This innovative in-wheel motor system brings several advantages:
- Improved efficiency with approximately 30% less mechanical loss
- Enhanced manoeuvrability with a 10-15% reduced turning radius
- Independent wheel control for superior traction and stability
- Increased interior space due to the elimination of traditional drivetrain components
- 25% more efficient energy regeneration through precise brake control
My wife and I own two EVs and are looking to swap one for another EV. What are you on about?
I am specifically talking about the problems with putting motors in wheels. It’s not a new idea, but manufacturers have hesitated to do it for various reasons. Unsprung weight and increased replacement cost among them.
You can’t imagine an accident where the wheels get hit?
Cars get totalled for less. A bent wheel on a luxury car is the least of my worries.
OK, so your position is that modern cars are so fragile, you won’t be replacing the wheels, anyway. You’ll just be junking the whole car.
Which is true, I guess. It’s not exactly a stellar place to be in general, but OK.
My position is that if someone wants to make this and a buyer wants to buy it, it’s nothing but good news. They know and accept the risk, and the rest of us have better things to do than interfere.
And my position is that people should go into that with an honest appraisal of the up and downsides. Are we supposed to rely on the manufacturer to tell people that?
I’d be surprised anyone would bother reading that fine print.
I don’t understand, what do you envision the disadvantage is over tradition axel wheels? It’s cheaper and easier to repair because you don’t have to fix the entire axel, but just fix one. Also, each of the four motors are cheaper than one combined one, for both sunk costs and upkeep costs. What matters is the consistency between the four motors.
It’s not cheaper to repair when there’s a whole lot of copper and magnets in the wheel. Copper ain’t cheap.
Unsprung weight problems are mostly an issue for those of us who like to run cars on the track, but it’s a consideration.
