From Blu-Ray Guide: With over 90 wins and seven championship titles to his name, Formula One racer Michael Schumacher is one of the most celebrated racecars ever. Born into humble origins, he grew up on the local short track his father maintained, and developed the skills he would need to become one of the most accomplished athletes in the world. Making his way up the ranks of the European road racing leagues, he went on to achieve a racing career so successful that his record will most likely never be surpassed. But when it comes down to it, there's nothing Michael loves more than spending time with his loving family.
Near the end of the film, Michael shows up at Luigi's Casa Della Tires at the recommendation of Lightning McQueen. He is accompanied by a pair of Maseratis who are named Costanzo Della Corsa and Antonio Veloce Eccellente. He also appears at the Grand Re-opening of the Wheel Well Motel.
