Audi is a German automotive manufacturer founded in 1910. Audi existed independently until 1932, when it merged with Horch, DKW, and Wanderer to form Auto Union. Auto Union suffered greatly due to WW2, being forced to relocate, and relaunch as a spare parts company. The company struggled and was completely taken over by Volkswagen in 1966. Audi would soon launch the Audi 100, whose success allowed for the company to grow and establish itself as a major player in the German luxury car market. Through its years, Audi has participated often in motorsport, giving the company performance pedigree as well as luxury pedigree. This lead to the creation of some highly regarded models like the Quattro, RS2, TT, and R8. Audi is also well known for their A4, A6, and A8 sedans, which have spawned their respective 'S' and 'RS' performance models.
