Unsatisfied with kicking off its brand with just one breakthrough vehicle, Rivian launched the R1S sports utility vehicle alongside the R1T pickup truck. The R1S is a seven-passenger AWD high-performance EV that brings some healthy competition to Tesla’s Model X— formerly the only three-row all-electric SUV. While the two vehicles belong to the same segment, their appearances are strikingly different. The R1S’s flat, boxy exterior contrasts with the Model X’s curvy body. The R1S, unlike the Model X, is off road–capable, sharing the R1T’s 14.5-inch ground clearance, 3.5-foot wading depth, and sophisticated torque vectoring enabled by a dedicated electric motor at each wheel. Its 34.8° approach angle, 34.3° departure angle, and 28.9° breakover angle enable durable all-terrain climbing. Both the R1S and the R1T are built using the same electric platform and boast exceptional specs, including 750 horsepower, 829 pound-feet of torque, and a 0-60 mph time of three seconds. Their top trims carry identical 180-kWh battery packs that endow them with a 320+ mile range. The batteries are aligned in single rows on their “skateboard” chassis, achieving a low-center of gravity for superb handling. The R1S doesn’t quite match the R1T’s towing capacity, but manages 7,700 lbs. Inside, the R1S sports light-up accents throughout the cabin and an electric flashlight set in the door trim. Its interior is made of leather and sustainably sourced wood. Although the initial cargo space is tight at 7.1 cubic feet, the third row is removable for increased capacity. Look for the R1S to make major waves in the EV world’s burgeoning off-roader segment.
