Rivian has gone to great lengths to improve its flagship R1S SUV and R1T pickup. There are so many changes that the California-based EV maker is referring to the 2025 models as the second generation, even though you’d be hard-pressed to notice the differences between the old and the new cars, at least at first glance.
One of the biggest novelties with the 2025 R1T and R1S is the exclusive use of Rivian’s own electric motor throughout the drivetrain options, including the quad-motor setup that previously used Bosch-supplied drive units. That change increased the maximum power output by about 200 horsepower in the case of the quad-motor EVs, for a total of 1,025 hp. This leads to a claimed 0-60 miles per hour time of under 2.5 seconds, which is mind-boggling for a big, heavy truck.
