Harv is Lightning McQueen's agent. Never seen on-screen, McQueen speaks to Harv via his speaker phone when McQueen and Mack are on route to the tiebreaker race and again when Mack is in Radiator Springs to pick up McQueen. Consequently, little is known of Harv's character except that he would fire Mack if he didn't get McQueen in Mack's trailer.
