Rivian R1T and R1S 2027: the cheapest battery goes, the entry model climbs in price

Rivian has submitted the 2027 model year R1T pickup and R1S SUV for EPA certification, and the paperwork has revealed a new naming scheme for the lineup. This is not the launch yet: the official website still lists the current Dual, Tri and Quad range, and there is no separate announcement of the 2027 cars as of this check.

The documents were posted by Rivian Forums user kanundrum — EPA certification is usually one of the last formal steps before a new model year enters production. The filings introduce the Premium and Long Range labels, the same words Rivian already uses on the more affordable R2 crossover. Test group VRIVT00.0172, dated July 2, lists six configurations badged R1T Premium and R1S Premium on 22-inch, 20-inch and 20-inch all-terrain wheels. An accompanying CARB sheet ties the Premium name to the 665 hp dual-motor version with the Large pack, while Long Range goes to the variant with the bigger battery. The Tri and Quad designations are unchanged in the paperwork.

The most visible change is the disappearance of the entry-level 92.5 kWh Standard pack with lithium iron phosphate cells. For the 2027 model year the 105.5 kWh Large pack becomes the starting battery, and the 140 kWh Max moves to the options list. Rivian explains the reshuffle directly in the certification material: the R1 range has to sit clearly above R2.

The retreat from the small battery has already happened in the current lineup — Rivian quietly dropped the Dual Standard versions in late June, and the entry point rose by roughly $7000. The official configurator shows the R1T Dual from $79,990 and the R1S Dual from $83,990. Three-motor cars start at $100,990 and $106,990. The four-motor R1T and R1S are priced from $115,990 and $121,990.

Certification promises no extra power. The dual-motor versions keep 533 hp as standard and 665 hp with the Performance pack, but Rivian now calls the units High-Efficiency motors instead of the previous Enduro name. The three-motor version stays at 850 hp and 1495 Nm, the four-motor at 1025 hp and 1624 Nm, and the front and rear gear ratios carry over. Instead, the maker points to revised thermal management logic and optimized highway energy use — work on efficiency rather than on numbers for the brochure.

Range on the current cars stays where it was. Depending on version and wheels, the R1T carries an EPA figure of 329 to 420 miles — roughly 529 to 676 km. The seven-seat R1S is quoted at 329 to 410 miles, or 529 to 660 km.

The rest of the changes in the documents are small but telling. Wheels previously listed as 22-inch Sport are now simply Standard, and exact tyre sizes are given for every configuration. The NACS port remains standard, but instead of a CCS adapter the 2027 cars come with an SAE J1772 adapter, part number PT01472026. The onboard charger is unchanged at 11.5 kW from a 240-volt, 48-amp supply.

Rivian is preparing the model year switch against weak demand for its flagships. Cox Automotive estimates that the company handed over about 7402 R1S and R1T units in the second quarter, 6.3% fewer than a year earlier, with the pickup down 30.4% to 1219 cars. Full-year R1 deliveries fell around 15.1% in 2025. Inventory is being cleared in advance: discounts on 2026 cars run up to $5000, joined by a $3000 lease credit on Tri and Dual with the Performance pack, 0% financing over 60 months on leftover 2025 stock and a 1.99% rate on selected 2026 versions. The company has not named a launch date: last year it presented the model year on July 8, and certification usually means the announcement is days away, so talk of August remains a forecast.

For the buyer the practical question is not the new trim name but the final range, charging speed and price. With the cheapest battery gone, the entry R1 becomes more expensive but travels further between plugs. Waiting for the 2027 car makes sense until the official configurator appears: for now the documents point to a careful update of the lineup rather than a change of generation.
