> Tesla uses the the tri-motor system from the Models S/X Plaid on one axle of the Semi, which seems both dangerous and needless, given the lack of concern among Semi users for quick acceleration
Jay Leno did an interview with one of the Tesla Truck engineers the other week, I believe he mentioned each axle is geared differently. One specifically for highway speeds and the other one disconnects for optimal efficiency once up to speed.

- toomuchtodo 3y agoThat’s standard for Tesla drivetrains on their cars to avoid transmissions: one axle for low speed, one axle for high speed, blending power to the motors and idling one when the other is primary.
- snek_case 3y agoThere's an extra trick with the semi where one of the axles can disconnect from the motor once it's up to highway speeds.
- code_runner 3y agoI love the assumption here that truck drivers just aren’t interested in better acceleration.
- itsoktocry 3y agoI love the assumption here that everyone all of a sudden cares about acceleration.
