- Yasa's electric motor prototype weighs 28.8 lbs and outputs 737.5 hp, setting a power density record.
- Yasa's motor is scalable for mass production, not requiring exotic materials, with potential for 50,000 units/year.
- Koenigsegg's Dark Matter motor produces 800 hp but is heavier, resulting in lower power density (15 w/kg vs. Yasa's 42 w/kg).
- Yasa motors are used in high-performance hybrids from Ferrari and Lamborghini, and Mercedes-Benz's AMG GT XX Concept.
- The article questions the necessity of extreme horsepower in EVs, suggesting lighter, modest motors could drive affordable EV development.
