Feb 10, 2015 at 7:42 comment added chilljeet I believe the tesla model S uses an open differential. It probably uses some form of traction control strategy to manage traction by individually braking the slipping wheel to lock the differential and controlling the overall output of the motor. Individual motors - torque vectoring? However even torque vectoring can be achieved through the current setup (similar to tcs implementation) , though i don't believe it's currently implemented.

Feb 8, 2015 at 17:28 comment added michaelyoyo The Tesla doesn't have a multispeed gearbox, it only has a single, fixed gear ratio. I'm not sure how it distributes power though. The Electric Mercedes SLS AMG has 4 separate motors directly driving each wheel, which has some benefits for track driving (and I assume off road but it's not an off road car), but it's a lot of extra effort when you don't need it.
Feb 8, 2015 at 17:16 comment added mkeith It is a basic requirement of a modern car to distribute power to the drive wheels separately somehow. The existing mechanical differentials are reliable, and can be locked or unlocked, or have posi-traction, etc.. I think having separate motors for each wheel would open a lot of possibilities, especially for off-road vehicles, but it is a more dramatic departure from the norm. The motors would have to be moved to the sides of the vehicle which could be awkward.
Feb 8, 2015 at 14:49 comment added Roland Mieslinger I'm wondering if the Model S has a multi speed gearbox and clutch at all? Compared to fuel engines, electrical motors are able to produce power/torque over a much wider range, which should eliminate the need for a gearbox (other than single speed).
