NASCAR and Chevrolet are investigating a fire inside the pace car during Saturday night's exhibition race at Daytona International Speedway.
Black smoke began billowing from the Chevrolet SS right before the third segment of the Sprint Unlimited race.
Flames could be seen shooting from the rear of the car as it sat on the apron and two NASCAR officials jumped out.
A spokeswoman for Chevrolet said the manufacturer was working with NASCAR to determine what caused the fire, although an auxiliary battery pack which powers the race lights is thought to be the cause of the inferno.The Chevrolet SS is made in Australia by Holden and is essentially a replica of the Commodore, with Chevy badges and trimmings.
