The RS4 Avant was built by Quattro GMbh and was a 380 hp beast, with a 2.7-liter V6. It was unveiled for the public in 2000 and its production only last 2 years, until 2002. The model was built as an estate/wagon body only, no coupes and sedans were available.

The RS4 was much like the regular Audi A4 Avant, however, the technical features differenced the two a lot.

The car sproted 18-inch alloy wheels with extremely efficient ventilated discs. The car came from 100 kph to a full stop in just 2.5 seconds. The power was transmitted to the road by the all-wheel-drive permanent system and a 6-speed manual gearbox.
The RS4 had a maximum top speed of 250 kph and reached 100 kph in 4.9 seconds.

The interior was different from the A4 due to its sporty Recaro Seats all wrapped up in leather. Other features included a 3-spoke steering wheel and a 170 watt Bose sound system.

Even if the RS4 was a car that shamed a Porsche 911, it was practical as well. It had 390 liters of loadspace and 1250 liters with the rear seats folded.

The safety equipment of the RS4 included dual front airbags, front side airbags, ABS, electronic brake force distribution, ESC and traction control.
