Striving for extraordinary speed, Mercedes-Benz aims to achieve a top speed of 224 miles per hour with its new GT.
Mercedes-Benz has taken the automotive world by storm with the unveiling of its latest concept car, the AMG GT XX. This cutting-edge electric super-saloon showcases a myriad of advanced technological features, setting a new standard for high-performance electric vehicles.
At the heart of the AMG GT XX lies a groundbreaking powertrain, utilising a tri-motor setup with axial flux motors. These innovative motors, about the size of a pizza box, are two-thirds lighter and take up just one-third of the space of conventional motors. With three times the power density, they deliver an astonishing total output of over 1,360 horsepower and more than 1,000 kW. One motor powers the front axle, while two independently inverter-controlled motors power the rear axle, enabling a fully variable AMG Performance 4MATIC+ all-wheel-drive configuration. This allows the car to operate mainly as rear-wheel drive under normal conditions, with the front motor activating for maximum performance.
The AMG GT XX is powered by an all-new 114 kWh lithium-ion battery integrated into the car’s structure using a skateboard layout. The battery incorporates over 3,000 smaller, thinner aluminium cells, each with direct liquid cooling modules and a non-conductive oil coolant for enhanced heat dissipation. The battery system also features passive cooling through underbody plates and an active air control system managing hidden intake vents to maintain optimal temperatures during intense use. The battery operates at a high voltage of over 800 V, which reduces weight through lighter wiring.
The AMG GT XX supports ultra-fast charging, capable of adding approximately 400 km (about 248 miles) of range in just 5 minutes. This is enabled by an average charging power of over 850 kW, delivered through a newly developed prototype CCS charging station co-developed with Alpitronic. The car can handle charging currents of about 1,000 amps across a wide state of charge (SoC) range without compromising battery life.
Performance-wise, the concept targets a top speed exceeding 224 mph and can accelerate from 0-62 mph in less than 3 seconds, making it a direct competitor to other high-performance EVs like the Porsche Taycan Turbo GT.
Innovations abound in the AMG GT XX, with cooling innovations beyond the battery. For instance, 21-inch wheels with blades that automatically open to cool the brakes during heavy use and close for aerodynamic efficiency. The car also offers a unique acoustic experience with a bespoke soundscape.
The exterior speakers are fitted to the front headlights, saving space, reducing weight, and enabling new sound variants. The rear light panel has more than 700 freely programmable RGB LEDs, allowing various content to be displayed. Visible body structures and interior components are inspired by high-voltage cables, creating a close connection to motorsport.
The interior of the AMG GT XX is less fussy, immersed in black, and features two large LCD displays. Mercedes has plans to release a production version of the AMG GT XX in 2026, with less extreme (and expensive) versions expected to follow, similar to the Porsche Taycan. The high-performance battery was developed in conjunction with the AMG Formula 1 team, and the new battery cell design uses cylindrical cells that are unusually tall and slim.
The active Aero Wheel can actively open blades to pump cooling air through the wheel to the brake and back out again. The actuator of the active Aero Wheel generates its own power and communicates wirelessly with the control unit in the vehicle via Bluetooth. The CONCEPT AMG GT XX features an active Aero Wheel, equipped with five movable elements that can improve range and reduce energy consumption.
The high-voltage battery of the AMG GT XX benefits from the experience of the AMG ONE supercar and Formula 1. The Mercedes-Benz Charging Network will expand with next-generation high-performance charging stations. The AMG GT XX is a testament to Mercedes' commitment to pushing the boundaries of electric vehicle technology and performance.
The AMG GT XX, a high-performance electric vehicle, showcases innovative technology and elevates the standards in the automotive world. In sports, the concept car's unique active Aero Wheel improves range and reduces energy consumption, exemplifying Mercedes' dedication to advancements in technology and performance.
