In an era where electric mobility is rapidly redefining the automotive landscape, Mercedes-AMG has delivered a masterstroke of innovation, design, and engineering with the CONCEPT AMG GT XX.

Unveiled in Affalterbach on June 25, 2025, this avant-garde four-door coupé is not merely a concept; it is a manifesto of the brand’s high-performance electric future.

Combining ground-breaking axial flux motor technology, a Formula 1-inspired battery system, and an aerodynamic design rooted in motorsport, the CONCEPT AMG GT XX is the most radical expression yet of AMG’s electrified ambitions.

A New Benchmark in Electric Propulsion

At the heart of the CONCEPT AMG GT XX lies a trio of revolutionary axial flux motors, delivering a staggering peak output of over 1,000 kW (>1,360 hp).

Developed from the ground up by AMG, these motors are packaged into two High Performance Electric Drive Units (HP.EDUs), ensuring not only superior power density but also lightweight efficiency.

The front motor acts as a booster unit, decoupled during steady cruising to maximise range and minimise drag losses via an intelligent Disconnect Unit (DCU).

Each motor is oil-cooled, with water-cooled silicon carbide inverters enabling high-temperature tolerance and conductivity. The rear HP.EDU even integrates hydraulic pumps and control units within a single compact casing.

Formula 1 DNA: The High Performance Electric Battery

The CONCEPT AMG GT XX features a proprietary 800V High Performance Electric Battery (HP.EB) developed in collaboration with Mercedes-AMG High Performance Powertrains in Brixworth, UK.

Drawing on expertise from the AMG ONE and Formula 1®, the battery employs tall, slim cylindrical NCMA cells, encased in laser-welded aluminium housings for optimal thermal and electrical conductivity.

With direct liquid cooling and full-tab technology, the HP.EB offers energy density of 300 Wh/kg (740 Wh/l), ensuring rapid heat dissipation and sustained peak performance—even under high loads.

The result is ultra-fast charging, reduced cable weight, minimal loss, and near-instantaneous return to full power after stops.

Intelligent Aerodynamics and Futuristic Design

A masterclass in aerodynamics, the CONCEPT AMG GT XX flaunts a rebellious fastback silhouette, with a sharply raked windscreen, no rear glass, and an aerodynamic underbody that creates a Venturi effect—optimising downforce without needing a large rear spoiler.

Despite high-performance tyres, the car boasts a record-low drag coefficient of 0.198. Details like the 21-inch forged aluminium wheels with active aerodynamic blades, MBUX Fluid Light Paint, and embedded speakers in the headlights enhance both form and function.

At 300 km/h, aerodynamic efficiency becomes paramount—AMG achieves it with elegance and restraint.

Minimalist Interior with Maximal Purpose

The interior combines exposed technology with motorsport cues. Carbon-fibre bucket seats are integrated into the rear bulkhead, omitting headliners for weight savings and visual drama.

Lightweight pipes and orange closing loops add to the purist ethos, while recycled checker-patterned flooring and 3D ergonomic seat pads reflect both sustainability and performance.

Notably, AMG introduces LABFIBER materials—biotechnology-based alternatives to leather and silk—reinforcing its commitment to future-forward luxury.

The Bottom Line

The cockpit runs on MB.OS, Mercedes-Benz’s proprietary chip-to-cloud operating system. A custom user interface designed in Sindelfingen showcases the powertrain’s workings through animations of the electric motors and battery.

A rear Fluid Light Panel communicates information such as charge status or a digital AMG logo to the outside world.
