    Audi adopted the letter S directly from the world of motor sport. In 1985, it appeared on a competition car from the World Rally Championship – the legendary S1. The Coupé, the last evolution stage of the Sport quattro, was a high-tech unit driven to the outer limits, which mustered up around 370 kW (approx. 500 hp) of power for its drivers.

    In 1990 the letter S made its way into series production – in the S2 Coupë, whose turbocharged five-cylinder engine delivered 162 kW (220 hp). The small S family grew rapidly; its members had quattro drive and a visually understated appearance in common. At the end of 1992, Audi added an S2 Avant; one year later the sedan followed. 9,488 units of these three body variants were built up until 1995.

    The first Audi A4, which was launched in 1994, also generated two S models, starting in 1997. The five-cylinder turbo made way for a newly developed twin-turbo V6; the 2.7-liter was derived from the V8 with a displacement of 3.6 liters. With five-valve cylinder heads and one turbocharger per cylinder bank it produced 195 kW (265 hp) and 400 Nm (295.02 lb-ft) of torque, which was available from as low as 1,850 rpm. Produced up until 2001, some 30,500 units of the first-generation S4 were built.

    At the beginning of 2003 Audi switched its S models in the midsize class to naturally aspirated engines. The 4.2-liter V8 developed 253 kW (344 hp) and delivered 410 Nm (302.40 lb-ft) to the crankshaft at 3,500 rpm. The V8, which could also be combined with a six-speed-tiptronic, was introduced in the sedan, the Avant and the Cabriolet. Up until the model change, more than 38,000 units had come off the assembly line.
