Audi 100 C4 – The Fourth Generation of the Legendary German Model

The Audi 100 C4 is the fourth generation of the legendary German model, which became an important milestone in the evolution of the brand. This car was produced from 1990 to 1994, and in some countries until 1997. The internal factory designation is Typ 4A, but among fans of the brand, it is better known as the C4.

Body Types and Modifications

The Audi 100 C4 was offered in several body styles:

• Sedan – the classic four-door version.

• Avant – a five-door station wagon, which first appeared in this generation. Before this, the Audi 100 was only available as a sedan.

• Audi S4 (from 1992) – a luxury sports version that later became the S6 after the model name was changed.

Technical Features and Engines

The fourth generation of the Audi 100 was a true technological breakthrough:

• Aerodynamics – a drag coefficient (Cx) of just 0.29, which was an outstanding figure for the early 1990s.

• Front-wheel or all-wheel drive – depending on the modification. All-wheel-drive versions were equipped with the quattro system.

• Engines – the lineup included gasoline and diesel engines:

  • 2.0 L (115 hp)

  • 2.3 L (133 hp)

  • 2.8 L V6 (174 hp) – one of the most powerful in the range.

  • Diesel engines – 1.9 TDI (90 hp) and 2.5 TDI (140 hp), known for their reliability.
