The Rivian R1S and R1T are refreshed for 2025, adding an 850-hp Tri Motor model and improved batteries, including a new lithium-iron-phosphate Standard pack.All electric motors are now built in-house by Rivian, with the revised Quad Motor model now making 1025 horsepower and 1103 pound-feet of torque.The new second-gen R1S and R1T also receive tweaked chassis, updated lighting elements, and enhanced driver assists—base prices are lower in some cases too.
The R1S and R1T Quads also have higher top speeds of 130 mph thanks to a new set of staggered Michelin Pilot Sport S5 tires. Of course, we'll need to conduct our own tests to verify those claims. What's notable about the new Tri Motor and revised Quad Motor configurations is that the electric motors are now built by Rivian in-house, whereas before the Quad's were built by Bosch. The twin-motor setup was already done in-house.
