In 1989 and 1990, Hendrick Motorsports served as a technical consultant during the filming of "Days of Thunder", including providing camera-equipped race cars to capture racing footage. The team prepared 14 race cars for the filming. In-race footage was taken at the 1989 Autoworks 500 at Phoenix International Raceway, and the 1990 Daytona 500, in addition to stunt footage shot outside of NASCAR events. At each race, the cars would run 100 miles before start-and-parking. At Phoenix, Hendrick qualified two movie cars: the No. 46 City Chevrolet Lumina driven by Greg Sacks, and the No. 51 Exxon Lumina driven by Bobby Hamilton. An additional car, the No. 18 Hardee's Lumina driven by Tommy Ellis, failed to qualify. Though the cars were not intended to run competitively, Hamilton qualified fifth and led five laps before pulling off the track. Sacks would run the 46 in the Busch Clash exhibition race at Daytona in early 1990, finishing second in one of the movie cars. After the incident at Phoenix, the two cars fielded at the Daytona 500 with Ellis (No. 18 Hardee's Lumina) and Hamilton (No. 51 Mello Yello Lumina) were not officially scored.
