New Study Suggests High-Mileage EVs Age Better Than Combustion Cars

A fresh analysis out of the United Kingdom is challenging the widespread belief that electric vehicles struggle with long-term durability. Researchers examined data drawn from a massive pool of vehicle inspections — roughly 47 million of them — to compare how battery-powered cars and conventional gasoline models hold up as the miles pile on.

The findings point in a direction many EV skeptics may not expect: rather than degrading faster, electric cars appear to maintain their condition at least as well as, and in some cases better than, their internal combustion counterparts over time. That outcome runs counter to the common worry that battery degradation and costly repairs make high-mileage EVs a risky proposition.

The study adds weight to the argument that concerns about EV longevity may be overstated, particularly as battery technology matures and real-world reliability data accumulates. For shoppers weighing whether to buy used, the takeaway could be a meaningful shift in how they view an electric car’s second act — one that looks increasingly durable rather than disposable.
