Study: Electric Vehicles Involved in Fewest Car Fires
By Sean Tucker 01/28/2022 Kelley Bluebook
Electric cars have been subject to several high-profile recalls over fire risk. Yet, a new study shows they are less likely to cause a vehicle fire than either gas-powered cars or hybrid vehicles. Analysts from AutoInsuranceEZ examined data from the National Transportation Safety Board to track the number of car fires and compared it to sales data from the Bureau of Transportation Statistics.
The result? Hybrid-powered cars were involved in about 3,475 fires per every 100,000 sold. Gasoline-powered cars, about 1,530. Electric vehicles (EVs) saw just 25 fires per 100,000 sold.
There is some logic to the results. After all, gasoline-powered cars depend on combustion to move. The energy transfer electric cars use to move doesn’t involve anything burning.
....
“Despite the focus on EV fires in the news,” the researchers concluded, “they are not inherently more dangerous than gas or hybrid vehicles, although electric fires tend to be more difficult than gas fires to extinguish.”

Just gossiping here, but, what I found out after I had debadged my (Generation 2) 2018 Leaf was...the badging that said "Zero Emissions" plastered on the sides and back of the car (which I thought was beyond tacky and thus quickly removed them), was there because it was to helpfully "inform" emergency personnel that the car was an ev, not gasoline. So it would be treated differently (foam, I guess, rather than water) to put out a fire.
Again, the Leaf was one of the forerunners in the early days when EVs still were an anomaly....but it must have been a Nissan thing with their Leaf models because Tesla never badged their cars, nor did Chevrolet.
Nissan has since dropped that badging for all their new EVs. No other EV manufacturer out there has ever used any of that badging.
