===Model introductions===
In the mid-to-late 1990s, Audi introduced new technologies including the use of aluminium construction. Produced from 1999 to 2005, the [[Audi A2]] was a futuristic super mini, born from the Al2 concept, with many features that helped regain consumer confidence, like the aluminium [[space frame]], which was a first in production car design. In the A2 Audi further expanded their TDI technology through the use of frugal three-cylinder engines. The A2 was extremely aerodynamic and was designed around a [[wind tunnel]]. The Audi A2 was criticised for its high price and was never really a sales success but it planted Audi as a cutting-edge manufacturer. The model, a [[Mercedes-Benz A-Class#W168|Mercedes-Benz A-Class]] competitor, sold relatively well in Europe. However, the A2 was discontinued in 2005 and Audi decided not to develop an immediate replacement.

The next major model change came in 1995 when the [[Audi A4]] replaced the [[Audi 80]]. The new nomenclature scheme was applied to the Audi 100 to become the [[Audi A6]] (with a minor facelift). This also meant the S4 became the [[Audi S6|S6]] and a new S4 was introduced in the A4 body. The S2 was discontinued. The [[Audi Cabriolet]] continued on (based on the Audi 80 platform) until 1999, gaining the engine upgrades along the way. A new [[Audi A3|A3]] [[hatchback]] model (sharing the [[Volkswagen Golf Mk4]]'s platform) was introduced to the range in 1996, and the radical [[Audi TT]] [[coupé]] and [[Roadster (automobile)|roadster]] were debuted in 1998 based on the same underpinnings.

The petrol engines available throughout the range were now a 1.4&nbsp;L, 1.6&nbsp;L and 1.8&nbsp;L four-cylinder, 1.8&nbsp;L four-cylinder turbo, 2.6&nbsp;L and 2.8&nbsp;L [[V6 engine|V6]], 2.2&nbsp;L turbo-charged five-cylinder and the 4.2&nbsp;L [[V8 engine]]. The V6s were replaced by new 2.4&nbsp;L and 2.8&nbsp;L 30V V6s in 1998, with marked improvement in power, torque and smoothness. Further engines were added along the way, including a 3.7&nbsp;L V8 and 6.0&nbsp;L [[W12 engine]] for the A8.
