The Audi A6 is an executive car made by the German automaker Audi. All generations of the A6 have offered either front-wheel-drive or Torsen-based four-wheel-drive, marketed by Audi as their quattro system. The A6 has also been used as the basis for the company's Allroad models since 1999.
Both petrol and diesel versions of the A6 are offered. The wide range of engines available have power outputs ranging from 150 to 333 PS (110 to 245 kW). These are inline four-cylinder turbocharged engines and more powerful 3-litre units in a V6 configuration with a mechanical compressor.
The fourth generation C7 series Audi A6 (internally designated Typ 4G) was launched in early 2011 for the European market and in other markets soon after. It is heavily influenced by the Audi A8 (D4), pulling elements from its exterior details.
The A6 shares its interior, platform, and powertrain (Modular Longitudinal Platform) with the Audi A7 four door sedan, which had been released shortly before also in 2011. Compared to the A8 and A7, the A6 has the most aggressive front fascia and LED headlights (optional full LED headlamps). Design work began in 2006, with Jurgen Loffler's exterior design being chosen in 2008.
