Mickey Mouse may have been on a steamboat in one of his first animated shorts back in the 1920s, but his mode of transportation has been upgraded to a roadster in this series. Mickey and his friends participate in high-speed races in their hometown, Hot Dog Hills, and around the world in vehicles that can transform. The familiar names joining Mickey on the track are Minnie Mouse, Goofy, Donald Duck, Daisy Duck and Pluto. Off the track, Minnie and Daisy are busy running a business with which they solve problems for people in need. A number of celebrities -- including real-life race car drivers Jimmie Johnson, Danica Patrick and Jeff Gordon -- lend their voices to the series in guest-starring roles.
