Changes

Although the basic idea of the Grand Prix Raceway has not changed since its opening, the name and theming of the attraction have. The first change to the Grand Prix Raceway came in 1973, when the track was expanded<ref name= "Jack"/>. This was followed by a shortening of the track in 1974 as part of the construction of [[Space Mountain]] <ref name= "Lou"/> In 1987 the track was again shortened, this time to make room for Mickey's Birthdayland <ref name= "Jack"/>. In 1996 the attraction was renamed the Tomorrowland Indy Speedway, and it was given new futuristic theming to coincide with the "New Tomorrowland".

In 1999 Disney and the Indianapolis Motor Speedway announced that they would partner together to change the theme of the Tomorrowland Indy Speedway <ref> http://www.wdwmagic.com/attractions/tomorrowland-indy-speedway/news/03nov1999-press-release---tomorrowland-indy-speedway.htm </ref>. Famous items from the Indianapolis Speedway were added to the attraction including:
