🚨 MERCEDES JUST PUT A MOTOR ONLY 8 CM THICK INTO A CAR THAT CAN HIT 62 MPH IN 2.1 SECONDS.
Instead of conventional radial flux motors, Mercedes is betting big on axial flux technology. In these motors, the electromagnetic force flows parallel to the axle, allowing two magnetic rotors to sandwich a central stator in a flat, disc-like layout.
The result is dramatically smaller and more powerful. The front motor in the new all-electric Mercedes-AMG GT 4-door Coupe is just 9 cm wide. The rear motors are even thinner at roughly 8 cm each. Despite their tiny size, they help launch the heavy performance car from 0-62 mph in just 2.1 seconds, with a top speed of up to 186 mph.
Why this matters:
• Axial flux motors are significantly more power-dense and can be up to 50% lighter than traditional designs
• Their extreme thinness frees up packaging space in the vehicle for better weight distribution, aerodynamics, or interior room
• Mercedes acquired YASA in 2021 and has spent years developing the complex manufacturing processes needed to build them at scale
• The technology is debuting in a high-performance AMG model, showing Mercedes is serious about using it in its most demanding cars
The deeper implication:
While most of the EV conversation focuses on batteries and software, the electric motor itself is undergoing a quiet revolution. Axial flux designs have long been seen as theoretically superior but extremely difficult to manufacture at scale.
By solving the production challenges and putting these motors into a real high-performance car, Mercedes is pushing the entire industry forward. The next generation of electric performance cars may not just have bigger batteries they may have fundamentally better motors.
We’re watching the physical hardware of EVs evolve as dramatically as the software has.
How important do you think motor technology (rather than just battery size) will be for the future of electric performance cars?
