The RS models
The RS models have been at the top of the Audi range since 1994. In the upper midsize class, the RS 2 and RS 4 defined the standards in terms of power and performance, in the full-size class the RS 6 advanced into a new dimension. All RS models combine emotion and perfection to form a fascinating overall concept.
The Audi RS 2 was the result of a cooperation with Porsche in 1994. Its five-cylinder turbocharged engine with four-valve technology generated an output of 232 kW (315 hp), which the quattro drive transformed superbly into forward propulsion. Its performance placed it in the league of powerful sports cars, as did its brake system. With the RS 2, Audi created a concept that was picked up and continued by the first Audi RS 4 in 2000. This was powered by a 2.7-liter V6 engine with twin turbochargers, generating 279 kW (380 hp).
The Audi RS 4 presented in 2005 followed another technical path – using a naturally aspirated, high-revving V8 engine. FSI gasoline direct injection enabled the 4.2-liter engine to generate 309 kW (420 hp). Its torque was 430 Nm (317.15 lb-ft) at 5,500 rpm. The RS 4 was available as a sedan, Avant and convertible. Its predecessors had only been available as Avant models.
In the A6 model series, the Audi RS 6 made its debut in 2002. This model was powered by an early version of the 4.2-liter V8. Charged up with two turbochargers, the five-cylinder engine with manifold fuel injection generated 331 kW (450 hp). Audi offered the first RS 6 as a sedan and as an Avant. The pinnacle of the model range was the special limited edition RS 6 plus with 353 kW (480 hp).
