It was the Rivian R1T's turn to undergo the InsideEVs 70 mph high range test; the first electric pickup truck we've had the opportunity to do so with.
The R1T has a combined EPA range rating of 314 miles per charge. However, that's with the 21" Road wheels. Rivian also offers 20" All-Terrain and 22" Sport tire & wheel packages, both of which will reduce the driving range.
