In short, the -theory- is that there may be a difference, but we will not be able to test this theory in the Citicar because in order to make the car move forward, the armature and stator polarities are equal, which (again, in theory) is a torque mode. It can't be changed because our motors are connected directly to the gearbox.

We could flip the differential, but then the speedometer wouldn't work, and the rear brakes wouldn't be as effective.

Good thing about this is that my Citicar will do 0-25 in about six seconds. Bad thing is it takes twice that time to get from zero to 30, and 'tops out' at about 33 (this time of year, with 50f batteries). During the Summer, it goes a few MPH faster because the batteries are warmer.
