by How the Study was Conducted
Have you ever wondered which cars in the US are actually driven the most? A new study by iSeeCars, covering over 2.1 million three-year-old vehicles, provides the answer. The results turned out to be interesting, even considering certain caveats: gasoline cars generally have significantly higher mileage than electric ones.
To compile the ranking, iSeeCars analyzed odometer readings from over 2.1 million three-year-old cars sold in 2025, calculating the average annual mileage by model and engine type. Models with low sales volume were excluded from the analysis.
Important Caveat
However, there is a significant nuance worth keeping in mind before drawing deep conclusions. The study only considers three-year-old cars that changed owners in 2025, thus capturing the driving habits of people who decided to sell them. Owners who kept their cars are not included in the sample at all, and it’s impossible to determine if they accumulate more or fewer kilometers than those who sold. For example, a Mustang sold with an average mileage of 2,092 miles per year says a lot about that specific owner, but nothing about the one who keeps their car in the garage for the next decade.
Most and Least Used Cars
Perhaps the most interesting finding is the difference in mileage between the most and least used cars. The Chrysler Pacifica tops the list as the most used gasoline car with an average of 20,872 miles (33,590 km) per year, which is 56.7% higher than the average for gasoline cars — 13,323 miles (21,441 km). For comparison, the least used gasoline car is the Ford Mustang with an average mileage of only 2,092 miles (3,366 km) per year, which is 84.3% below the average. While it’s logical that the Mustang isn’t used as often, one might expect new owners to drive them more frequently, as this model is quite practical for a sports car.
Among other most used gasoline models are the Chrysler Voyager (20,549 miles/33,070 km), Chevrolet Suburban (19,626 miles/31,584 km), Kia Carnival (18,884 miles/30,390 km), and Chevrolet Malibu (18,857 miles/30,347 km). These cars are primarily oriented towards transporting families, passengers, and cargo.
Mileage by Engine Type
| Engine Type | Average Annual Mileage | Comparison with Gasoline |
| Gasoline | 13,323 | — |
| Hybrids | 14,696 | +10.3% |
| Plug-in Hybrids | 11,660 | -12.5% |
| Electric Vehicles | 11,880 | -10.8% |
One of the most unexpected discoveries of the study was that conventional hybrids are actually the most used vehicles on the roads. They cover an average of 14,696 miles per year, which is 10.3% more than gasoline cars and 23.7% more than electric cars. As noted by iSeeCars executive analyst Karl Brauer:
“The fact that hybrids are used more than gasoline models shows how far the technology has advanced.”
Sports Cars and Electric Vehicles
Sports cars fill the list of least used vehicles. Following the Mustang are the Mercedes-Benz SL (3,176 miles/5,111 km), Porsche 911 (3,850 miles/6,195 km), Chevrolet Corvette (4,394 miles/7,071 km), and Lexus LC 500 (4,404 miles/7,087 km). The only non-sports cars on this list are the Mercedes G-Class (6,674 miles/10,740 km) and C-Class Convertible (7,104 miles/11,432 km).
iSeeCars also highlighted the average mileage for electric vehicles and hybrids. Among electric cars, the Tesla Model 3 (13,759 miles/22,142 km) and Model Y (13,538 miles/21,787 km) lead. The Hyundai Ioniq 5 follows with a figure of 12,271 miles (19,748 km), being the only other electric car above the segment average (11,880 miles/19,119 km). Both Teslas also exceed the average for gasoline cars, making Tesla the only electric vehicle brand whose models achieve this.
At the opposite end of the electric vehicle ranking are luxury and sports models, which are used much less frequently. The Audi RS e-tron GT covers an average of only 6,461 miles (10,397 km) per year, followed by the Lucid Air (6,877 miles/11,068 km) and the Mazda MX-30 EV (7,198 miles/11,584 km).
Leading Hybrids
Regarding hybrids, the most frequently used are the Toyota Sienna (17,368 miles/27,951 km), Toyota Highlander Hybrid (16,795 miles/27,028 km), and Toyota Camry Hybrid (16,605 miles/26,723 km). Toyota dominates the ranking, occupying five of the ten positions among the most used hybrids.

Interestingly, the data highlights not only the technical characteristics of cars, but also social patterns: family minivans and large SUVs serve as workhorses for daily commutes, while sports cars often remain “weekend toys.” At the same time, the success of hybrids, especially Toyota, indicates that consumers are increasingly choosing efficiency without compromising on mileage, which could be a signal for automakers about the need to expand hybrid lineups. For electric vehicles, the challenge of overcoming “range anxiety” remains, although Tesla is already demonstrating that with the right infrastructure, they can compete with traditional cars in terms of usage intensity.
