Rockwell Automation is the primary sponsor of #20 Joe Gibbs Racing Chevrolet in the NASCAR Busch Series driven by Denny Hamlin and Aric Almirola. In 2006, Rockwell Automation made two trips to victory lane in NASCAR's Busch Series at the inaugural race in Mexico City and at the spring race in Darlington. In 2007, Rockwell Automation again won the spring race in Darlington, the AT&T 250 at the Milwaukee Mile, and the Carfax 250 at the Michigan International Speedway in August of 2007. The Milwaukee win was not without some controversey as Almirola qualified the car and started the race, but was forced to get out of the car (while leading) by Joe Gibbs Racing , so Nextel Cup superstar Denny Hamlin could drive to the victory. This happened because Denny Hamlin, originally scheduled to drive the entire race, arrived late because his helicopter had no place to land. While the Joe Gibbs team was extremely happy with Almirola's driving, it is believed that they felt they owed it to Rockwell to put Hamlin in the car, since the race was at Rockwell's "home track."
