Yasa, a UK-based engineering firm under Mercedes-Benz, has created a breakthrough prototype electric motor weighing just 28.8 lb and generating 737.5 hp - setting a new benchmark for power density at roughly 42 W/kg. While Koenigsegg's Dark Matter motor delivers 800 hp, it is significantly heavier. Yasa's design avoids exotic materials, enabling scalable production of up to 50,000 units annually.
