The Audi A4 is a compact luxury car marketed since 1995 in four generations which are named after the Volkswagen Group platforms the cars were constructed on. They were B5 (1994-2001), B6 (2000-2006), B7 (2004-2008) and B8 (since 2008). A four-door sedan was released first and a five-door station wagon (Avant) hit the market a year later. In 2002, Audi started producing a two-door convertible which lasted through the second (B6) and the third (B7) generations, up to 2009. Throughout its lifespan, the A4 tried on a number of engines, the smallest of which was a gasoline 1.6L I4 power unit, and the biggest one was a gasoline FSI 3.2L 24-valve V6.
