Forget everything you thought you knew about electric motors for cars YASA’s latest axial flux wonder changes the game completely. Their new prototype tips the scales at a featherweight 12.7 kg (28 pounds) but slams out a peak of 750 kW, or over 1,000 horsepower. That’s a staggering 59 kW per kilogram... a power density record that blows away anything running in a road-going EV today.
The demo unit is already howling away on dynos. The secret is YASA’s axial flux “disc” design, allowing more compact packaging and a higher ratio of power to weight than conventional radial motors. That means if you swapped today’s big, heavy EV drive units for YASA’s new motor, you could save hundreds of pounds or pump far more power into much less space.
Importantly, the continuous power rating is a meaty 350-400 kW (roughly 470-540 hp). The breakthrough was achieved without resorting to exotic materials just clever engineering, advanced cooling, and a hyper-efficient magnetic layout.
While you won’t see YASA’s prototype in dealer showrooms tomorrow, the motor is designed for real production. As battery tech plateaus, lighter, denser, and more cost-effective electric motors could become the new arms race for the hypercar world and, eventually, everything else on the road.
