A teaser trailer for what likely will be the final Disney/Pixar computer-animated comedy will be featured before their latest collaboration, The Incredibles, opening Friday. Hoping to parlay the public’s growing appetite for auto racing, Cars features the voices of track aficionado Paul Newman, who continues to compete at age 79, and NASCAR great Richard Petty. Cars isn’t due in theaters until November 2005, and production won’t finish until next summer. The movie centers on speed-obsessed race car Lightning McQueen (Owen Wilson), who gets lost on his way to the track. He lands in Radiator Springs, a downtrodden town off fabled Route 66 that has been bypassed by the interstate. There, he learns about what really matters from the cars of the 1950s and ’60s.
