More mass inside the wheel increases unsprung weight and worsens some ride/suspension characteristics of a vehicle-

that being said the tradeoff might not be too bad in this case.

It’s just reduction gears, not the motor, so hopefully it can be made light enough. Shame that their promo didn’t say a word about the mass.

Quad-motor all-wheel torque vectoring sounds awesome tho.

My semi-educated guess is the heavier weight of the vehicle means the wheels can bear a bit more weight.
