Good and valid question. There is no mandate that states each wheel must be powered. One could opt for FWD, RWD, or AWD depending on budget and performance goals. Each motor is also smaller and easier to manufacture. Add in the savings from not needing a tranny and other mechanicals, and there should be a net savings. Even if it only breaks even, its worth it for the performance and efficiency gains.

@EletrikRidesAgain Wouldn't it cost more because your buying/creating 4 separate motors instead of just one main electric motor?

[EletrikRidesAgain]

@EletrikRidesAgain Furthermore, hub motors result in INCREASED efficiency due to the deletion of transmission, drive shafts (all friction), mounts, and other components normally used with remote mounted drive trains. Hub motors incorporate normal braking and regen all inside the wheel, leaving the entire rest of the vehicle for occupants, batteries, and range extenders.

Eventually designers will see these truths, and all EV's will have hub motors standard. If not, I'll wind my own!

@ekuwa69 That's not true. They would not cost more if they were mass produced on the same scale as non hub motors, and they are just as efficient as any other 3 phase AC induction motor. I do not know where you heard/read/saw otherwise, but I researched 2 sources - Protean Electric and SIM drive. Both very powerful and efficient. And they could be competitive if mass produced.

So I disagree, it is unfortunate.

overly complex again, should have stuck with their in hub motor;

my friend works in a dealership, he swears manufacturers overly complicate their cars to then sell more parts (often making more money on parts than the initial sale)

@ekuwa69 Wheel motors "less efficient"?

A Wheel motor powered car called SIM-LEI recently tested on the Japanese JC-08 cycle recorded electrical power consumption of 77Wh/km. A Nissan leaf (which is very similar to the Volvo C30) uses 173Wh/km.

This means a wheel motor powered vehicle can travel over TWICE the distance on a given battery pack capacity.

@EletrikRidesAgain That's not unfortunate. Those motors cost more and are less efficient.

[EletrikRidesAgain]

@EletrikRidesAgain .....but unfortunately it looks like they abandoned the in wheel hub motors.

Can't wait to be able to purchase this car.
