iSeeCars data cited by InsideEVs show used EVs sold in an average of 41.9 days in September 2026, faster than used gas cars and a year earlier. The fastest-selling EV models were the Audi Q4 E-Tron Sportback, Toyota bZ4X and Lexus RZ 300e; no Tesla made the top 10. Used EV prices rose 9.8% year over year, though the data does not establish why buyers chose particular models.
Used electric vehicles sold faster than used gasoline cars in September 2026, according to iSeeCars data reported by InsideEVs, and the quickest-selling models were not Teslas. The Audi Q4 E-Tron Sportback led the list, followed by the Toyota bZ4X and Lexus RZ 300e, offering a snapshot of which used EVs moved most quickly as the segment’s prices rose.
Used EVs spent an average of 41.9 days on dealer lots, the report said. That was 10.1% less time than in September 2025. Used gas cars took an average of 54.8 days to sell, and their average selling time increased 19.9% year over year. The figures describe time on the lot, not total sales volume or the share of all used-car transactions.
Prices also moved differently by drivetrain. The reported average price for used EVs was up 9.8% year over year in September, twice the 4.8% increase for used hybrids. Used gasoline-car prices rose 0.3% over the same comparison period. The report does not provide the underlying price levels or explain how vehicle age, mileage or model mix affected those changes.
After the Audi, Toyota and Lexus models, other vehicles appearing among the fastest-selling EVs included the Honda Prologue, BMW iX and Polestar 2. No Tesla, Lucid or Rivian model appeared in the top 10, according to the report. At the opposite end, the Cadillac Escalade IQ was the slowest-selling model listed, followed by the GMC Sierra EV, Chevrolet Silverado EV and Volvo EX90.
What Faster Sales Mean for Used EVs
The figures suggest that used EVs are attracting buyers quickly relative to used gasoline cars, even as the EV selection remains much smaller. That can matter to shoppers weighing an electric vehicle against a conventional car: vehicles that spend less time on lots may be harder to find, while rising average prices could affect the savings buyers expect from purchasing used.
The model rankings also temper the idea that used-EV demand is driven only by Tesla. The fastest-moving vehicles included models from several established automakers. But a speed ranking alone does not show why buyers chose them, whether they sold at asking price, or how many units changed hands. It is a measure of market movement, not proof that any one model is broadly more desirable.

Supply and Model Mix Shape the Picture
The InsideEVs report notes a large gap between the number of used gas and diesel cars listed on Autotrader and the number of used EVs: 1,384,383 versus 44,434, respectively. Those are listing counts cited by the report, not a complete count of vehicles available across every marketplace. The smaller EV inventory means shoppers have fewer examples and models to compare, which can affect how a time-on-lot comparison reads.
iSeeCars analyst Karl Brauer said fuel prices may be contributing to the changes and that the EV market had recovered from disruption after federal incentives were lost a year earlier. These are explanations offered by the analyst, not causal findings established by the figures. The report also points to rising used prices for the Tesla Model S and Model X—22% and 18%, respectively, year over year—as a possible factor in why Tesla models did not lead the fast-selling rankings.
What the Rankings Cannot Tell Us
The figures do not show the number of vehicles sold for each model, transaction prices, or whether the fastest-selling cars were listed in unusually low quantities. The report also does not specify how its model ranking handles differences in age, mileage, trim or regional supply. Without those details, the list should be read as a measure of reported selling speed, not a direct measure of total demand.
The data also cannot establish that higher fuel prices caused the change, or that a particular vehicle’s size, styling or interior explains its ranking. The quoted analyst presents fuel costs and the recovery from incentive-related demand disruption as likely influences. Those explanations remain interpretations rather than findings proven by the numbers presented.
Watch Inventory and Later Reports
Further monthly data will show whether the September pattern continues: faster sales for used EVs, rising prices, and non-Tesla models among the quickest movers. Readers comparing vehicles can track both listing prices and time on market, while remembering that averages and national rankings may not reflect local inventory or the condition of an individual car.
The report does not announce a specific next data release or forecast how prices will move. Until more detail is available, the September figures are best treated as a snapshot of the used-car market rather than a guarantee that a particular EV will sell quickly or hold its value.
