Engineers at YASA, a Mercedes-Benz subsidiary, have developed a unique electric motor with a record-breaking power density of 59 kW/kg. Weighing only 12.7 kg, the motor is capable of producing 750 kW — over 1000 hp. This is 40% higher than the previous prototype (42 kW/kg, 550 kW at 13.1 kg).
The new motor is not just an experiment: it is already undergoing testing at YASA's Oxford center. The design does not require rare materials, and the record-breaking characteristics were achieved through precise engineering and layout. At a peak power of 750 kW, the engine is capable of providing stable operation in the range of 350–400 kW, which corresponds to 475–543 hp.
The development is supported by the British Advanced Propulsion Centre. YASA believes that this technology will form the basis for the next generation of high-performance Mercedes-Benz electric vehicles.
