Electric cars are significantly less likely to catch fire compared to traditional gasoline-powered vehicles. Various studies and statistics support this assertion:

Fire Incidence Rates:
- Data indicates that electric vehicles (EVs) are involved in approximately 25 fires per 100,000 sold, whereas gasoline vehicles experience around 1,530 fires per 100,000 sold. This stark contrast highlights that EVs are about 60 times less likely to catch fire than their gasoline counterparts .
Nature of Fires:
- The fires that do occur in EVs typically arise from severe external damage or accidents, rather than spontaneous ignition. Lithium-ion batteries, which power most EVs, require significant heat to ignite, making them less prone to immediate combustion compared to gasoline, which ignites upon contact with a spark or flame .
Safety Features:
- EVs are designed with advanced safety measures to prevent fires. These include battery management systems that monitor temperature and conditions to avoid overheating and thermal runaway, as well as structural designs that protect battery packs during collisions .
Comparative Risks:
- A study highlighted by Tesla claims that their vehicles are 11 times less likely to catch fire than gasoline cars when comparing incidents per billion miles driven. Specifically, there are about five EV fires for every billion miles traveled, compared to 55 fires for gasoline cars .
Public Perception vs. Reality:
- Despite the lower risk of fire in EVs, media coverage often exaggerates incidents involving electric vehicle fires, leading to misconceptions about their safety. In reality, the overall fire risk associated with gasoline vehicles remains significantly higher .

In summary, electric cars present a lower fire risk than traditional vehicles, supported by statistical evidence and advancements in safety technology.
