📚 Vehicle History

Audi Legacy:

Audi's reputation for engineering excellence, particularly with the development of turbocharged engines and Quattro all-wheel drive systems.

C3 Generation:

The C3 generation (Typ 445) of the Audi 100/200 was introduced in 1982 (as the Audi 100) and the 200 followed. This generation saw significant aerodynamic improvements and the widespread introduction of Quattro.

Facelift:

The years 1989-1991 represent the later part of the C3's lifecycle, which received updates including revised exterior trim, improved interior features, and potentially minor powertrain enhancements. The 100 was replaced by the Audi A6 (C4) in 1994.

Manufacturing Location:

Germany (primarily Ingolstadt)

🏆 Awards & Recognition

Automotive Press:

Consistently praised by automotive press of its time for its aerodynamic design, refined ride, and the groundbreaking Quattro system.

Design Awards:

The C3 generation's aerodynamic coefficient of drag (Cd) was among the best in the world upon its introduction, contributing to its efficient operation and quiet cabin.
