The Audi A2 (internally designated Typ 8Z) is a compact MPV-styled supermini car produced by the German manufacturer Audi from November 1999 (for the 2000 model year) to August 2005. It is a five-door hatchback with four or five seats. Based on the Audi Al2 concept car first shown at the Frankfurt Motor Show in 1997, the A2 was notable for being constructed from aluminium, which made it lightweight and alongside its efficient engines made it highly fuel efficient.
