What makes it iconic

The lightest A4 in a generation — the B9 used ultra-high-strength steel and aluminum to shed up to 65 kg from its predecessor while growing in size.

History

The B9 A4 introduced Audi's Virtual Cockpit — a fully digital instrument cluster that replaced traditional gauges with a configurable 12.3-inch display. The RS4 Avant returned with a 450-hp biturbo V6.
