Audi A6 C4 (1994-1997): How to Remove Bumpers

When discussing cars that left their mark on automotive history, the Audi A6 C4 certainly deserves mention. This generation served as a transitional link between the classic Audi 100 sedans and modern A6 models. The vehicle turned out to be solid, technologically advanced, and yet full of character. Let's examine what made this model memorable.

Generation and Internal Designation

Audi A6 C4 is an unofficial name, as the model originally continued the Audi 100 line. However, in 1994 the company decided to rename its flagship sedan as the A6 to standardize nomenclature (following the A4 and A8 pattern). The internal factory designation is Typ 4A, with body variants including:

• Sedan (traditional four-door)

• Station wagon (Audi 100 Avant, later A6 Avant)

Production Years and Facelift

The C4 generation debuted in 1991 as the Audi 100, receiving a facelift and name change to A6 in 1994. Production continued until 1997 when it was replaced by the more rounded C5.

The 1994 facelift introduced:

• New radiator grille (wider, in Audi A8 style)

• Revised headlights (with clear sections instead of orange)

• Updated dashboard

• Upgraded engines

Gasoline:

• 1.8 (125 HP) - base model, underpowered for weight

• 2.0 (115-140 HP) - reliable but sluggish

• 2.3 (133 HP) - distinctive-sounding five-cylinder

• 2.8 V6 (174 HP) - popular balanced option

Diesel:

• 1.9 TDI (90-110 HP) - economical and nearly indestructible

Model Description

The A6 C4 embodies classic executive styling with elegant yet restrained lines. The spacious interior uses quality materials, though the design is typical 1990s: angular shapes, analog gauges, minimal electronics.

The suspension prioritizes comfort with predictable handling rather than sportiness. Safety features were advanced for the era: ABS, airbags, rigid body structure. Top trims included automatic climate control and cruise control.

Interesting Facts:

• Last "boxy" Audi design - subsequent models became more rounded

• Secret prototype: Hybrid A6 Avant Duo (electric + gasoline)

• Long production in China: Continued until 1999 as Hongqi CA7220

• Movie star: Appeared in German crime series "Tatort"

Conclusion

The Audi A6 C4 combines robustness, reliability and 1990s character. While not as iconic as the Mercedes W124 or BMW E34, it deserves recognition as one of the last "honest" executive cars. A well-maintained V6 or TDI model offers classic motoring without unnecessary electronics.
