Al Oft is a recurring character in the Cars series, and he is a blimp that works for the Piston Cup racing series. He soars high above the sky during Piston Cup races, advertising for Lightyear, the official tire brand of the Piston Cup.
"Al is high on life. As an endorsement billboard in the sky for the Lightyear Tire company (proud sponsor of the Piston Cup), he loves to provide those grand images high above the track. He's just happy that his job sends him to great sporting events, because he always has the best seat in the house!"
Al Oft is an allusion to the classic "Goodyear" blimps seen at many sports events. Instead of the traditional "Goodyear" logo branded across its side, Al's logo says "Lightyear." This is a reference to Buzz Lightyear from Toy Story.
