SiC has higher electron mobility than Si so it makes for better (lower loss to heat) devices for switching power. Tesla uses an AC motor so you need a switching power supply to convert the DC battery to AC power. That is done best with a switching transistor (probably a power MOSFET but I'm decades out of the industry so the terms may be different.)

Tesla said they were eliminating 75% of their SiC from their cars... my thought is they might have a DC motor under development as an easy way to achieve this, especially since DC motors are more efficient than AC.

I'll answer follow-up questions and post more info here Message 34210394
