The production model Audi TT (Type 8N) was launched as a coupé in September 1998, followed by a roadster in August 1999. It is based on the Volkswagen Group A4 (PQ34) platform as used for the Volkswagen Golf Mk4, the original Audi A3, the Škoda Octavia, and others. The styling differed little from the concept, except for slightly reprofiled bumpers, and the addition of rear quarterlight windows behind the doors. Factory production commenced in October 1998.
