2025 Rivian R1S

The R1S looks as it did before, but its appearance belies several updates. There's a new trim level, Ascend, that starts with a three-motor configuration — two motors on the rear axle, one up front — and a few extras compared to the Adventure base trim. Later in 2025, an updated quad-motor model joins the lineup, generating more than 1,000 horsepower. Behind the scenes are a host of smaller changes: a revised electrical system, motors now manufactured in-house, and increased range. New suspension hardware promises a smoother ride than before, and a hands-free driving system incorporates more than a dozen cameras and sensors to help the Rivian adapt to surrounding traffic, not only the car ahead. Apple CarPlay is still absent, but the updated infotainment system integrates Apple Music's streaming service into an in-dash app.

The R1S' unique skill set gives it a distinct niche among today's dozen or so electric SUVs, and the even smaller field of three-row SUVs. It can generate the same neck-snapping speed as the Tesla Model X, but it offers more room and a nicer interior. The Kia EV9 is one of the best new entrants, a big, roomy SUV with decent range, but can't outdistance the R1S. The Mercedes-Benz EQS delivers Benz's typically aristocratic — and now futuristic — touches at typically high-altitude Benz prices. None, though, can yet match the R1S' Jeep-like off-road ability.
