Revolutionary Electric Motor Set to Transform Future EVs
In an exhilarating development for the electric vehicle (EV) landscape, YASA, a subsidiary of Mercedes-Benz stationed in the U.K., has introduced a groundbreaking electric motor known as the axial flux motor (AFM). Now in its advanced second iteration, this remarkable motor weighs a mere 12.7 kg (approximately 28 pounds) yet delivers a staggering 750 kW (or over 1,005 horsepower). This yields an unparalleled power density of 59 kW/kg. For context, the motor’s consistent output ranges between 469 and 536 hp. This latest model surpasses YASA’s previous version released in Summer 2025, which weighed slightly more (13.1 kg) and produced 550 kW (738 hp).
What makes YASA’s AFM truly innovative is not just its weight and power but its use of non-exotic materials, proving that cutting-edge technology doesn’t have to come at the cost of accessibility. The prototype is currently undergoing extensive testing to validate its impressive capabilities, attributed to meticulous design, efficient thermal management, and precision engineering.
The Future is Here: The AMG GT XX Concept
To showcase this innovation, YASA and Mercedes have unveiled the AMG GT XX Concept—an exciting four-door coupe equipped with three YASA axial flux motors. This powerful trio enables the vehicle to reach a peak of 1,341 hp and achieve a top speed exceeding 360 km/h (224 mph). Remarkably, the GT XX completed an impressive 24,901 miles in less than eight days, setting 25 long-distance records along the way—demonstrating not just speed but also the durability of the technology.
Understanding Axial Flux Motors
Unlike the conventional radial flux motors found in most electric cars today, which utilize a cylindrical structure, the axial flux motor adopts a flatter design reminiscent of a pancake. This unique configuration allows for an axial flow of magnetic flux, significantly reducing size and weight. YASA reports that their AFM can potentially save up to 1,100 pounds in specially designed vehicles, providing a threefold increase in performance density over leading radial flux motors.
Production of the compact YASA axial flux motor is slated to commence in 2026 at Mercedes’ Marienfelde factory near Berlin. This production process involves about 100 steps—nearly one-third of which are entirely new—leading to over 30 patent applications encompassing advances in artificial intelligence, innovative joining techniques, and cutting-edge laser technologies.
Dive into the Dynamics of the AMG GT XX Concept
The AMG GT XX Concept is not merely a showcase of the YASA AFM; it also serves as a testbed for Mercedes-Benz’s AMG.EA high-performance architecture, integrating various cutting-edge technologies. Its new battery system is the fruit of knowledge gained from developing the AMG One and Formula 1 vehicles. The cylindrical battery cells are designed for superior heat dissipation, encased in aluminum rather than conventional steel to aid temperature regulation.
Furthermore, the AMG GT XX employs a cooling system that uses non-conductive oil to directly manage the temperature of its 3,000+ battery cells. This allows for impressive charging capabilities, enabling the vehicle to gain 248 miles of range in just five minutes. Other innovative features include luminescent exterior paint, a fully variable 4MATIC+ all-wheel drive system, a programmable rear light panel, and built-in speakers in the headlights.
As the automotive world gears up for the electric future, the revolutionary YASA axial flux motor spearheaded by Mercedes-Benz could very well redefine what we think is possible for electric vehicles. The integration of such advanced technologies promises to deliver more efficient, lighter, and ultimately more exhilarating driving experiences in the years to come.
