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.
