This study on electric cars demonstrates their reliability compared to thermal cars

A Tesla could now drive longer than a conventional combustion engine car, a discovery that challenges conventional wisdom about the reliability of electric vehicles. Analysis of 300 million technical inspections in Great Britain shows that technological progress is changing the market. The first electric models certainly suffered from a reputation for fragility, but the situation has radically changed.

Modern electric cars are on par with combustion engines

The study's figures speak for themselves. A recent electric car has an average lifespan of 18.4 years, almost identical to the 18.7 years of a gasoline vehicle. Diesel models come in slightly behind with a life expectancy of 16.8 years. Even more impressive, electric vehicles travel an average of 124,000 kilometers during their lifetime, surpassing the 116,000 kilometers of gasoline cars.

This meteoric rise can be explained by several factors. Manufacturers have rapidly improved their technologies. Each new generation of electric vehicles reduces the risk of breakdown by 12% compared to the previous one. This is a rate of development that is significantly higher than that of thermal cars, which are only progressing by 6.7% for petrol and 1.9% for diesel.

The intensity of use also has less of an impact on electric vehicles. Increasing the daily mileage by 1.6 kilometres increases the risk of breakdown by 8.4% for a petrol car and 6.4% for a diesel. Electric vehicles limit this increase to only 2.5%. A resistance to wear that can be explained by their simpler architecture, with fewer moving mechanical parts.

Marked differences between manufacturers

Tesla dominates the ranking of manufacturers in terms of longevity. The American brand is clearly ahead of its competitors in the electric segment. On the thermal side, Skoda is the benchmark for diesel while Honda leads the way in gasoline. These significant differences demonstrate the importance of industrial know-how, beyond the technology itself.

Tesla's success is no accident. Its partner CATL has invested massively in research and development to optimize its batteries. Result: the brand claims accumulators designed to last longer than the vehicle itself.

A longer lifespan mechanically reduces the total cost of ownership, a decisive argument for convincing buyers. Indeed, if the entry ticket for the purchase of an EV is more important, the study shows us here the possibility of using the car longer than its thermal counterparts.

• Electric cars now reach an average lifespan of 18.4 years, compared to 18.7 years for gasoline
• Their average mileage of 124,000 km exceeds that of gasoline vehicles (116,000 km)
• Tesla is establishing itself as the most reliable electric manufacturer, ahead of all the competition
