minus-squareIlovethebomb@lemm.eelinkfedilinkEnglisharrow-up5·edit-21 day agoIsn’t that exactly the same idea though? The motor is now on the chassis, but the reduction gear is still a lot of weight. Race cars have gone as far as having inboard brakes to reduce unsprung mass, moving the gearing out to the wheel is silly.

Because a traditional CV axle certainly isn’t 88 pounds. Race cars have gone as far as having inboard brakes to reduce unsprung mass The uniwheel sort of did too, given regenerative braking.
