> 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.
That’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.
