About the Audi S4 B7
The B7-generation Audi S4 is a masterclass in subtlety, retaining the 4.2-litre V8 from its B6 predecessor while adopting the updated 'Singleframe' grille design. Unlike the high-revving RS4 that followed, the S4 focuses on effortless torque and daily usability, paired with Audi's signature Quattro all-wheel-drive system. It remains a favourite for collectors who appreciate the 'sleeper' aesthetic, though potential owners must be wary of the well-documented timing chain guide issues. The combination of a compact chassis and a large-displacement V8 provides a driving character that is increasingly rare in the modern era.
