AUDI

AUDI AG, (Xetra: NSU), commonly known as Audi, is a premium luxury German automobile manufacturer which produces Audi branded cars, with headquarters in Ingolstadt, Bavaria. Audi has been an almost wholly-owned (99.7%) subsidiary of the Volkswagen Group (Volkswagen AG) since 1964 (when the group was formerly known as "Volkswagen Audi Group" - VAG), and is held in ownership by its shareholders – hence the term "Aktiengesellschaft" or "AG". The company evolved from Volkswagen Group's takeover of both Auto Union, and NSU Motorenwerke AG (NSU), the former having incorporated the historic Audi company which was founded in 1910.
The Audi S5 was released to the public at the same time as the A5. The S5 is powered by a 4.2L Fuel Stratified Injection (FSI) V8 engine, producing 354 PS (349 hp/260 kW). It has a more aggressive fascia (as do most Audi S and RS models), including a string of LED daytime running lights around the high-intensity discharge lamp (HID) headlamps (although these are available as an extra on the standard A5).
