Mack carries Lightning McQueen to the Piston Cup race in Pixar’s Cars.
Mack is Lightning’s large red transport truck and one of his racing-team vehicles. After Lightning competes in the Dinoco 400, the team prepares to travel to California for the Piston Cup tiebreaker. Mack is responsible for transporting Lightning and the team’s equipment, but exhaustion causes him to stop and fall asleep during the journey.
Lightning leaves the truck while Mack is distracted, which begins the chain of events that brings Lightning to Radiator Springs. The mistake separates him from the racing team and ultimately changes his attitude toward competition and friendship. Mack is voiced by John Ratzenberger, a performer associated with many Pixar films. Mater is a tow truck from Radiator Springs, while Sarge and Fillmore are local residents, so none of them performs Mack’s transport role.
