UK-based YASA has just built a tiny electric motor that makes Tesla motors look like slackers, and this invention could potentially reshape the future of EVs
They might work in the rear if used instead of rear brakes. Rears do far less work anyway and brakes are heavy. Powerful electric motors can do a lot of regen, similarly assisting the front brakes.
I’ve had near 8 kilogram rear brake disks on a diesel wagon, not even a performance car that would require huge brakes, current car is 5. Calipers weigh a bunch too. Pads themselves are light, but still add to the whole setup.

Sounds very limited market.
Those are golf cart and scooter motors, not suitable for highways
BMW currently uses brushed motors in their EVs so I’m not looking to them for any advice. Maybe BMW wants their traditional central layout CM450 tech. But! DeepDrive is the first hub motor I’ve seen that did not need gearing, so that is actually cool. I think they’ll be relegated to rear wheels due to scrub radius limitations but that could be ok.
Hub motors are a party trick. They will never reach mass market in a car.
They work well on bikes. I could appreciate 1000bhp hub on my 12kg touring bike. 🤭
I agree, they are good for minimally suspended low speed personal transport.

Renault 5 RS Turbo has hub motors, Nostradamus.
That car is the definition of a party trick. You proved my point, so thank you.
Right, because 2000 of something is not mass production.
And here is a source in China definitely not making >20 hub motors for cars, scooters, etc.
And BMW did not invest $30M in DeepDrive, hub motor supplier.
You should tell these people they are all stupid.
No, less than 2000 cars is not mass market.

That’s because its a limited run show car. Its not meant to be practical.
