[Source] The Motor Speedway of the South is a racing speedway that appears in the 2006 Disney/Pixar feature film Cars. Located in Nashville, Tennessee, United States, it is where a supposed three-way battle for the Piston Cup is being held, as The King, Chick Hicks and Lightning McQueen cross the finish line at the same time, and race officials decide that the three racers will compete in one final race at the Los Angeles International Speedway to determine who will win the Piston Cup.
