Introduced as the R1T truck's mechanical twin, the Rivian R1S is the automaker's first SUV and one of the few electric three-rows on the market. The R1S was significantly overhauled last year, with enhancements that included a reworked electrical system, plus larger battery packs and revised aero for improved range. The party continues for 2026, with Tesla's NACS charging port replacing the previous CCS plug. A hands-free driving system also debuts. But the change we're most excited for is in the form of the range-topping quad-motor, which now produces more than 1,000 horsepower.
