Mercedes-AMG has pulled back the curtain on its most radical concept yet—the CONCEPT AMG GT XX. This latest creation culminates the carmaker’s various research programs into high-performance technologies including electric propulsion, extreme aerodynamics, and sustainable materials. With over 1,000 kW (1,360+ hp) of power, the AMG GT XX concept car is a bold glimpse into the future of electrified performance.
“The CONCEPT AMG GT XX is the next milestone in the history of AMG.” said Michael Schiebe, CEO of Mercedes-AMG GmbH.

Axial Flux Motor Architecture
The Mercedes CONCEPT AMG GT XX employs three axial flux electric motors—two on the rear axle and one on the front—leveraging Mercedes-Benz’s acquisition of UK-based YASA. Compared to conventional radial flux motors, axial flux motors provide:
- More Power Density: ~3x higher
- Weight Reduction: 30–40% lighter
- Packaging Efficiency: Occupies 1/3 the volume
The rear unit integrates the motors with planetary gearsets and inverters into a single High Performance Electric Drive Unit (HP.EDU). The front motor engages primarily during acceleration or in low-traction conditions, decoupling during steady-state cruising to minimise losses.
High-Performance Battery (HP.EB)
The HP.EB battery system uses motorsport-inspired thermal management and includes:
- Cell Chemistry: NCMA cathode with silicon-rich anode
- Cooling Method: Direct oil immersion of all 3,000+ cells
- Structural Housing: Laser-welded aluminium shell that contributes to rigidity
Ultra-fast charging capability
- Max Charging Rate: 850 kW (1,000A)
- Mercedes-Benz has partnered with Alpitronic to prototype CCS chargers capable of delivering this output.
Considerations
- Charging performance depends on battery SoC, grid availability, and thermal management.
- Independent validation is required to confirm the claimed 5-minute charge for 400 km (WLTP).
Safety and structural integration
AMG.EA Platform
The Mercedes CONCEPT AMG GT XX uses a composite of aluminium, steel, and advanced materials to meet crash standards. The battery housing integrates:
- Lateral load paths for side-impact protection
- Multi-layer high-voltage insulation monitoring
- Compliance with UNECE R100 and FMVSS 305
Exterior design: Aerodynamics, aggression, and AMG identity
+3 Photos
The exterior of the Mercedes CONCEPT AMG GT XX is sculpted to minimise drag, maximise downforce, and remain instantly recognisable as a performance Mercedes—even in its most experimental form.
Low-slung, wide and purposeful
At 5.2 metres long and just 1.3 metres high, the concept exudes hypercar proportions. Its low-slung silhouette, long bonnet, and short overhangs give it an unmistakable GT stance, while the wide rear end not only enhances stability at speed but also contributes to the car’s bold, muscular look.
Signature lighting with a twist
Up front, Mercedes-AMG integrates a slim headlamp design featuring a light signature inspired by the AMG crest, surrounded by striking DRL patterns. The traditional grille is replaced by a flush black panel, optimised for aerodynamics and flanked by large air channels that help direct airflow across the body.
Active aerodynamics
The entire body has been digitally modelled for aerodynamic efficiency, achieving a drag coefficient of just 0.198 Cd—an extraordinary figure for a high-performance vehicle. This is partly thanks to active aero elements throughout the car, including:
- Active rear wing: Automatically adjusts depending on speed and braking needs
- Rear diffuser with cooling fins: Enhances downforce while managing battery cooling
- Side air curtains: Channel air more cleanly around the wheels and side profile
- Underbody flow optimisation: Paired with the self-ventilating wheels for thermal efficiency and aerodynamic gains
World-first active aero wheels
A true innovation, the patented AMG Aero Wheels are both a design and engineering highlight. Each 21-inch forged aluminium wheel features five movable blades that adjust based on thermal and aerodynamic needs. When closed, they reduce drag to improve EV range; when opened, they facilitate brake cooling and improve downforce.
Each wheel’s micro-generator captures kinetic energy from rotation to power the actuator system, which controls the blades via Bluetooth. This design eliminates external wiring and allows for 200 independent blade movements per charge.
Colour and surface treatment
The concept wears a two-tone matte and gloss black exterior, punctuated by subtle orange accents that echo the biotech silk door handles and seat stitching inside. The overall finish gives it a stealthy yet futuristic appeal, perfectly fitting for a car that bridges raw performance and cutting-edge eco design.
Interior design: Sustainability meets innovation
Inside the CONCEPT AMG GT XX, biotechnology, racing ergonomics, and cutting-edge personalisation converge to create a cockpit that’s both sustainable and track-ready. Every element—visible or hidden—serves a purpose, whether it’s reducing weight, enhancing comfort, or minimising environmental impact.
LABFIBER biotech materials
Two groundbreaking, lab-developed materials make their world debut in the cabin of the AMG GT XX concept:
- LABFIBER Biotech Leather Alternative: Crafted from recycled racing tyres, plant proteins, and biopolymers, this next-gen material replicates the durability and feel of leather while being lighter, fully recyclable, and petroleum-free. It’s used on the seat pads and central console.
- LABFIBER Biotech Silk Alternative: Grown from engineered bacteria, this orange-highlighted material lines high-contact areas such as the door handles and trim. Strong, breathable, and biodegradable, it brings both luxury and circularity to the fore.
3D-printed racing seats with ergonomic precision
Inspired by endurance racing, the fixed carbon-fibre bucket seats are fitted with removable, 3D-printed seat pads, custom-tailored using full-body driver scans. The result: a sculpted fit, enhanced breathability, and modular inserts that can be replaced individually, offering comfort without compromise.
Signature AMG performance touches include:
- Six-point harnesses
- Low-slung seating position
- High beltline
These elements reinforce the GT XX’s motorsport roots while remaining daily drivable, thanks to the cushioning and thermal comfort of LABFIBER materials.
Exposed structure and driver-focused layout
The cabin design strips away the unnecessary, exposing the carbon-fibre monocoque and brushed aluminium braces as intentional design features. Orange accent lines trace the car’s high-voltage electrical pathway, underlining its electrified performance DNA.
A driver-centric layout keeps displays and controls within optimal reach:
- Tilted dual digital screens reduce eye movement
- A floating, slim centre console eliminates visual bulk
- Ambient lighting adjusts to drive modes—from crisp white in Comfort to glowing red in Track
Steering and interaction
The AMG ONE-inspired rectangular steering wheel integrates tactile controls and real-time feedback systems, including:
- Drive mode selectors with embedded LED rings
- Recuperation paddles for adjusting energy regen levels
- LED performance strip displaying acceleration and power flow in real-time
Is this the future of AMG?
The Mercedes CONCEPT AMG GT XX isn’t just here to look cool (though it does); it’s a peek into the future of high-performance driving. It shows us where AMG is headed, blending insane speed with smart sustainability and next-level tech.
