2026 Rivian Range Estimates Revealed for All Configurations

Rivian’s 2026 lineup just got its EPA paperwork finalized, and now we’ve got a clear look at range estimates for the Dual, Tri, and Quad motor setups across both the R1T and R1S. These aren’t the final sticker numbers yet, but they’re based on the official 2-cycle EPA test, which gives us a solid look at relative performance across the board.

So what’s the 2-cycle test? It’s the original EPA method for measuring EV range and still forms the base of the final number you see on a Monroney sticker. It utilizes two driving cycles: one simulating city driving (characterized by stop-and-go traffic at low speeds) and another simulating highway conditions. While the 5-cycle test adds more factors like AC usage and aggressive acceleration, the 2-cycle is a great apples-to-apples comparison for different configurations under controlled conditions. And in these documents, it’s the raw 2-cycle result that Rivian submitted.

Let’s break down the numbers:

A few key takeaways:

• R1S Tri Max on 22s leads the pack at 371 miles, the highest range of any configuration.
• Dual motor variants still offer strong range numbers for the price, especially on 22s.
• All-Terrain tires consistently shave off 25 to 45 miles, depending on configuration.
• Quad Motor on UHP tires is impressive, especially considering the added performance, 352 miles on the R1S is nothing to scoff at.
• R1T variants come in slightly lower than R1S, likely due to aero differences and weight balance.

We’ll wait to see how Rivian markets the final adjusted numbers, but if you’re shopping or configuring a 2026 R1, this table is your best early look at how each setup compares.
