The claim that electric cars are dangerous due to a high fire risk is often put forward by opponents of electric cars. But according to the Swedish Civil Contingencies Agency (MSB), gasoline or diesel-powered cars are 19 times more likely to catch fire compared to electric or plug-in hybrid cars.
In 2022, only 24 electric or plug-in hybrid cars caught fire in Sweden, which accounted for approximately 0.004 percent of all such vehicles in the country. On the other hand, around 0.08 percent of fossil fuel-driven cars caught fire. The number of fires in electric cars has remained consistent at around 20 per year for the past three years, despite a nearly doubled number of electric cars in Sweden, totaling nearly 611,000. The MSB includes trucks and buses in their compilation, noting that the majority of these vehicles are still diesel-powered.
