2024 Rivian R1S Fuel Economy

EPA ratings by trim

City and highway are EPA's adjusted label figures; combined is the 55/45 blend printed on the window sticker. For electric and plug-in trims the MPG columns are MPGe, and the kWh per 100 miles is the figure a charging cost actually turns on; EPA measures it at the wall, so charging losses are already in it. Unrounded combined figures, where EPA publishes them: R1S AT Performance Dual Standard Plus (20in) 65.2626; R1S All-Terrain Dual Large (20in) 68.4496; R1S All-Terrain Dual Max (20in) 73.0748; R1S All-Terrain Dual Standard Plus (20in) 65.2626; R1S All-Terrain Performance Dual Large (20in) 68.4496; R1S All-Terrain Performance Dual Max (20in) 73.0748; R1S All-Terrain Quad Large (20 inch) 62.7679; R1S Dual Large (21in) 77.9742; R1S Dual Large (22in) 75.3343; R1S Dual Max (21in) 82.4693; R1S Dual Max (22in) 77.8207; R1S Dual Standard (21in) 74.5618; R1S Dual Standard (22in) 70.1735; R1S Dual Standard Plus (21in) 76.9421; R1S Dual Standard Plus (22in) 72.1051; R1S Performance Dual Large (21in) 77.9742; R1S Performance Dual Large (22in) 75.3343; R1S Performance Dual Max (21in) 82.4693; R1S Performance Dual Max (22in) 77.8207; R1S Performance Dual Standard (22in) 72.1051; R1S Performance Dual Standard Plus (21in) 76.9421; R1S Quad Large (20in) 64.3506; R1S Quad Large (21in) 71.1132; R1S Quad Large (22in) 68.2876.

What the rating costs per mile

The rating divided by a price, times your miles. It starts at EIA's current U.S. averages and EPA's 15,000 miles so the right-hand column is comparable; type your own pump price, home rate and mileage over them.

Fuel only — before depreciation, insurance, maintenance or tires, which the True Cost per Mile Calculator adds. Most drivers land below the rating; the True MPG Calculator measures your own from two fill-ups. The EV vs. Gas Cost Calculator sets the electric trim against a gasoline one over a year.

EPA's own figures, and why they differ

The “EPA's figure” column is EPA's annual fuel cost from the same file: 15,000 miles, 55% city, and the national fuel price fueleconomy.gov was using on the day the file was built (2026-09-29). fueleconomy.gov recomputes its page every week at the current price, so its number and the file's drift apart between file dates; the middle columns here use a price you can see and change, which is the only honest way to compare two cars. EPA also prints a five-year “you save/spend” against the average new vehicle (saves $7,500 for the R1S Dual Max (21in)); it rests on the same assumptions and is not repeated here as a result.

Every figure on this page is a rating, not a measurement of any particular car. The site never calls a rating wrong; it shows what your own price and miles do to it. See the model on fueleconomy.gov.
