Mercedes-AMG GT XX Debuts As AMG’s First All-Electric Concept
AMG has finally unveiled its own entirely electric vehicle concept, giving a sneak peek at a potential four-door sports vehicle.Introducing the first all-electric concept from Mercedes’ legendary performance division, the Mercedes-AMG GT XX. The four-door GT XX concept serves as a sneak peek at Mercedes-AMG’s upcoming first series model. The main statistics include a maximum speed of nearly 360 kph, a range of over 400 kilometers in just five minutes, and a peak power output of 1,360 horsepower. The first model to be supported by Mercedes’ AMG will be the production variant.The architecture of an EA skateboard. This is a technological demonstration for the most potent AMG to date and the GT 4-Door Coupé’s successor.
According to Mercedes, “the heart of an AMG is always the motor,” therefore let’s start with the GT XX’s engine. Mercedes claims that the three axial flux motors (two on the rear axle and one on the front) underneath the skin are substantially lighter and more compact than traditional e-motors (radial flux motors). Additionally, it is claimed to be three times more energy dense, which enables better continuous power and performance repeatability—two things that high-performance EVs typically lack.

This is the first time axial flux motors have been used in an all-electric vehicle; previously, they have mostly been found in hybrid supercars (such as the Lamborghini Temerario and Ferrari SF90 Stradale).
Together with the front electric motor, the two oil-cooled electric motors at the back generate 1,360 horsepower. They are housed in a single unit with a planetary gearbox and an inverter. The GT XX now has an all-wheel drive setup as a result. The front motor only engages during severe acceleration, energy recovery, or when more traction is required; otherwise, it is rear-wheel driven in most situations.

The GT XX concept’s battery, which draws inspiration from Mercedes’ Formula 1 racing division and the AMG One hypercar, is arguably its most noteworthy technological advancement.The GT XX design makes use of tall, thin cylindrical cells and a 114kWh battery with NMC (nickel/manganese/cobalt) chemistry. According to Mercedes, the tiny distance between the cell’s core and casing allows for a quicker energy discharge and aids in efficient cooling. Additionally, the cells’ shell is made of aluminum rather than steel, which is superior for heat and electrical conductivity.
The fact that the cells are individually packaged in plastic modules with direct cooling is also noteworthy. To guarantee that every cell receives the same amount of cooling, a sophisticated coolant circulates through tubes in the modules. In addition to its 800V construction, the battery features a brand-new battery management system that AMG developed internally. It has the potential to accommodate up to 850kW of DC charging.
