Just a few months ago, Mercedes-Benz's YASA unveiled its most powerful electric motor yet. Engineers have refined its prototype to produce over 1,000 horsepower. Mercedes plans to incorporate this achievement into future models.
The newly developed motor delivers 59 kilowatts per kilogram, equivalent to 79 horsepower per kilogram, significantly surpassing Yasa's previous record of 56 hp/kg. The prototype weighs just 12.7 kilograms and produces a peak power of 750 kilowatts (1,006 hp). By comparison, this is comparable to supercar-level power, yet weighs less than a typical e-bike. Even under continuous load, the motor delivers 350-400 kilowatts (469-604 hp).
Importantly, it does not use exotic and expensive materials. Unlike traditional radial systems, axial systems rely on thin disc rotors, delivering greater torque at a lower weight.
YASA CTO and Founder Tim Woolmer called this result "a key validation of the efficiency of next-generation axial electric motors." Mercedes acquired YASA in 2021 and plans to integrate these electric motors into future flagship electric sedans and SUVs.
