Audi’s compact executive saloon, launched in 1994 to replace the Audi 80 and retired in 2025 in favour of a saloon sold under the A5 name instead.[1] Markey covers the nameplate’s first and last generations: the B5 of 1994, which set the template of a chrome single-frame grille, front-drive base cars and quattro further up the range that every A4 since has followed; and the B9 of 2015, the final car built before Audi folded even-numbered saloon nameplates into its odd-numbered coupé line. The three generations between them (B6, B7 and B8) are not yet catalogued here.
