In Cars, Lightning McQueen and Doc Hudson had a 1-lap race at Willy's Butte. The agreement in the race was that the loser would fix the road. If Lightning McQueen would win the race, he would get to leave the town free of charges. During the race, Lightning McQueen gets a big lead, without Doc Hudson even leaving the start line until well after the race started. Lightning McQueen was unable to make a sudden turn, and drove down a steep hill, into a pit of cacti. Therefore, Doc won the race and McQueen had to continue to fix the road.
In Cars 2, part of the Radiator Springs Grand Prix at the end of the movie happens in Willy's Butte. The group of World Grand Prix Racers are seen racing at the location, including driving on the curved canyon wall around Willy's Butte that the Radiator Springs residents were spectating from at the top.
