Police were also at the scene in Leegomery after the alarm was raised just after midnight on Wednesday when a car in Chockley's Meadow went up in flames.
Two fire crews from Wellington were dispatched along with a Fire Investigation officer.
Shropshire Fire and Rescue Service said firefighters wore breathing apparatus to fight the fire which had spread to a second vehicle.
It was extinguished in 50 minutes with a thermal imaging camera used to ensure the blaze was completely out.
It is not yet known if the fire was deliberate.
This year has seen a spate of car fires across Telford since December, including six in 10 days, with police comfirming many have been arson attacks.
One of the car fires involved a car belonging to far-right activist Tommy Robinson, whose real name is Stephen Yaxley-Lennon, which was set on fire outside Wellington's Whitehouse Hotel in January.
Police said that attack was not linked to any of the other blazes.
