RIVIAN R1S 70 MPH HIGHWAY RANGE TEST

EV Channels Review

This livestream range test of the Rivian R1S focuses on its highway performance at a constant 70 mph. The reviewer notes the vehicle is equipped with the Large Pack battery and 20-inch all-terrain tires, a deviation from the preferred 21-inch road wheels due to scheduling conflicts. The test was conducted in favorable 70-degree weather with minimal wind initially, though headwinds were anticipated. The R1S achieved an indicated range of 311 miles at 100% charge in 'Conserve' mode with climate control off. Real-world efficiency was around 1.88 miles per kWh initially, improving with tailwinds to over 2.76 miles per kWh, but expected to decrease on the return leg. The reviewer highlights the R1S's comfortable ride, even in its lowest suspension setting, though notes it's less refined than the R1T. While acknowledging the R1S's practicality as a seven-seater SUV, the reviewer personally prefers the R1T for its utility and ride quality. The test did not yield a definitive final range number within the livestream, but the initial efficiency figures suggest a real-world range likely falling short of the EPA estimate, especially with all-terrain tires.
