HIGHWAY RANGE TEST: RIVIAN R1S DUAL MAX VS MERCEDES G580E VS HUMMER EV

EV Channels Review

This video pits three electric adventure SUVs against each other in a 70 mph highway range test: the Rivian R1S Dual Max, Mercedes G580e (EQG), and Hummer EV. The Rivian R1S, despite its EPA rating of 410 miles, struggled to meet expectations, with the reviewer predicting it wouldn't hit 400 miles on the highway due to optimizations for EPA cycles rather than real-world highway driving. The Mercedes G580e, with an EPA rating of 239 miles, surprisingly outperformed its estimate, with the reviewer anticipating it would exceed 250 miles. The Hummer EV, rated at 313 miles, was expected to be closer to its EPA figure. The test highlights the significant differences in real-world highway efficiency compared to EPA estimates, with the G-Class proving more efficient than the Hummer, and the Rivian falling short of its potential. The G-Class's efficiency was noted as being around 2 miles per kWh, while the Hummer was consistently around 1.6 miles per kWh. The Rivian's efficiency varied, starting around 1.72 miles per kWh and improving to over 3 miles per kWh on the return leg. The Mercedes G580e ultimately ran out of charge first, followed by the Rivian R1S, with the Hummer EV being the last to deplete its battery.
