The second generation of the Audi A4 was revealed in October 2000 while the station-wagon version came-up in 2001.
In the traditional Audi’s naming, that version was called Avant.

The Audi march toward the premium station-wagon market was continued with the second generation of the A4 Avant. It started with the same body up to the B-pillar and then it changed everything. The straight roof went up above the trunk space and went downward in a slope angle. Like any Avant version before, the Audi doesn’t like vertical tailgates.

For the interior, the Audi Avant featured started with a basic audio system but an optional, more complex, system that was offered. That had a navigation unit and even a telephone attached to it. It also has Bluetooth connectivity. For the rear seat, the extended roof was a blessing, giving more headroom for the back-seat passengers. The trunk was not the biggest
in its class but still was good enough for most of the time.

For the technical department, Audi threw everything into battle against its main rivals, BMW and Mercedes-Benz. At the time of launch, the base engine was a 1.8-liter unit but a 1.6-liter was added later. The offer went up to the mighty 4.2-liter V8 engine on the Audi RS4 Avant. For the diesel units, it started with a 1.9-liter TDI (direct-injected turbodiesel) and went up to a 2.5 TDI unit.
