The Audi A6 is an E-segment passenger car produced by the German manufacturer Audi, now in its fifth generation. As the successor to the Audi 100, the A6 is manufactured in Neckarsulm, Germany, although some were built in China for later commercialization. It is available in sedan and estate configurations, the latter marketed by Audi as the Avant. Audi’s internal numbering treats the A6 as a continuation of the Audi 100 lineage, with the initial A6 being designated as a member of the C4 series, followed by the C5, C6, C7 and C8. The related Audi A7 is essentially a fastback version of the C7 and C8 series of the A6, but marketed under its own separate identity and model designation.

All generations of the A6 have offered either front-wheel drive or Torsen-based all-wheel drive, marketed by Audi as its quattro system. The second and third generation A6 models have shared their platform with the company’s Allroad models.

Both diesel and gasoline versions of the A6 are offered. The wide range of available engines range from 150 to 333 PS. These are turbocharged 16-valve in-line four-cylinder engines and more powerful three-liter units in V6 configuration with mechanical compressor.


Audi A6 C4 (1994-1997)

Audi’s E-segment car was called the Audi 100 and was released in three successive generations (Audi C1, Audi C2 and Audi C3) .1 In 1994, the last generation (C4) of the Audi 100 received a restyling and was renamed as Audi A6 to adapt to the new Audi alphanumeric nomenclature (as the Audi A8 F segment had just been introduced). The exterior was slightly modified from the Audi 100 “C4”, new headlights and taillights, new radiator grille, as well as chassis, engine and transmission options. The UK was the first market to receive the A6, as the right-hand drive Audi 100s sold out earlier than expected, earlier than the rest of continental Europe.

The new engines for the A6 were a 1.8-liter 20v inline four-cylinder, a 2.0-liter 8v inline four, a 2.6-liter 12v V6 and a 2.8-liter 30v V6, with the 2.3-liter inline five-cylinder being abandoned in most markets. For diesel engines, a 1.9 Turbo direct injection (TDI) four-cylinder in-line and a 2.5 TDI five-cylinder in-line (R5) of 140 PS were available

Until 1997, the A6 came with several different engines, two of them turbodiesel, and most of them available with Audi’s Torsen-based quattro permanent all-wheel drive system. The A6 was available with sedan and Avant bodywork.
