Audi introduced the fifth generation of the A4 lineup in 2015 and refreshed it in 2019 for the 2020 model year, and that update affected the entire range, including the TDI version of the S4 Avant.

AUDI S4 Avant

The ninth generation of the A4 was introduced in 2008 and was based on the same platform as its predecessor, although with some aesthetic changes.

The fifth generation of the sporty S4 saw the lights of day in late 2008, and the Avant version wasn't sold on the North American market, leaving its fans in tears.

In 2005, Audi introduced the new generation of the S4. It was available as a sedan, convertible and station-wagon, named Avant. It was a true factory sleeper.

Introduced in 2003 as a sedan and a station wagon, the S4 represented the third generation of the performance-oriented version of the A4 lineup, and, unlike its main competitors, it was all-wheel drive.

The Audi S4 (or the Audi B5) was very similar to the A4 model, however, it had a lower suspension, beautiful 17-inch wheel, chrome accents, and a color coated grille with a sporty feel.
