You’ve heard of AMG, but have you met YASA? No, it’s not the latest yoga trend—it’s the electric motor company quietly redefining EV performance under the Mercedes-Benz umbrella. And while they’ve kept a low profile, their latest announcement is anything but quiet.
YASA’s new axial-flux motor prototype just dropped with specs that sound like they belong in a sci-fi movie: 737 horsepower. 28.9 pounds. That’s 42 kW of power per kilogram, a figure that basically smokes every current electric motor on the market—including those used in aerospace. (Road & Track)
If you’re wondering whether that number is a typo—it’s not. To put it in perspective, the entire drivetrain of a typical EV often weighs several hundred pounds. YASA just packed the heart of a hypercar into a box the size of a throw pillow. And they didn’t even have to dip into exotic rare earth materials or alien tech—this is mass-producible engineering at its finest.
So what makes this such a game-changer? Traditional EV motors—typically radial-flux designs—are heavier, less efficient, and harder to cool. YASA’s axial-flux design changes the equation. It’s more compact, delivers higher torque, and cools more efficiently—meaning less waste and way more zoom.
And it’s not just for bragging rights. These innovations open the door for:
Plus, lighter drive systems mean EVs can serve more sectors—from performance cars to compact SUVs to aircraft. (Yes, really.)
Mercedes acquired YASA back in 2021, and it’s becoming clear why. With a new factory in Oxford now online, YASA plans to roll out 25,000 of these motors annually—and that’s just for starters. (New Atlas)
And it’s not just internal use. Word is, performance titans like Ferrari, Lamborghini, and AMG are lining up to get their hands on this tech. The days of EVs being dismissed as “golf carts with iPads” may soon be over.
Because motors like this don’t just mean faster EVs—they mean better ones. More efficient. More affordable. More mainstream.
We’re talking EVs that can finally shake the “compromise” label.
This kind of tech has ripple effects. Smaller motors mean more cabin space. Lighter cars mean less strain on tires and brakes. And more efficient powertrains mean fewer emissions and less grid pressure per mile. It’s the kind of win-win innovation the whole industry (and planet) needs.
Bottom line: This little motor that could might just be the engine behind the next EV boom. And it’s rolling out now—not ten years from now.
