AudiTT RS
The Audi TT is a sports car manufactured and marketed by Audi from 1998 to 2023 across three generations. Its bodystyles included a coupé with a 2+2 seating arrangement and a two-seater roadster. For each of its three generations, the TT has been based on consecutive generations of Volkswagen's "Group A" platforms, starting with its "PQ34" fourth generation. The TT shared powertrain and suspension layouts with other models made on these platforms, including the Audi A3, like a transversely mounted front-engine, powering front-wheel drive or four-wheel drive, and fully independent suspension using MacPherson struts in the front.

Dates with their meaning intact
Model years in Natural Resources Canada retail fuel-consumption data; Canadian-market evidence, not a worldwide production range.
First-admission years observed in Dutch vehicle registrations; this is market evidence, not a worldwide production range.
Swiss type-approval years; approval dates are not production chronology.
This record contains useful sourced evidence, but it does not yet meet the reference-ready standard. Still needed: production chronology. Fields we cannot source stay empty rather than guessed.
High-performance TT flagship, reviving Audi's turbocharged inline-5 layout. First generation (8J, 2009-2014) made 340-360 PS; second generation (8S/FV, 2016-2023) made 400 PS. Built at Audi's Gyor, Hungary plant. Note: a separate DVLA-sourced catalog record 'TTRS' (id audi-ttrs-2016-dvla) likely represents the same real car under a different naming convention — not merged here since normalize_model_key() doesn't treat 'TT RS' and 'TTRS' as equivalent (differ by a literal missing space, not a substitutable separator); worth a manual dedup pass in the future.
