We know the CT will be fast. The off-road performance can be demonstrated in shorter test and controlled YouTube releases. The CT could make and appearance just don't race it.

The race costs a lot and the chance of a failure causing bad PR is not worth it. Ask Nikola.

I say no.

Baja is a great, tough test track for any style of vehicle. Takes a lot of confidence, real "money where your mouth is" place.

But Lordstown didn't do so well there, if you recall.

Not Baja, but Moab. Not CT, but Rivian.
Shows the need for *much* beefier suspension due to "instant torque" power over rocks.
(btw trail mater is a great channel to follow for back country vehicle situations)

There's no such thing as bad publicity.

I've been subscribed to TRAILMATER's channel for a while now and love the shows. What did NOT impress me about the Rivian in this episode is how much wheel spin is allowed before sending more power to the non-spinning wheels. With four independent motors, the Rivian should have a "full lockers" mode that replicates its mechanical counterparts.

Cybertruck Gen1 is an F-150+ killer — not a Trophy Truck.

I know dynamic suspension jolts the brain with “winning” vibes. But the reality is that Baja don’t care. Its Baja, its Mexico and gringos can have all the fancy big words, latest technology, go-fast juice and still drag themselves and their GOAT truck home in pieces.

Tesla might re-orient its dynamics 90° once it has more experience with wishbones on all four corners. I’m figuring Gen3 CT at soonest before Tesla builds swing arms at rear. ONLY competition beating Tesla to line honors in Baja could change that.

With four motors there's no "sending more power to the non-spinning wheels". The Rivian has ~800hp total, meaning each wheel has ~200 hp available to make it turn, and that power isn't affected by other wheels spinning. It isn't like the traditional one motor 4X4 ICE vehicle where all the horsepower of the engine can be shunted to one tire that's spinning in the air. A Rivian could have one tire off the ground, spinning at 100 mph (the computer wouldn't allow this to happen probably), but each other tire with traction will still have all ~200 hp of it's capability pushing that tire along. It may seem like a waste not to be able to shunt that power to the two (one?) tires with traction, but is there really any situation where one tire needs more than ~225 ft/lbs of torque? That's more than enough power to overcome the friction of the tire/surface.

Next year Rivian is promising to release a dual motor version. That will benefit from locking differentials. I REALLY hope they don't do a brake application version of traction control. Brakes can steal power in many cases.

It may seem like a waste not to be able to shunt that power to the two (one?) tires with traction, but is there really any situation where one tire needs more than ~500 ft/lbs of torque? That's more than enough power to overcome the friction of the tire/surface.

I understand all that, but I can't quite believe that all four tires could be on sandstone with the truck not moving, and yet only one tire is spinning if the power modulation software is working efficiently. Rivian could easily reduce power to the spinning wheel. Furthermore, I can't believe that the other 3 unmoving tires each had 200 hp applied to them without being able to move the truck. Bottom line, their software needs work.

A broken tie rod isn't likely due to too much torque to the wheels, but rather too much force from the steering rack. Tie rods usually break when the driver tries to turn the steering wheel when the tire is up against something (like a rock) that won't let it rotate on it's vertical axis. It's such a common mistake even amongst experienced rock crawlers that many carry a spare tie rod with them, just in case.

My question for Rivian is: Can your onboard power outlets run a welder?!? 🤔 It'd be kind of nice to haul a welder along when you go 4 wheelin' 😃

Theoretically I can get more torque if I'm not wasting power. But the real problem with the "spinning tire" is from it digging a deeper and deeper hole.

The computer should limit a "spinning" or non-productive wheel.

😬 If it's digging, it's producing forward (or backwards) force.
Yeah... there's a limit to how deep you want to dig, but holding (the equivalent of 1200 rpms ICE) in mud or snow is desirable.
