The new electric motor weighs 13 kilograms and is more powerful than a Lamborghini, producing 738 horsepower.

A new chapter in electric motor design is being written - and in the UK. Yasa Motors, a British company owned by Mercedes, has developed a new electric motor that sets new standards in terms of power density, reports Telegraph. Although it is not yet known when production will begin, it is almost certain that Mercedes' future electric models will be among the first to use this revolutionary technology.

Yasa claims that their electric motor weighs just 13.1 kg and produces an incredible 738 horsepower, the kind of power we usually associate with supercars. This easily surpasses the Australian Equipmake HPM-400 engine, which until now was considered the engine with the highest power density - it develops 536 horsepower and weighs a full 40 kg.

The new engine also makes Koenigsegg's Dark Matter electric motor, introduced a few years ago, look like a heavyweight. Dark Matter weighs 39 kg, produces 800 horsepower, and will debut in the Gemera model. But the weight difference suggests a new era in the development of high-performance electric motor systems is coming.

"What we've achieved isn't just a number - it's a demonstration of a production-ready, scalable innovation that pushes the boundaries of electric motor design. And the most exciting thing is?

We're just getting started," said Tim Woolmer, founder and CTO of Yasa. The latest car to use Yasa engines is the Mercedes-AMG GT XX concept, which uses three axial-flux electric motors to produce a total of 1,360 horsepower (1,000 kW). This model will soon enter series production.

Yasa also supplies Lamborghini, including the Revuelto and the latest Temerario, the successor to the Huracan. At Lamborghini, the system uses two axial-flux electric motors on the front axle, each with 150 horsepower (110 kW) and each motor weighing 17.3 kg.

Now, these figures pale in comparison to the power-to-weight ratio of the latest Yasa engine. /Telegraph/
