2026 Rivian R1S

R1S is Rivian's three-row electric SUV for buyers who want adventure packaging and EV range without a traditional luxury badge. Trade-offs: price, charging-network strategy versus Tesla, and configuration complexity (battery, motors, wheels).

What's confirmed (EPA 2026)

EPA lists many R1S rows. Representative examples:

  • All-Terrain Dual Large (20in): 76 MPGe combined (82/70), 44 kWh/100 miles
  • All-Terrain Dual Large Plus (20in): 72 MPGe (76/67), 47 kWh/100 miles
  • All-Terrain Dual Max (20in): 78 MPGe (82/73), 43 kWh/100 miles
  • Dual Large / Performance Dual Large (22in) class rows reach about 85 MPGe combined (94/77) on some listings
  • Tri/Quad and All-Terrain performance packs trend lower (fetched set includes combined figures down toward the high 60s–70s)

Wheel size and All-Terrain packaging move efficiency — match the exact EPA string.

Practical notes

Prefer R1S over R1T for this batch (pickup R1T remains a separate catalog stub). Range claims vary widely by battery; use EPA config, not a single “up to” marketing number.

Safety

Secondary sources mention strong IIHS recognition for Rivian products — DriveRevu cites only pages we fetch. Treat crash awards as Score pending until an IIHS/NHTSA 2026 R1S page is attached in a follow-up.
