Audi A4/S4 B6

The Audi A4 (B6) was produced from 2000 to 2006 and featured a refined design, improved chassis rigidity, and a range of turbocharged and V6 engines.
The performance-focused Audi S4 (B6) stood out with its 4.2-liter V8 engine, delivering strong acceleration and a distinctive exhaust note.
Both models were praised for their Quattro all-wheel-drive system, high-quality interiors, and balanced blend of comfort and sporty handling.
