The Audi allroad quattro began in 1999 as a semi-offroad version of the Audi A6 Avant. Since 2009, Audi has also offered the "Audi A4 allroad quattro", based on the mainstream Audi A4 Avant (wagon). Audi accordingly retitled subsequent generations of the larger allroad, as released in 2006 and 2012, as "Audi A6 allroad quattro".
