McDonald's released Happy Meal toys of eight of the Cars characters, some of which come in variations. They were available in North America from June 9 through July 6 in the United States and Canada, and they were also available in Japan.
- Lightning McQueen (clean and dirty)
- Doc Hudson
- Ramone (purple, green and yellow)
- In Cars, Fillmore was originally going to be called "Waldmire," named after Robert "Bob" Waldmire, a Route 66 resident whom the crew befriended during their road trip to do research for the film. However, Waldmire was vegan, and he did not want his name to be featured in Happy Meal toys at McDonald's.
- McDonald's is the first restaurant to have promoted a Cars film. Subway would later promote Cars 3 in 2017.
