In news that is sure to either surprise or delight you, depending on where you sit on the EV vs ICE divide, a recent study from the U.K. has found that high-mileage electric cars are more reliable than their combustion counterparts. On the face of it, the evidence flies in the face of those put off by higher-mileage EVs, due to concerns over wear and tear.

However, there’s an important catch: the study was carried out using the UK’s MOT test data. While the sample size is impressive, with 47.4 million MOT tests analyzed, you do need to remember what the inspection looks out for and, importantly, what it doesn’t.

An MOT is a legally required annual test for cars over three years of age registered in the U.K. It ensures a car meets minimum standards of safety and emissions. What an MOT doesn’t do is test things like an EV’s remaining battery capacity or recharging health. Similarly, for an ICE car, it doesn’t factor in engine performance or the condition of a vehicle’s transmission.

What The Data Says

While it may not paint the whole picture, there is some merit to the study, suggesting that high-mileage EVs shouldn’t necessarily be skipped over when browsing the classifieds. The research, which was carried out by transport consultancy New AutoMotive and commissioned by the British Vehicle Rental and Leasing Association (BVRLA), was carried out on cars aged between three and eight years old.

For EVs with between 90,000-120,000 miles (145,000-193,000 km), only 16.5 percent failed. Compare that with 22.1 percent of combustion-powered cars, and that’s a 25 percent lower relative rate. The gap between the two drivetrain types increases the more miles are added. For EVs that had more than 120,000 miles on the odometer, the MOT test failure rate stayed roughly constant, with 16 percent failing, while ICE vehicles had a higher failure rate of 23.5 percent.

The study also found that, at lower mileages, the difference between electric and combustion was negligible. Between 20,000-40,000 miles / 32,180-64,370 km the EV failure rate was 12 percent, with ICE cars at 11.7 percent.

The Full Picture

On the failure rate alone, it would appear that high-mileage EVs aren’t as unreliable as their gas-powered alternatives. However, as an MOT test doesn’t factor in battery health, one of the largest components of high-mileage EVs wasn’t accounted for. An MOT test still checks safety and wear items, including tires, steering, suspension, brakes, lights, and the condition of a vehicle’s structure.

However, wear items are still a big concern. The research found that EVs recorded nearly twice as many tire defects as ICE vehicles. In lower-mileage EVs, brakes were also flagged. This was likely due to the fact that EVs mainly rely on regenerative braking, meaning that the friction brake components were less likely to be used as much, and therefore more susceptible to corrosion-related wear.

While the research was carried out by the independent transport consultancy New AutoMotive, it’s also perhaps prudent to note who commissioned the study. The British Vehicle Rental and Leasing Association (BVRLA) represents over 1,000 companies operating within the UK’s vehicle rental, leasing, and fleet management sectors. Many of those companies likely have fleets of high-mileage EVs ready to enter the used car market.

“The important thing about this study is that we can separate age from mileage,” said Ben Nelmes, chief executive at New AutoMotive, speaking to Fleet News. “Looking simply at the headline MOT numbers gives a misleading picture because Britain’s electric cars are much younger than its petrol and diesel fleet, while comparing cars by age alone misses the fact that EVs have typically covered considerably more miles.”

“Once we compare cars of the same age and mileage, something striking happens. At lower mileages, there is very little between petrol and electric cars, but beyond around 60,000 miles (96,560 km) the failure rate for EVs flattens while the petrol failure rate continues to rise. High mileage isn’t a proxy for poor condition in the way buyers have traditionally assumed. The data suggests the mechanical simplicity of an electric drivetrain starts to become increasingly valuable as cars accumulate miles.”

Battery degradation has long been one of the reasons new car buyers have held out on purchasing an EV. However, data from a new study reveal that the top-performing EVs lose less than 5 percent of their range after 93,205 miles (150,000 km) of driving, meaning battery packs will easily last the average life of most new cars.

The study, published by Aviloo, has been labeled the largest independent study of used EV batteries ever conducted. More than 500,000 battery tests have been published, and the results show how 20 of the industry’s most popular EVs perform.

The Hyundai Ioniq 5 performed best after 31,068 miles (50,000 km) of testing, retaining 97.1 percent of its original usable capacity. Other strong performers after 31,068 miles included the Mercedes-Benz CLA at 96.6 percent, the Hyundai Kona EV at 96.3 percent, the Audi Q8 e-tron with 95.7 percent, the BMW i4 with 95.6 percent, and both the Volvo XC40 Recharge and VW ID.4 at 95.2 percent battery retention.

After 93,205 miles of driving, the Mercedes-Benz CLA came out on top with a battery health of 94 percent. This placed it ahead of the Hyundai Ioniq 5 (93.6 percent), Hyundai Kona EV (93 percent), Volvo XC40 Recharge (92.8 percent), Ford Mustang Mach-E (92.5 percent), and the Polestar 2, also at 92.5 percent.

Teslas Disappoint

Several popular EVs did not perform as well as the competition. Most notable was the Tesla Model Y, which retained just 90.3 percent of its battery capacity after 93,205 miles, and the Tesla Model 3, which retained 88.9 percent of its battery capacity. Other poor performers included the Renault Zoe (87.3 percent), Mini Cooper SE (87.1 percent), and Nissan Leaf (86.7 percent), all of which have relatively small batteries.

Importantly, the results of this study don’t mean every Mercedes-Benz CLA will have 94 percent battery health after 93,205 miles, or every Peugeot e-208 will have 90.7 percent battery health. The study examined the median across all vehicles and found that good and bad examples of the same car can have battery health ratings that vary by as much as 13.5 percent. Nevertheless, the study demonstrates just how good current EV batteries are.

Cheap to buy and cheap to own are two different things, and the gap between them is where most new car shoppers get caught out. If you’re shopping in the US and want something that costs almost nothing to keep on the road, there’s one clear winner: the Fiat 500e. Yes, the pint-sized three-door electric hatchback that virtually nobody is buying happens to be the cheapest new car in America to live with.

Fiat moved 150 of them in the first half of the year, down 81 percent from the 788 it managed over the same stretch in 2025, a figure that was hardly worth celebrating in the first place.

A recent study from Self.Inc set out to determine the average running costs of 50 popular new cars sold across the country. We’re not sure how these 50 were selected, but the results show that the 500e has annual running costs of just $3,557, easily beating the next-most-affordable option, the Honda Civic Hybrid, with average annual costs of $4,833.

A key reason for the 500e’s affordability is its efficiency. The car is small and, on average, costs $779 to charge. Average annual insurance at $779 is also well below the industry average, and annual maintenance of $1,275 is also low. Annual fees and taxes of $724 are higher than some of the competition, but that’s not enough to outdo the other savings.

Average Running Costs By Brand

Positioned in a surprising third place was the Hyundai Elantra N with average annual running costs of $4,904. We’re not sure how the Elantra N made the list, as opposed to the standard Elantra, particularly given it can use quite a lot of fuel when driven as most N owners drive. Nonetheless, the average maintenance cost is low at just $1,278, which helps.

Other affordable cars to run in the US include the Nissan Versa at $4,949 in annual costs, the Toyota Camry Hybrid at $5,031, the Honda Accord HEV at $5,047, and the gas-powered Honda Civic at $5,062. Included in the affordable options are also the Mini Cooper, Kia K4, and Mazda3.

What About The Most Expensive?

At the other end of the spectrum are some very expensive cars to run. The Porsche 911 was listed as the most expensive car to run, with average annual costs of $10,832, positioning it ahead of the Audi RS7 at $10,334, the Cadillac CT5-V Blackwing at $10,265, the Chevrolet Corvette at $10,213, and the Lucid Air at $10,049, primarily due to high insurance fees for the luxurious electric sedan.

Compared to the last time the study was conducted in 2024, average annual fuel costs have fallen from $2,246 to $1,727. While this is good news for car buyers, annual insurance costs have jumped from $1,763 to $2,219, and annual maintenance costs are also up from $1,633 to $1,817. Annual fees and taxes have also increased from $820 to $1,151.

The study also sheds light on differences in ownership costs among EVs, gas-powered vehicles, and hybrids. After analyzing each of the 50 models, hybrids came out on top with average annual running costs of $5,734, less than the $6,189 for EVs, primarily due to cheaper insurance, fees, and taxes. Gas-powered vehicles came last, with an average cost of $7,025.
