The eighth-generation Audi A6 (internal code C8 / 4K) marks a major technological turning point for Ingolstadt's executive sedan. Launched in 2018 and facelifted in 2023, it stands out with its ultra-modern cabin featuring a dual-touchscreen (MMI Touch Response) and the widespread integration of mild-hybrid (MHEV) technology across almost all its powertrains. Based on the MLB Evo platform, it offers imperial comfort, top-notch sound insulation, and impeccable finish quality. While gasoline engines (TFSI) have gained reliability compared to previous generations (notably the mature 2.0 EA888 unit), this C8 generation is marred by a recurring and costly problem related to its 48V mild-hybrid system (starter-generator) on V6 engines.

The Audi A6 C8 is an impressive technological showcase and an exceptional road car. If you are looking for a gasoline engine, the 2.0 TFSI (45 TFSI) is the most rational and reliable choice: the EA888 unit has now shed its old demons and offers an excellent compromise. However, purchasing a V6 version (55 TFSI or TDI) requires great caution: the 48V starter-generator (BSG) problem is a real financial sword of Damocles if the vehicle is no longer under warranty or if the part has not been replaced by the revised version. Prioritize a model with a clear service history within the Audi network, and do not hesitate to subscribe to an extended warranty for V6 or PHEV models.
