This study into the longevity of EVs was done by University of Birmingham
A groundbreaking multi-national study by the University of Birmingham and the London School of Economics (LSE) has revealed that modern electric vehicles (EVs) now last as long, if not longer, than traditional internal combustion engine (ICE) cars. This study, published in Nature Energy, analyzed over 300 million records, including data from 30 million vehicles.

The research utilized anonymized UK Ministry of Transport (MOT) test data to assess the longevity of cars on UK roads between 2005 and 2022. While early battery electric vehicles (BEVs) struggled with reliability, rapid advancements in technology have led to significant improvements in their lifespan.
Moreover, the findings of this study highlight the impressive progress made by BEVs in terms of vehicle longevity. EVs have now reached a point where they can match the lifespans of traditional petrol and diesel vehicles, marking a pivotal shift in the journey towards sustainable transportation. The study shows that newer BEVs have comparable, if not superior, longevity to ICE vehicles.

Researchers found that BEVs have a 12 percent lower likelihood of failure per year compared to 6.7 percent for petrol cars and 1.9 percent for diesel vehicles. This indicates that, with each successive year of production, the reliability of electric vehicles continues to improve. According to Professor Robert Elliott from the University of Birmingham, the environmental benefits of BEVs are clear, especially as Europe transitions to a renewable energy mix.
Although EV production results in higher emissions initially, a long-lasting BEV can quickly offset its carbon footprint, contributing positively to the fight against climate change. The study reveals that the average BEV now lasts 18.4 years and can travel up to 124,000 miles, surpassing the mileage of traditional petrol cars.

On top of that, the study also highlights the top-performing EV brands. Tesla leads the pack among BEVs, while Audi and Skoda are the most durable in the petrol and diesel categories, respectively. These findings provide valuable insights for consumers, offering data to help them make informed decisions when purchasing a vehicle.
The research also underscores the importance of technological advancements in driving the adoption of BEVs, as well as the need for better planning in terms of fleet replacement and recycling of electric vehicles at the end of their lifespan. Dr. Viet Nguyen-Tien, co-author from LSE, emphasized that BEVs are no longer a niche option, but a viable and sustainable alternative to traditional vehicles, helping to pave the way toward a net-zero carbon future.
