Rivian reshaped its R1 financing grid for September, cutting the Dual rate by a full percentage point while introducing a promotional rate on the Quad for the first time since the zero-percent offers that opened the year expired.
The new slate, published on the company’s US offers page and valid through September 30, keeps the R1 Tri at 1.99% APR on a 60-month term — the rate Rivian set on August 12 when it doubled the Tri from 0.99%.
The Dual drops to 2.99%, while the Quad enters the September grid at 3.99%.
All three offers apply exclusively to new 2026 model-year R1T and R1S vehicles ordered through the R1 Shop — as the EV maker continues its push towards clearing inventory of the model after opening the configurator for the 2027 version.
Buyers must order and obtain an approved financing offer between September 1 and September 30, and take delivery by the same date — the close of the third quarter.
A $1,500 lease rebate runs alongside the financing offers on Dual and Tri builds, replacing the $3,000 contribution Rivian offered in August.
The September terms were first flagged on X by Rivian owner and X user Chris Hilbert, who has been tracking the company’s monthly offer changes throughout the past months.
Financing Tier by Tier
Rivian’s September terms set out the monthly cost of each offer at $17.54 per $1,000 financed for the Tri, $17.99 for the Dual and $18.45 for the Quad, each over 60 months.
The Tri rate covers the R1T and R1S Tri Max only.
Rivian’s own example prices an R1T Tri Max at $102,885 including the $1,895 destination charge, financed at $102,385 after a $500 order deposit, producing a monthly payment of $1,795.60.
The Dual’s 2.99% rate spans every Dual variant still in 2026 inventory: Dual Standard, Dual with Large Battery, Dual with Large Battery and Power Upgrade, Dual with Max Battery and Dual with Max Battery and Power Upgrade.
An R1T Dual Standard at $74,885 works out to $1,337.92 a month on $74,385 financed, per the company’s illustration.
The Quad offer, restricted to the Quad Max, lists an R1T Quad Max at $117,885, financed at $117,385 for $2,164.84 a month.
Each offer requires a $500 order deposit.
No additional down payment is required unless the amount financed exceeds the vehicle price.
Taxes, registration, documentation and other fees sit outside the advertised figure.
What Changed From August
The most significant shift is on the Dual line.
August had priced Dual builds at 3.99% APR, a rate Rivian had raised from 2.99% at the start of that month.
September reverses the increase, returning the Dual to 2.99%.
The Quad’s 3.99% offer is new.
August carried no promotional financing rate on the halo quad-motor configuration.
Rivian last offered the Quad a zero-percent rate in the opening months of the year, before the promotional structure shifted to tiered rates across the lineup.
The Tri holds at 1.99%, unchanged since the EV maker doubled the rate from 0.99% on August 12.
The 0.99% rate had itself been a carry-over from a late-July push that paired sub-1% financing with $1,000 discounts on any new R1.
September’s financing grid therefore runs 1.99% for Tri, 2.99% for Dual and 3.99% for Quad — a clean one-point spread between each tier, replacing the two-tier structure August used.
Lease Rebate Halved but Broadened
Rivian cut its lease rebate from $3,000 to $1,500 while expanding the number of configurations that qualify.
August’s $3,000 contribution applied only to the R1 Tri Max on 24- or 36-month lease terms.
September’s $1,500 covers every Dual variant — Dual Standard, Dual with Large Battery, Dual with Large Battery and Power Upgrade, Dual with Max Battery and Dual with Max Battery and Power Upgrade — alongside the Tri Max, on 24- or 36-month leases of new 2026 R1T and R1S vehicles.
The Quad is excluded from the lease rebate, even as it gains a financing offer.
Buyers must order and obtain an approved lease through Rivian’s approved lender between September 1 and September 30 and take delivery by September 30.
The rebate is applied to the amount due at signing and cannot be combined with other public offers unless Rivian permits.
What Carries Over
Three August promotions survive alongside the reshaped financing grid.
The Stealth Package exterior discount of up to $2,200 and the Road Trip Package accessory offer of up to $2,500 both remain on the September offers page, continuing unchanged from August.
The three months of complimentary charging on the Rivian Adventure Network, which Rivian introduced on August 21 for buyers of 2026 R1 vehicles or pre-owned R1 models from 2024 or earlier, also persists.
The ordering window closes on September 12, well before the rest of the September slate expires on September 30.
Quarter-End Context
September closes Rivian’s third quarter, and every offer on the page shares a September 30 delivery deadline — the same structure the company used in August when each incentive also required delivery by that date.
The offers land against a backdrop of soft R1 demand and an ongoing model-year transition.
Rivian announced the 2027 R1T and R1S on August 13, retiring the Dual, Tri and Quad powertrain names in favour of a Premium, Performance and Quad ladder aligned with the R2 SUV.
Purchase prices held flat. However, every 2027 lease rose by $100 a month — a uniform increase worth $3,600 over a 36-month term.
The higher 2027 lease costs give Rivian additional room to sweeten terms on remaining 2026 stock.
The Dual Standard model — discontinued from the 2027 lineup entirely — still appears in the September financing and lease offers as the company works through leftover units.
Combined R1S and R1T deliveries fell 6.3% year over year in the second quarter, with the R1T down 30.4% and the R1S about flat, extending a 15.1% full-year decline for the nameplate in 2025.
Full-year delivery guidance stands at 65,000 to 70,000 vehicles.
