  • 28-pound electric motor delivers 1000 horsepower

  • No, less than 2000 cars is not mass market.

    To secure your order for one of the 1,980 examples of Renault 5 Turbo 3E, contact us below. You’ll get a call back very soon to make an appointment to reserve in the retailer.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.

  • I'm looking for benefits over current EV drivetrains. So far, there aren't any.

  • They DO require transmissions! A single speed planetary gear set is still required, same as current EV drives.

    Find me a hub motor datasheet with quoted power and torque below 1000 rpms. The YASA datasheets are all out to 8000 rpms. Useless at wheel speed.

    They're quoting 30 second power numbers and dry weight without a gearbox. They're fishing for dumb money.

  • I agree, they are good for minimally suspended low speed personal transport.

    That car is the definition of a party trick. You proved my point, so thank you.

  • Not even the concept had hub motors.https://www.autoexpress.co.uk/news/volkswagen-id-polohttps://electricarworld.com/volkswagen-polo-makes-a-comeback-as-an-electric-car/https://auto.hindustantimes.com/auto/electric-vehicles/volkswagen-id-polo-gti-breaks-cover-at-iaa-mobility-comes-as-reborn-polo-gti-41757316409552.html

    Limited slip differential? Can't do that with hub motors. https://www.topgear.com.ph/news/car-news/volkswagen-id-polo-prototype-a5100-20250908

    If you have different information about a production car, please share it. The theoretical concept ID.2 R may use hub motors but that is vaporware at this point.

  • They make sense for scooters, bikes, and other low speed or two wheel personal transport. For anything with an actual suspension (designed for a highway) there is just too much competition for space with brakes and suspension linkage. The unsprung weight, exposed high voltage cabling subject to road debris and accidents are problems too. And what to do hub motors really gain you?

  • Two economists are walking in a forest when they come across a pile of shit.

    The first economist says to the other “I’ll pay you $100 to eat that pile of shit.” The second economist takes the $100 and eats the pile of shit.

    They continue walking until they come across a second pile of shit. The second economist turns to the first and says “I’ll pay you $100 to eat that pile of shit.” The first economist takes the $100 and eats a pile of shit.

    Walking a little more, the first economist looks at the second and says, "You know, I gave you $100 to eat shit, then you gave me back the same $100 to eat shit. I can't help but feel like we both just ate shit for nothing."

    "That's not true", responded the second economist. "We increased the GDP by $200!"

  • Hub motors are a party trick. They will never reach mass market in a car.

  • How often do you update software on your servers?

  • Probably every 2 months. When I have a day off work with nothing to do. I have a few VMs that are more fragile than I want to admit and if something breaks I want to have time to tinker instead of just restoring a backup.
