Ford's CEO says he definitely didn't pay for that viral video of a stuck Cybertruck needing a rescue on a snowy hill::undefined

Why did the CT fail? Is it only 2WD? Bad power distribution algorithm to wheels? Stranded on belly (low clearance)?

EDIT: Yes possibly bad power distribution, but I don't necessarily trust the source.

He said on Instagram that the Tesla didn't have locking differentials — a mechanism that can help improve traction on difficult terrain— "due to software issues." He also said the tires had not been "aired down" to improve traction.

Iirc it was mostly a stupid driver with improper tires on terrain that didn't quite look as bad as it actually was.

The cybertruck doesn't have differentials at all, so it shouldn't need locking diff's.

The entire point of having differentials is to make sure the power from the engine isn't being misdirected to a wheel with no traction, but the cybertruck has independent motors for each wheel.

The couple of seconds' worth of video I saw told me a few things:

  • the truck had been spinning out for a long time there

  • that situation was going to be tough for most trucks

  • it had terrible traction, possibly a matter of not having all-season or snow-specific tires

  • it appeared to be driving all wheels, can't say whether or not they were distributing traction or slip intelligently

  • couldn't tell if anything was high-centering anywhere but it didn't look it

  • driving in situations like that are why I leave tire chains in my truck

  • the tree sticking out of the back was comical

The cybertruck is a pavement princess

Based on the older video of the CT failing to climb a rocky/dirt hill, I'd say they have a lot of work to do on their power distribution/traction control systems. Thankfully since it's all controlled with electric motors and not a traditional transmission/transfer case/solid axle setup, it should be able to be fixed or mitigated with OTA updates.
