The first battery-exclusive AMG leverages high-density axial flux motors to mitigate EV weight penalties and push peak power over 1,100 hp.
Mercedes-Benz has launched the AMG GT 4-Door Coupe, the first true AMG powered exclusively by batteries, featuring a powertrain centered on axial flux electric motors. As first reported by Ars Technica, the vehicle utilizes three motors produced by Yasa, a company Mercedes acquired in 2021.
These axial flux motors provide a smaller and lighter powertrain compared to traditional designs. The setup includes one motor in the front measuring 3.5 inches (89 mm) wide and two in the rear with a width of 3.1 inches (79 mm) each. In the AMG GT 63 trim, these motors deliver a nominal output of 711 hp (530 kW) and 1,475 lb-ft (2,000 Nm) of torque, with a peak power output of 1,153 hp (860 kW) available for 63 seconds during "Boost mode." For the AMG GT 55 trim, nominal output is 557 hp (415 kW) with 1,372 lb-ft (1,860 Nm) of torque, while Boost mode allows for a peak output of 805 hp (634 kW) for 55 seconds.
Ars Technica notes that this hardware allows the vehicle to accelerate from zero to 60 mph in approximately 2.3 seconds. The performance is further supported by the AMG.EA sports-car architecture, which manages power delivery alongside active aerodynamics and Active Ride Control suspension. To support these power densities, Mercedes implemented an 800 V system capable of DC fast-charging at up to 600 kW; Ars Technica reported one AMG GT 63 vehicle hitting a peak of 637 kW during a demo, charging from 17 to 80 percent in roughly 10 minutes.
