Audi A4/S4 B7

The Audi A4 (B7) was produced from 2004 to 2008 and featured a sharper front-end design, updated suspension, and improved steering compared to the previous generation.
The high-performance Audi S4 (B7) retained the 4.2-liter V8 engine, delivering strong power and a distinctive exhaust sound in both sedan and Avant versions.
Both models were available with Quattro all-wheel drive, refined interiors, and a balance of everyday comfort with sporty driving dynamics.
