerodynamics: Past Meets Future
Inspired by legendary machines like the C111 prototypes and the Silver Arrows, the GT XX blends retro heritage with bleeding-edge style. Key features include:
Coefficient of drag (Cd) of 0.198, nearly matching the benchmark EQXX.
No rear glass, multiple air intakes, and active aerodynamics integrated into 21-inch forged wheels.
Wheel blades that open or close based on driving conditions — powered by tiny motors with built-in generators, activated via Bluetooth, and entirely independent from the main battery.
Electroluminescent paint: parts of the body light up or display charge status.
Rear LED panel with 700 LEDs, capable of displaying messages and icons.
External speakers embedded in the headlights, likely for enhanced pedestrian interaction or sound simulation.
Interior: Minimalist, Bespoke, and Lightweight
Despite its size (over 5.2 meters long), the interior is strictly a two-seater. Features include:
Carbon fiber bucket seats mounted directly to the car’s structure, with 3D-printed custom cushions.
Bio-leather upholstery, partly made from recycled racing tires.
AMG Formula 1-inspired steering yoke, dual digital displays (10.25" + 14") with a bespoke AMG UI.
Bare metal dash and roof, evoking a motorsport aesthetic.
Orange high-voltage-style tubing running along the center tunnel.
Door pulls replaced with bright orange racing harness-style straps.
What’s Next for AMG Electric Performance
While the GT XX is technically a concept, production hints are strong. AMG plans to begin manufacturing its next-generation Yasa motors in 2026, and a series-production EV based on the GT XX platform is expected to debut by late 2025.
Meanwhile, Mercedes-Benz is gearing up for the September debut of a fully electric GLC alternative, also built on next-gen EV architecture — a signal that AMG’s electric revolution is just getting started.
