The Audi 100 was a mid-sized automobile manufactured from 1968–1994.
The two-door models were no longer available, and the Audi 100 Avant was reintroduced as Audi's first attempt at a station wagon based on the 100. The 200 continued as the upmarket variant with several versions of the 2.2 L turbo 5-cylinder available in different markets over its life ranging in power outputs from 165 PS (121 kW) MC engine, through the 200 PS (147 kW) versions to the final 220 PS (162 kW) 20-valve 3B engine available from 1991. The 200 20V was distinguished by its flared front and rounded rear wheel arches instead of the flat type used for the rest of the 100-200 range. The MC turbo engine was available in the 100 as well for some markets.
The 100 also featured a 2.5 L straight-5 direct injection turbo-diesel (TDI) model with 120 PS (88 kW) introduced in 1990 (engine code 1T). A such-engined Audi 100 was the very first model to wear the now ubiquitous and hugely successful TDI label that changed the perception of diesel engines all over the world.
