The first and second generations of the Rivian R1S and R1T may look similar at first glance, but there are actually numerous changes under the skin that make the newer models a significant improvement. Rivian now makes its own drive units in-house, replacing the Bosch drive units used in the previous generation. This change allows for the introduction of tri-motor and quad-motor R1 vehicles with significantly more power. The quad-motor version now boasts 1,025 horsepower and 1,198 lb-ft of torque, resulting in an acceleration time of under 2.5 seconds from 0 to 60 mph. The new tri-motor model offers 850 hp and a 2.9-second sprint time.
In addition to the new motors, batteries, and mechanical improvements, the second-generation R1S and R1T models feature an LFP battery pack for the dual-motor R1, along with the addition of a heat pump. This configuration gives the vehicles an EPA-estimated range of 270 miles on a single charge. Real-world testing showed a highway range of 241 miles for the R1S dual-motor model. The updated models also include minor changes such as an emergency function that uses the rear light bar to direct traffic around the vehicle in low-visibility conditions.
Upon closer inspection, there are subtle differences between the first and second generation models, including changes to the front and rear light bars. The second-generation R1 features a more distinct front light bar with added depth, while the rear light bar now includes an emergency function for directing traffic. Other differences noted in the comparison video include variations in door handles, door-opening mechanisms, plastic materials used in the door card, number of cameras on side mirrors, charging port design, interior design, and driving modes.
Overall, the second-generation Rivian R1S and R1T models offer significant improvements over their predecessors, with higher power outputs, enhanced battery technology, and additional features for increased functionality and safety. The changes under the skin, such as the in-house production of drive units and the adoption of an LFP battery pack, contribute to the vehicles’ improved performance and range. While maintaining a similar exterior appearance, the updated models showcase Rivian’s commitment to innovation and continuous improvement in the electric vehicle market.
