Chevrolet working with NASCAR to determine cause of fire in pace car during race at Daytona

DAYTONA BEACH, Fla. – 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 replacement pace car was brought out to finish the race.

A spokeswoman for Chevrolet said the manufacturer was working with NASCAR to determine what caused the fire.

General Motors earlier this week recalled almost 800,000 of its 2005-2007 Chevrolet Cobalt and 2007 Pontiac G5 compacts in North America because of faulty ignition switches.

And, a sinkhole at the National Corvette Museum in Kentucky swallowed eight rare cars.
