Am I missing something it's the Clubsport the sportier version of the standard GTi.
You can blame the EU for that.... the rules changed around Q4 2020 and everything had to be much less noise.
The Mk8 never was loud because of that and things like the BMW M135i suddenly got silenced mid production.
"In 2020, the EU implemented stricter noise emission limits for new vehicles, including cars, vans, and lorries, as part of its broader effort to reduce environmental noise. These new limits, based on Regulation 2014/540, which the UK adopted, initially set a noise limit of 72 decibels (dB). This limit is scheduled to further reduce to 68 dB by 2026"
