It won’t be long before Rivian starts delivering the first of its new R2 SUVs to the lucky owners. After wowing everyone with its R1S and R1T, the startup is ready to enter more mainstream market segments, first with the midsize R2 this year. Last month, we got pricing and trim details for the new electric SUV: $57,990 for the R2 Performance, the only version that will be available until the $53,990 R2 Premium goes on sale in late 2026.
Both of these R2s use the same spec battery with a capacity of 87.9 kWh. At the time, Rivian said it expected at least 330 miles (531 km) of range from these models on 21-inch tires. But it seems that details of the actual Environmental Protection Agency range certification have leaked and were posted to the Rivian Forums. And from those documents, we now know that, when fitted with 21-inch wheels and performance, the official EPA range estimate will be 335 miles (539 km).
The testing also generated an official EPA range estimate for the R2 when fitted with smaller 20-inch wheels. Usually, fitting smaller wheels to an EV increases range because the rotation of each wheel causes a lot of drag that saps range, and smaller, narrower wheels disturb less air. But in this case, the 20-inch wheels drop the EPA range estimate down to 314 miles (505 km), thanks to the knobby all-terrain tires.
