Rivian’s R2 hasn’t reached customers yet, but it looks like it is already exceeding expectations. Newly released EPA certification data shows the upcoming electric SUV will have more range and efficiency than originally promised.
According to the filings, first shared on the Rivian Forums, the 2027 Rivian R2 Performance trim with dual motors and all-wheel drive achieves an EPA-rated range of 335 miles (539 km) when equipped with 21-inch wheels. That figure comes in slightly higher than Rivian’s previously stated 330 mile (531 km) estimate, giving the new model an early win before it even reaches customer driveways.
Opting for the 20-inch all-terrain wheels, while smaller, drops the range slightly due to the more rugged setup, but it still achieves a respectable 314 miles (505 km).
Efficiency figures from the EPA testing offer further insight into how the R2 performs in real-world conditions. Models equipped with 21-inch wheels deliver an impressive 4.62 mi/kWh in city driving and 3.89 mi/kWh (7.43 km/kWh and 6.26 km/kWh) on the highway.
Switching to 20-inch all-terrain tires results in only a minor drop—around 4% on the highway and roughly 1% in the city.
Under the floor, the R2 is powered by a “Large” battery pack with a usable capacity of 86.8 kWh. Interestingly, EPA testing indicates total energy usage closer to 88.7 kWh, suggesting there may be a small buffer beyond the displayed 0% state of charge. Data shows the vehicle supports DC fast charging speeds of up to 210 kW, putting it in line with Rivian’s larger R1T and R1S.
Beyond the raw specs, the documents also reveal Rivian is introducing several behind-the-scenes improvements. The R2 will launch with a redesigned heat pump system aimed at improving thermal efficiency, particularly in colder climates. The updated system integrates multiple components into a more compact package and is expected to enhance cabin heating performance while reducing energy consumption.
Rivian is also planning for the full lifecycle of the battery pack. New software will include built-in battery health monitoring, while the company is developing a structured approach to second-life applications and recycling. Components that meet performance standards may be repurposed for energy storage, while others will be processed through approved recycling channels.
The R2 is expected to begin employee deliveries within the next few weeks, a common step for automakers—including Tesla—when launching a new vehicle. Broader customer deliveries are anticipated to follow later this summer, though initially limited to the U.S.
Canadian customers will have to wait until sometime in 2027 before they can get their hands on the R2.
