The Audi TT is an automobile produced by Audi in Győr, Hungary. The TT was first shown as a concept car at the 1995 Frankfurt Motor Show. The design is credited to J Mays and Freeman Thomas of Volkswagen’s California design studio. The name is an abbreviation of "Tourist Trophy", not "Twin Turbo" as is often assumed. The production model was launched as a coupé in September 1998, followed by a roadster in August 1999, based on the Volkswagen A platform used for the Volkswagen Golf and the Skoda Octavia.
