Audi 3.0 TDI CGQ Engine – Overview (2011–2014)
The CGQ engine is a high-performance 3.0-liter V6 BiTDI diesel from Audi’s EA897 family, developed for premium executive models where strong performance and long-distance efficiency are equally important. Producing 230 kW (313 hp), the CGQ features a twin-turbo (BiTDI) setup and advanced common-rail injection, delivering exceptional torque and smooth power delivery across the rev range.
This engine was primarily installed in the Audi A6 (C7) and Audi A7 (4G) platforms between 2011 and 2014, paired almost exclusively with quattro all-wheel drive and Tiptronic automatic transmission. It is well known for its strong mid-range pull, excellent motorway fuel economy for its class, and refined V6 diesel character. Depending on production year and market, the CGQ meets Euro 5 emission standards (with later EA897 evolutions transitioning toward Euro 6).
