Updated July 30, 20261 min readCited sources

The Audi A4 was a line of compact executive cars produced by Audi from 1994 to 2025, offered mainly as a sedan and wagon. It was one of Audi’s core premium models before being replaced by the A5 in the lineup for the 2025 model year.

What it is

The Audi A4 debuted in 1994 as the successor to the Audi 80, and became Audi’s compact premium sedan. It was sold in sedan and wagon (Avant) body styles through five generations, using front-wheel drive or Quattro all-wheel drive on many versions.

Key details

Early A4s used Volkswagen Group B platform variants, while the fifth generation moved to the MLB Evo architecture. Recent U.S. and Canadian models featured a 2.0-litre turbocharged four-cylinder with a 48-volt mild-hybrid system, and Quattro all-wheel drive was standard on many trims.

Final years and replacement

In its final model years, the A4 lineup was simplified, with the 45 TFSI variant becoming the main offering. Audi’s model-family material indicates the A4 was replaced by the A5 in 2024, ending a 31-year production run in the compact executive segment.
