The Rivian R1T wins on performance with 3.0 s 0-60 versus Yukon's 5.5 s and superior EV features, but the GMC Yukon provides better value for traditional towing needs with 13,400 lb capacity and widespread service. R1T trails on range anxiety and service access per Edmunds and Car and Driver comparisons. Yukon suits gas-dependent buyers while R1T excels for electric off-road enthusiasts.
