The Audi TT is a compact sports car produced by the German automaker Audi since 1998. It is known for its sleek and stylish design, inspired by the 1995 Audi TT quattro concept car. The first generation (1998-2006) was based on the Volkswagen Group's A4 platform, sharing its underpinnings with the Volkswagen Golf Mk4 and Audi A3. The TT's unique design, with its rounded bodywork and pop-up headlights (on early models), quickly became a design icon and contributed to Audi's rising popularity. Initially available in Coupe and Roadster body styles, the first generation TT offered a range of turbocharged four-cylinder petrol engines, delivering a blend of performance and efficiency.

The Audi TT's success was further boosted by its advanced quattro all-wheel drive system, which provided exceptional handling and stability, particularly in challenging conditions. While the TT's exterior design was undeniably striking, its interior offered a driver-focused and sporty environment. The minimalist cockpit featured a driver-oriented layout, with a well-integrated instrument cluster and intuitive controls. Over its production run, the first-generation TT received several updates and revisions, including revised styling, engine upgrades, and the introduction of a six-speed manual transmission. Despite its relatively small size, the Audi TT carved a niche for itself in the sports car market, attracting enthusiasts who appreciated its blend of style, performance, and handling. Today, the first-generation Audi TT remains a popular and collectible vehicle, particularly in well-maintained condition.
