Power can only be converted to propulsion by the interaction of vehicle components which are perfectly coordinated with each other. With its 5.2-litre V10 FSI engine, the S6 represents superb power delivery across a wide engine speed range and impresses with great comfort over long distances (309 kW/420 bhp; combined fuel consumption: 13.4 l/100 km; combined CO2 emissions: 322 g/km).
