Radiator Springs Racers Attraction based on the movie Cars in Cars Land at Disney California Adventure, opened on June 15, 2012. A leisurely, scenic tour of Ornament Valley turns into an all-out race for the Piston Cup as guests race through the mountain range, around Willy’s Butte, and past Radiator Falls. Along the way, there is a stop at either Luigi’s Casa Della Tires or Ramone’s House of Body Art. The six-passenger ride vehicles come in eight colors, each with its own personality. At almost six acres, the attraction is the largest by acreage at the Disneyland Resort.
