The third generation Audi 100, launched in September 1982, had an aerodynamic look, achieving a drag coefficient of 0.30 for its smoothest base model. The two-door models were no longer available, and the Audi 100 Avant was now positioned as a station wagon rather than a hatchback - the Avant designation would now be used for all Audi station wagons from that point forward. The 200, launched in 1983 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 Audi 100 also featured a 2.5 L straight-five direct injection turbo-diesel (TDI) model with 120 PS (88 kW) introduced in January 1990 (engine code 1T). This was the first model to wear the TDI label. It had a brief career in the C3, being replaced in December of that year when the C4 arrived.
