Rivian sold an estimated 4,537 vehicles in the United States in August, down 6.0% from a year earlier and 3.5% from July, according to data published on Tuesday by Motor Intelligence.
August was the second full month of R2 customer deliveries and ended a two-month streak of year-over-year gains.
July’s 4,700 units — the strongest month of the year — had posted an 11.9% year-over-year increase in what was the first full calendar month of R2 handovers.
Motor Intelligence has previously revised its historical estimates for several brands in recent months, including a June adjustment that added more than 600 units to Rivian’s tally and turned a reported decline into a 22.1% year-over-year gain.
Year-to-date, Motor Intelligence estimates place Rivian’s US retail sales at 28,929 units through eight months, still 4.4% below 30,249 over the same period in 2025.
The Monthly Trajectory
Rivian’s 2026 monthly US sales series has traced a clear arc shaped by the R2 ramp.
January opened at 2,516 units — down 18% year over year — followed by 2,700 in February, 3,628 in March and 3,480 in April.
May dropped to 3,100 before Rivian opened customer orders of the R2 in early June.
June jumped to 4,268, July climbed further to 4,700, and August pulled back to 4,537 units.
Five of the eight months have logged year-over-year declines.
Every month since the R2 reached buyers has posted volumes above 4,000, a threshold Rivian crossed only twice in the January-to-May stretch.
Motor Intelligence‘s estimates cover US retail sales in its passenger-car and light-truck categories — capturing the R1T, R1S and R2 but structurally excluding Rivian’s EDV commercial vans, which are not retail vehicles.
How Rivals Fared
The same Motor Intelligence table shows all four publicly tracked EV makers declining year over year in August.
Tesla was estimated at 40,816 US sales, down 26% from 55,500 a year earlier and 3.8% from July’s 42,435.
The result extends a year-over-year decline streak that has now run through every month of 2026, even as the company rolls out the Model Y L in the US and prepares for Cybercab production.
Lucid Motors was estimated at 837 US sales, down 16% from 993 a year ago and 2.7% from July’s 860.
The decline came despite an aggressive incentive stack that has included zero-percent financing stretched to 72 months and up to $10,000 in company credits on unsold 2026 Gravity SUVs.
Polestar was estimated at 295 US sales, down 48% from 570 a year earlier and 9.5% from July’s 326.
The Geely-backed brand is selling through its final US inventory after the US Department of Commerce declined to grant an exemption from the Connected Vehicle Rule, barring sales from the 2027 model year onward.
Discounts of up to $25,000 off MSRP have not reversed the slide.
Rivian’s 6% decline was the shallowest among the four, and the only one driven by a month-over-month pullback from a recent high rather than a structural downturn.
R2 Ramp Accelerates
On the production side, Rivian’s R2 ramp continued to build through August.
Vehicle identification number assignments approached 10,000 on a single production shift at the Illinois plant, according to buyer postings tracked publicly.
A Southern California buyer posted a serial number in the 9,400s assigned on August 29.
VIN assignments run ahead of finished vehicles and further ahead of customer handovers.
Founder and CEO RJ Scaringe said on the July 30 earnings call that Rivian expected to scale to a second production shift by the end of the third quarter.
However, Chief Operating Officer Javier Varela added that the second shift was not expected to contribute material volume until the fourth quarter as it will begin in the final days of September.
Rivian has guided to 20,000 to 25,000 R2 deliveries in 2026, of which 5,000 are planned for California.
R1 September Offers
Rivian enters September with reshaped R1 incentives designed to clear remaining 2026 model-year stock ahead of the 2027 R1T and R1S — which retired the Dual, Tri and Quad powertrain names in favour of a Premium, Performance and Quad ladder aligned with the R2.
September’s financing grid runs 1.99% APR for the Tri, 2.99% for the Dual and 3.99% for the Quad — a clean one-point spread between each tier.
The Dual rate returned to 2.99% after Rivian had raised it to 3.99% in August, while the Quad received a promotional rate for the first time since the zero-percent offers that opened the year expired.
A $1,500 lease rebate accompanies the financing offers on Dual and Tri builds, replacing the $3,000 contribution Rivian offered in August.
The headline amount halved, but eligibility widened — August’s $3,000 applied only to the Tri Max, while September’s $1,500 covers every Dual variant alongside the Tri Max. All offers carry a September 30 delivery deadline — the close of the third quarter.
The Guidance Math
Rivian raised its full-year delivery guidance after second-quarter deliveries topped its own outlook, lifting the range to 65,000 to 70,000 vehicles from a prior 62,000 to 67,000.
With 22,559 delivered in the first half, the raised target requires 42,441 to 47,441 vehicles across the final six months — about 7,100 to 7,900 a month, vans included.
Rivian is expected to third-quarter delivery figures in early October.
