>this can be a downside for crawling like this because it has no way to send torque from one side to the other I'm pretty sure that there'll eventually be some sort of LSD/locking programming for electric motors. Take the existing F-150 Tremor for example. It comes with a locking rear diff and a Torsen diff in the front axle. If you have a quad motor vehicle, someone could easily write a "locking rear diff" mode that…

It's not about turning at the same pace, the side that has no traction cannot send its torque to the side that does without a mechanical connection. Each wheel is limited to the maximum torque of a single motor vs torque being sent to all wheels in a traditional single ICE engine with transfer case and lockers. You can see a quad motor Rivian performing worse than the new dual motor due this issue, the dual motor can…

You just need motors large enough to break traction. After that, it's irrelevant. Doesn't seem impossible to me.

Honestly both are abysmal. Even the F-150 is slipping like crazy in areas where it shouldn't matter. Locking differentials are really required for this sort of thing - or a four wheel motor setup where a motor is dedicated to each wheel and can apply power equally. Afaik none of the EV trucks have a mechanical locker or even a limited slip?

This might be as easy as a software update for both.

Reducing tire pressures and better/correct tires is also important - but lockers are can make up for that and even the best tires will fail if one wheel is slipping and taking all the torque.

No one is gonna be doing this sort of thing with an EV though. There is no charging infrastructure out in the boonies.

You don't think people have access to electricity in these places...?

To my untrained (WRT off-roading) eye, I didn't see that much difference between the two. I also wonder how much difference there would be due to driver skill. And as mentioned in TFA, Ford has been making trucks a lot longer than Tesla.

Hm? Its pretty massive to me. The Tesla has like no suspension travel. The suspension is barely compressing, and you can see the body bounce over the terrain as the wheels lift or almost lift. If you covered the top of the truck from view, I'd say it looks like a cheap crossover. And the base F-150 is not really a long travel truck, its just... you know, sprung like a truck. A little side by side UTV could run over t…

Lack of suspension travel under compression is a common issue off-road for air suspension vehicles like the Grand Cherokee and to a lesser extent Range Rovers. Maybe same for the Cybertruck.

I'm with you, both trucks struggled a bit but made it to the top. Is this kind of driving an important use case though? I would think it would be more impressive to compare how these trucks handle towing trailers.

All trucks struggle to make it up that obstacle - the concrete is slick with sand and the lumps make it hard to get traction. There's plenty of videos of fully built Wranglers struggling more than the Cybertruck.

I don't see concrete in that video.

It looks like an OTA (aka Recall) update will fix the traction on the Cybertruck.

Without a mechanical locking mechanism at each axle you’re gonna suffer here. Pseudo “locking” can sometimes work with brakes being applied to the slipping wheel but off road that kinda goes out the window.

Yea, that’s often the only utility they have. No water, sewer, internet.

There are vast parts of the country where your cell phone won’t even work. Good luck finding a charging station.

Guess ya can bring your dongle and hope to find a wall plug somewhere but I’d imagine it would take quite a long time to charge.

Off roaders carry extra fuel. Or worst case your buddy who is out with you will circle back to get fuel and come save you. Can’t really do that with an EV.

If no power, how would you have a gas station? You can always drop solar and batteries for a charging station. StarLink for remote telemetry and billing.

Yes, this is a tire test. My Tacoma would skid (scary) on Seattle's steep, wet streets, until I got Michelins. Huge difference and not because of the truck.

Can I ask which tire brand you had before, the ones that were skidding?

It was some weird Chinese brand that the previous owner installed. Had mediocre reviews.
