Based on the ground-breaking C3 Audi 100, this new model released in 1990 featured a completely new body, featuring the newly adopted corporate Audi face (with the grille integrated into the bonnet) introduced with the Audi V8.

Mechanically, the C4 introduced Audi's first V6 engine - the 90° 2.8 AAH engine capable of producing 128kW.
