extra power under load to the rear wheels
Lol like there’s enough room back there to add a load.
Comment on Tesla confirms it has given up on its Cybertruck range extender to achieve promised range
_stranger_@lemmy.world 11 months agoI believe the three motor versions is to add extra power under load to the rear wheels.
The motors are essentially in line with the wheels (they have gearing but it’s minimal and internal to the motor housing, not attached like an automatic transmission would be, if that makes sense.)
The “three motor” design is just the single motor design up front and the dual motor design in the back.
I’m not sure if they ever actually released the single motor version though.

Basically they use the same size motor everywhere, and your total torque and power is dependent on how many you’ve got?
_stranger_@lemmy.world 11 months ago
pretty much. I believe all the cars use the same motor except for the plaid versions (or maybe just the S plaid?) that has a different motor that’s designed to hit higher rpm’s

It’s supposed to tow. In theory.

I’ve seen arcade games built tougher than the interior of that POS lol

More power to the rear makes sense because you get more traction at the rear under normal acceleration, not just when carrying a load. It’s pretty typical of electric cars to do this, just like it’s typical to have bigger brakes on the front of all cars, because there’s more traction at the front under braking.
There’s also the issue of torque vectoring. Without a differential, torque vectoring is essential, but under acceleration torque vectoring to the rear wheels is much more effective than to the front wheels, so that’s another reason to split the rear power but not the front.
