effective there-and-back radius
The 2026 Rivian R1S Quad Max (22in UHP) is rated at 544 km (338 mi) on the EPA test cycle. That's a laboratory figure — in mixed real-world driving expect roughly 517 km, less in winter or at sustained highway speed. On a road-network range map that's rarely a neat circle — terrain, highways and coastlines shape where one charge can actually take you. For a trip out and back home without charging, plan around an effective radius of about 272 km.
