Two words - hub motors.

Reduce the weight by 75% over current approaches means less unsprung weight. That would be meaningful.
Someone commented that. Isn't unsprung weight weight that is not "sprung" by the suspension? AKA wheels/axles? Wouldn't that make hub motors create more unsprung weight.

For the DIY electric cars, this motor isn't all that special. We need lighter/cheaper batteries.
