I am no expert at this but I think the Rivian should perform comparably. The Rivian can do 908 lb-ft of torque. Like you say, that's divided up amongst the 4 wheels, so that's 227 lb-ft per wheel. The Jeep can do 260 lb-ft total. The Rivian weighs ~7200 lbs and the Jeep weighs ~5300 lbs. So, with only one wheel of traction you're right. If you can transfer all of that torque on the jeep with less than ~14% loss (which, I dunno, might be reasonable) then the Jeep has more "oomph". With two wheels, the Jeep is still figuring out how to distribute 260 lb-ft and the Rivian has 454. It's not close at that point.
