This Mercedes-Benz Division You've Never Heard of Just Pulled 737 HP Out of a 29-LB EV Motor
Last month, Mercedes-AMG touted the potential of YASA's axial-flux electric motors with its AMG GT XX Concept car, but it seems that EV's powerplant was just the tip of the iceberg. YASA has just claimed an unofficial world record for the highest-power density electric motor 'in its class.' Tim Woolmer, CTO at YASA, made the claim on LinkedIn, saying a new prototype motor it developed produces 550 kilowatts and weighs only 13.1 kilograms. That gives it an astounding power density of 42 kW/kg. The previous unofficial record? Helix, an electric drive system company, made a motor with a 23 kW/kg density. To put that in freedom units, YASA's prototype motor produces just over 737 horsepower and weighs only 28.9 pounds. That's more power than a standard Hellcat engine, in a piece of equipment you can pick up and hold in your hands. How did YASA do it? Details are thin, but Woolmer noted it didn't use any exotic materials, believes the design is mass-producible at 10,000–50,000 units per year and touts 'insane cooling performance.' Continuous power is 'close' to the peak output using only standard cooling fluids, and Woolmer said the peak itself is good for about five seconds. YASA's axial-flux motors are naturally more power dense than the radial flux motors used in EVs today thanks to the inherent design. (If you want to know the long, technical details, check out a deep dive on electric motor design here.) Woolmer says YASA wasn't trying to achieve a world record with its electric motor, saying it 'accidentally' achieved the highest power density. The potential that such a motor has for production vehicles is great. A single electric motor with that much power taking up such little space at a relatively inconsequential weight would be a huge help for packaging, especially for sports cars. Road & Track reached out to YASA to see what other details it would provide about this prototype electric motor, and we'll update this post if we hear back. Theoretically, Mercedes-AMG products would be first up to take advantage of this motor tech, and the upcoming production version of the AMG GT XX is already set to use YASA's axial-flux electric motor tech.

UK-based Yasa claims world record with new 738bhp, 13.1kg motor
Mercedes-Benz-owned Yasa Motors has created what it claims to be the highest-density motor ever built – a 13.1kg unit that produces 738bhp. That equates to 56bhp per kg, which is more than double the industry benchmark of 20bhp per kg. UK-based Yasa calls it an unofficial world record for motor power density – across any application or sector, not just automotive. The electric motor with the highest power-to-weight ratio currently in production is the Equipmake HPM-400, which puts out 54bhp per kg. Weighing 40kg, the Australian-produced unit is used in aerospace and marine vehicles. Yasa's figures were reached during prototype testing last week. What makes the feat most remarkable, says Yasa, is that the unit uses no exotic materials such as cobalt-iron laminations and litz wire. Moreover, it was not created using 3D printing. Tim Woolmer, Yasa CTO and founder, told Autocar: 'This result is a glimpse of what's possible when deep tech, R&D and practical engineering comes together. We've shown that you don't need exotic materials or experimental manufacturing processes to achieve record-breaking performance. "What we've achieved here is not just a number – it's a demonstration of scalable, production-ready innovation that raises the bar for electric motor design. And the most exciting part? We're just getting started.' Once the unit is signed off, production can reach up to 50,000 units a year at its Oxfordshire plant, according to Yasa. In a statement, the firm said: 'While unofficial, this record represents a major milestone - not just for Yasa, but for what's possible at the cutting edge of practical, high-performance electric motor design.' There are no official details about when a production version of the motor could be launched, nor what cars it will power. Yasa currently supplies motors to Lamborghini, Mercedes-AMG and Ferrari, among others. ]]>
