Yasa's 750 kW axial-flux motor hits 59 kW/kg, reshaping EV design

The British company Yasa has set a new unofficial high-water mark for specific power in an electric motor. Its latest axial-flux unit produces 750 kW (1005 hp) while weighing just 12.7 kg. That translates to a power density of 59 kW/kg, roughly 40% higher than the previous record.

For context, this motor is about eight times more powerful than the rear electric motor in a Tesla Model Y Standard and eclipses most production setups. Just as important, in continuous operation it can deliver 350–400 kW.

The design avoids rare materials and is engineered to scale for mass production. The underlying technology already powers cars like the Ferrari 296 GTB and Lamborghini Temerario, and features in the Mercedes-AMG GT XX electric concept.

Light weight and high efficiency make solutions like this especially attractive for upcoming EVs, where trimming mass directly benefits driving range and charge times. Breakthroughs of this kind tend to nudge development away from brute battery capacity and toward smarter packaging and tighter drivetrain integration.
