The U.S. Environmental Protection Agency (EPA) has officially certified Rivian’s 2026 quad-motor versions of its R1T electric pickup and R1S SUV, marking a key step ahead of the vehicles’ market launch. The approval confirms compliance with U.S. Tier 3 Bin 0 emissions standards and California’s ZEV requirements, further positioning Rivian as a strong player in the premium electric SUV and truck segments.
According to certification documents, the 2026 R1S Quad Max model equipped with 22-inch Ultra High Performance (UHP) wheels achieves an estimated range of 359 miles in “Conserve” mode and 315 miles in “All-Purpose” mode. Rivian’s quad-motor configuration—four 201-horsepower permanent magnet motors—works with the Max Pack battery, which has a usable capacity of around 140 kWh. The R1T with similar specs is expected to deliver comparable performance, although exact range figures were not disclosed.
When fitted with 20-inch All-Terrain wheels, the range estimates drop slightly, with the R1S Quad Max rated at 350 miles in Conserve mode and 300 miles in All-Purpose mode. Rivian attributes improvements in efficiency to its revised thermal management system and in-house heat pump, which aim to boost real-world performance in colder climates.
Rivian has already published base pricing for the 2026 models: the R1S SUV starts at $76,990 for the Dual-Motor Standard variant, and the R1T begins at $70,990. However, prices for the quad-motor configurations remain undisclosed. A recent video—accidentally posted by tech reviewer Marques Brownlee—offered an early look at the 2026 R1T Quad, showcasing design tweaks such as teal badging, exclusive “Launch Green” paint, and the new NACS charging port, confirming Rivian’s transition to Tesla’s connector standard.
