From `2011` to `2015`, the facelifted `S4 Avant B8` represents the best balance of this generation for many buyers: a cleaner design, a cabin that feels more resolved and the same fast-estate recipe built around the supercharged `3.0 TFSI`. Against a BMW 3 Series, it is less theatrical than a sporty rear-wheel-drive car, but deeply convincing through traction, versatility and its ability to cover ground all year round. Used, it naturally attracts buyers who want a modern `S4` without moving into later phases that depend even more on software.
