Firefighters were called to a burning Ford Fiesta in Hythe last night.
They attended the scene in North Road in the town following reports that the hatchback was ablaze at 6.45pm.
A Folkestone fire station spokesman said: "It was completely burned out and we're not too sure what the cause was.
"It's a suspected electrical fault."
He added the cause was not suspicious and that it was unlikely to be investigated further.
