Used 2004 Audi S4 Review

Edmunds expert review

Though not quite as enthralling as BMW's frenetic M3, the S4 still offers entertaining performance along with a more livable personality.

What's new for 2004

The all-new S4 sports some serious hardware, not the least of which is a 4.2-liter V8 bristling with 340 horsepower. A convertible body style has been added to the lineup.
