RIVIAN R1S 70-MPH HIGHWAY RANGE TEST (135KWH LARGE PACK QUAD-MOTOR)

EV Channels Review

In this comprehensive highway range test, the Rivian R1S, equipped with the 135kWh Large Pack and Quad-Motor setup on all-terrain tires, achieved a real-world result of 286.8 miles at a constant 70 mph. While this falls slightly short of the EPA estimate of 316 miles, the reviewer notes that the R1S performed comparably to the R1T under similar conditions, even with a slight headwind on the return leg. The vehicle was tested in 'Conserve' mode with the lowest suspension setting for maximum efficiency. Key takeaways include the R1S's comfortable ride and excellent noise insulation, though the lowest suspension setting can compromise bump absorption. The reviewer also touches on wheel and tire choices, recommending 22-inch wheels for a balance of aesthetics and driving dynamics, while acknowledging the 21-inch for maximum range and the 20-inch all-terrains for off-roading. Despite not being the most efficient EV, the R1S delivers a solid range for a large, capable, and powerful SUV.
