Reliability and longevity concerns may once have been among the most common reasons for not buying an electric vehicle. A new study published in Nature Energy claims that the reliability of battery-powered electric vehicles (BEVs) has increased considerably and they now have comparable longevity to conventional internal-combustion-engine vehicles.
The study examined almost 300 million test logs from the UK Ministry of Transportation (MOT) between 2005 and 2022. This data gave researchers a thorough evaluation of each car’s “health” on UK roads, allowing them to compare survival rates across different powertrains and predict vehicle longevity.
Teams from the University of California San Diego, the University of Birmingham, the London School of Economics and Political Science, and the University of Bern in Switzerland concluded that battery-powered electric vehicles (BEVs) can travel an average of 124,000 miles (199,500 km) – more than the typical gasoline car of the same generation – in their lifetime, and have an average lifespan of 18.4 years, compared to 18.7 years for gasoline cars and 16.8 years for diesel cars.
