Four electric Amazon delivery vans were destroyed by fire early Monday at a Rivian dealership in Southwest Portland.
Firefighters responded to a report of trees on fire and found four of the vans were burning.
Batteries in electric vehicles burn extremely hot, and once they start burning they either have to be drowned with water or allowed to burn out. Firefighters let them burn, and kept the flames from spreading.
No one was injured in the fire.
Investigators say it was arson and they're asking anyone with information about the fire to contact them.
