Cars was later followed by a sequel in 2011, Cars 2. In the sequel, Lightning gets invited to a racing competition called the World Grand Prix, which takes him and Mater on a trip around the world. However, while in Tokyo, secret agents Finn McMissile and Holley Shiftwell mistake Mater for an American spy and get him involved in trying to figure out who is behind all the engine blowouts occurring in the race.
A second sequel, Cars 3, will be released in 2017.
In 2006, Cars toys were featured as toys in McDonald's Happy Meals, some of which come in different variants. This included Lightning McQueen (in clean and dirty forms), Mater, Sally Carrera, Doc Hudson, Ramone (in purple, green and yellow paint jobs), Flo, Luigi and Fillmore.
The character Fillmore was originally going to be named Waldmire, named after Route 66 resident Robert "Bob" Waldmire whom the film's crew befriended during a trip on Route 66. However, Waldmire was a vegan and since Cars toys were going to be featured at McDonald's, he refused to let them use his name.
