If you’re still sceptical about electric cars (EVs), here’s something to think about: they’re now just as reliable as petrol and diesel cars. That’s the takeaway from a major international study, which found that even with heavy use, EVs on average match the lifespan of their internal combustion engine (ICE) counterparts.
Researchers from the University of Birmingham, London School of Economics, University of California San Diego, and Switzerland’s University of Bern reviewed over 300 million MOT test records from 2005 to 2022. While early EVs didn’t have the best track record, the study found that their reliability has drastically improved. The likelihood of a tech failure dropped by 12% per year, compared to 6.7% for petrol cars and 1.9% for diesels during the same period.
Now, the average lifespan of an EV is projected to be 18.4 years, with a mileage of up to 124,000 miles—outperforming petrol cars in this area. Interestingly, despite Tesla’s mixed reputation for reliability, the study found its vehicles to be the most durable EVs. Among ICE cars, Audi and Skoda topped the rankings.
Dr. Viet Nguyen-Tien from the London School of Economics called the findings a “critical insight into the lifespan and environmental impact of electric vehicles”, saying EVs are “no longer just a niche option.”
Professor Robert Elliott from the University of Birmingham highlighted that although manufacturing EVs produces higher emissions upfront compared to ICE cars, their longer lifespan helps offset this, making them a greener choice over time. He said, “a long-lasting electric vehicle can quickly offset its carbon footprint, contributing to the fight against climate change – making them a more sustainable long-term option”.
Elliott also noted "Our findings offer consumers reliable data to make informed decisions about their vehicle purchases, whilst policymakers can use our insights to shape regulations and incentives that promote the adoption of durable and environmentally friendly vehicles and plan ahead their end-of-life treatment."
