Yup, pretty on the mark.
Also WRT snow performance Telsa has a pretty large advantage over any ICE since they can apply different torque amounts to each wheel in near sub 1ms timeframe due to two factors:
1. Lower rotating mass(you only have stator, axle and wheels in the physical drivetrain.
2. FETs respond much faster than an internal combustion engine.
We got a fair bit of snow a while back and even without dedicated winter tires I was incredibly impressed with the snow/ice handling. Much better than our Subaru by a long shot. You can still get yourself into trouble but it was much harder to overcorrect than on our ICE.
- linsomniac 9y agoThis very much represents what I've experienced with it. The traction control in the Audi's I've had would REALLY retard the engine, and then take a really long time to recover from it. So it definitely does respond faster. I also think that having two truly independent motors is vastly superior to one motor and a Torsen center diff sending it front and back. The quattro would use braking of one wheel to send power to the other side on one axle, with a traditional diff. I haven't really figured out what the Tesla does from side to side. But it seems to work great! We didn't get a lot of snow after Dec when I got it, but what I did get to play in it was very impressive.
- vvanders 9y agoYeah, they use an open diff + electronic braking to send wheel to wheel, seems to work pretty well.
