First of all, I have put over 12,000 miles on my R1T in 5 months and I still love it today. For an all around vehicle nothing beats it.

As shown in our previous 4x4 roller test video, the quad motor could use a transfer case or even some sort of "simulated locker" to really perform excellent in low speed crawl scenarios. Understandably this wasn't designed to be a rock crawler. Handling and traction control is amazing at medium to high speeds in offroad scenarios which is a compromise I am willing to accept. (but still frustrating only because I know it can be better)

In the beginning of the video we go over our tug of war setup (because safety is important) while simultaneously promoting our product. If you want to skip straight to the 3 pulls we did they start around 3:45 mark. ENJOY!!!

EDIT: IMORTANT CONTEXT ADDED
1. With our knowledge from our previous 4x4 roller test I floor the accelerator pedal QUICKLY in pull 2 and 3. Even with "traction control off" I believe the Rivian computers are still limiting wheel speed! Too smart to let us have fun? hahahah.

2. The curb weight of the Ford F350 is 6,769 lbs and it is NOT heavier than the Rivian.

3. The Rivian has a documented axle ratio of 12.6:1. The "ground torque" is quoted to be 14,000 Nm which is 10,325 lb-ft. If you do the math thats about 10% drivetrain loss. (Which is really good)

That was cool. Not really that surprised by the results. That Ford is a beast. It looked like the Ford also had MT tires on it?

I agree, several people looking for a full size spare option for the R1S, this looks like the best swing away one I have seen. You should probably demo it on an R1S for all of those folks.

Supposedly it doesn't fit on the R1S. I think the rear end is rounded off quite a bit more and gets in the way.

That’s a bummer, I’m sure the market for one of these would be larger for the R1S.

Do you plan to make a hitch spare tire carrier for the SUV?

Any chance we can open the lower tailgate too?

EVLANDER tested one for us on an R1S and the Trail Swing fits dimensionally. The issue is there is no access to the back of the R1S hitch to tighten our wedge system for the anti wobble. I have been going back and forth on several variations of designs to solve this issue but I haven't nailed down the design yet.

So for people who don't have time for a 10 minute video - who wins? I'm guessing the Ford?
I know how forums and the internet works... I was even nice enough to put the exact time mark in the original post where the pulls happen so you don't have to watch the 10 minute video ;), but I guess reading also eludes those of us in a time crunch :movember:. This one is for you. A little extra information that was not included in the video

Initially the R1T due to instant torque. Then the F350 took over with more lower end/overall torque.

What I don't understand is with traction control off, why aren't all 4 tires just doing a burnout? Driver perfectly feathering the throttle to the point of no slipping?

Are you developing sliders? Nice work on the spare carrier. Bookmarked.
