Platform guide · covers 8Y and 8Y (2025 refresh)
Audi S3 8Y
The 8Y S3 is the MQB evo sedan, running the EA888 evo4 2.0T through the DQ381 seven-speed S tronic and Haldex-based quattro. US cars arrived for 2022 as a sedan only, and the 2025 refresh brought real hardware rather than a restyle.

Phases
- 8Y2022 to 2024US sedan only (no Sportback). EA888 evo4, 306 hp, 7-speed S tronic (DQ381), Haldex-based quattro (no rear torque splitter at this phase — that arrives with the facelift).
- 8Y (2025 refresh)2025 to presentAdopts the RS 3's rear torque-splitter Haldex hardware; US rating rises to 328 hp and 310 lb-ft.
Owning and working on it
- Pre-refresh cars are rated 306 hp and 295 lb-ft. The 2025 refresh adopts the RS 3 rear torque-splitter Haldex hardware and lifts the US rating to 328 hp and 310 lb-ft.
- No Sportback for the US. Sedan only.
- The Haldex service is the one owners skip: pull the pump and clean its screen with every fluid change. A clogged screen is how Haldex all-wheel drive quietly dies.
- The evo4 adds port injection alongside direct injection, which slows intake-valve deposit buildup compared with earlier EA888s. Slows, not prevents.
