Let me be clear: I am speaking about the rear wheel drive model.
After I've asked https://mechanics.stackexchange.com/questions/15342/number-of-motors-rwd-tesla , it seems Tesla's rear axle has only one motor.
Searching the Internet, it could not be clear for me if there is a mechanical differential at the center or if it the distribution of different speeds per wheel is done by software, as the info I find on it, seems all based on suppositions.
Now, if instead of using one motor, it used two smaller ones, one for left wheel and another for the right wheel. With the motor outputs not spinning on the axle center, but in the left an right extremes. And the differential made by electronic control.
I see some disadvantages on this approach: need for two separate gearboxes/clutches and need electronics to control two motors separately.
But are there advantages?
