A uniquely colored white and red 1969 Camaro RS/SS 396 convertible was used as the pace car for the Atlanta 500 NASCAR Grand National event held at the Atlanta International Raceway (now Atlanta Motor Speedway) in Hampton, Georgia on Sunday, March 30, 1969. Cale Yarborough won the race in his Wood Brothers 1969 Mercury.
The first three pictures came from the Internet Movie Cars Database. The Camaro pace car appears briefly in a movie released in 1977 entitled "Greased Lighting." The movie is about the true life story of Wendell Scott who was the first African American stock car racing driver to win an upper tier NASCAR race and it starred Richard Pryor and Beau Bridges. The Camaro pace car appears briefly in the last third of the movie when actual archival race footage from the 1969 Atlanta 500 was inter-spliced with other racing footage to help demonstrate the career of Wendell Scott.
The fourth picture shows the Atlanta Camaro pace car on the parade lap at the North Carolina Motor Speedway prior to the Carolina 500 NASCAR Grand National event held three weeks before on Sunday, March 9, 1969. Notice that the Camaro was equipped with a roll bar after it's appearance for it's pacing duties. It does not appear in the pictures taken at North Carolina Motor Speedway but it does at Atlanta International Raceway.
