Note: The Audi A6 (Type 4A-C4) was manufactured in Europe from 1994-1997 and in China from 1998-2003. History The factory designation "4A - C4" for the fourth generation of this series was continued to be used on the Audi A6, as it is not considered as a new model, but a facelift of the Audi 100 C4. The basic technical layout is identical to the previous model. Like its predecessor models, the A6 C4 has the fully galvanized body introduced in 1985. It is equipped with four, five, six and eight-cylinder engines. The Quattro all-wheel drive system is also available as an option in selected engine and equipment variants. The most noticeable change compared to its predecessor, the Audi 100 C4, besides the facelift, is the introduction of the most powerful diesel Audi engine for its time. It is an in-line five-cylinder with direct injection, distributor injection pump, turbocharging (bypass turbocharger), air mass meter, electronically controlled exhaust gas recirculation and exhaust gas cleaning using a catalytic converter. This unit has an output of 103 kW (140 PS) and is technically a modified version of the 84 kW engine from the Audi 100. This diesel engine allows Audi to exceeds the 200 km / h mark for the first time. This engine is available with an automatic transmission or, for the first time, a manual transmission with six gears on a diesel vehicle. This diesel engine was also available for the Quattro version.

Side strips on the doors / fenders that are also in the same color as the exterior paintwork. They make a strong visual effect and give the vehicle a completely new, modern look. In addition, the front and rear have been revised and visually adapted to the new Audi line-up of A4 and A8 models, which were also introduced in 1994. The right wing mirror is now slightly smaller than the left, this reduces the frontal area (and indirectly the drag coefficient). In addition, many of the simpler model versions already have equipment details that were previously only offered in the higher versions of the Audi 100. As with the A4 and A8, the odometer and trip meter are now made using LCD technology. A higher quality version of the plastic surfaces of the interior creates [...]
