Neuer EV-Motor leistet 1.000 PS pro Rad in ultrakleiner Form | Der neue In-Wheel-Antriebsstrang könnte bei zukünftigen Elektrofahrzeugen bis zu 1.102 Pfund einsparen, indem die Hinterradbremsen und Antriebswellen entfernt werden.

>Oxfordshire-based electric motor manufacturer YASA has unveiled a prototype in-wheel powertrain that could redefine electric vehicles.
>The company revealed on December 3 that its compact motor achieved an unofficial world record for power density, delivering more than 1,000 horsepower (hp) per wheel. This breakthrough could reshape EV design, performance, and efficiency.
>At the heart of the system is a 28-pound (12.7-kilogram) electric motor producing 750 kilowatts (1005 hp) of peak power. With a power density of 59 kilowatts (26.7 hp per pound) per kilogram, it far exceeds current industry standards.
>Continuous output ranges from 350 to 400 kilowatts (469 to 536 hp), making it suitable for both high-performance and long-duration driving.
>“In-wheel motors are the major challenge and opportunity for EVs, but until now, technology has been too heavy, limited in torque and not powerful enough,” said Tim Woolmer, founder and chief technology officer. The motor is light enough to fit inside wheels while remaining “mass-neutral,” meaning it does not add net weight to the vehicle.

Anything from interestingengineering is clickbait garbage. It’s use here should be limited, if not outright banned.
It makes Popular Scince look like the NYT.
These have been around for ages. Of course….. micro-cars will never be popular in the US… perhaps in other markets.
