You can't move past an issue that's the root cause of the problem. Until Rivian changes the behavior of it's quad motor design, then it will never be comparable to today's other "offroad capable" vehicles. That's my whole point.Of course, an open diff would not help Kyle in his video and lockers would help. That was never in doubt. I think everyone’s frustration with your posts stem from the fact that we moved on from that issue 10 pages ago.
But FWIW, later on (maybe further up the hill) I recall Kyle mentions that the stationary wheels were actually being driven with max available torque but were still unable to pull the vehicle up and over the obstacle. So his Rivian was not exactly acting like it had an Open diff, but rather like a LSD with insufficient torque. I have no means of checking if that is the case, but that was the calculation that an earlier poster was trying to confirm.
But in any case, most of us are more concerned with the challenges of replicating an open diff in certain low-mu scenarios.
The other issue you mentioned did indeed seem like there was no torque available....but we know that isn't the case with these high-torque electric motors. What I suspect is happening is that the vehicle is intentionally limiting torque to the motors for whatever reason. It might be to keep the motors from overheating, who knows? I'll tell you this---I did read an article recently that Rivian is building a gearbox to enable torque multiplication through gearing instead of relying on the motors alone. Did anyone catch that article? Very interesting....
