Firefighters responded to the blazes from 4:02 to 4:41 a.m. Saturday in a 2.5-mile area north and south of West Berry Street and near Cleburne Road/McCart Avenue.
Investigator Brad Sims said he is confident that the blazes were set.
"We do have it figured out, how they started these fires,” Sims said. “And, yes it’s dangerous to start a fire with something as volatile as a car because of so much fuel involved.”
