The Audi A5 is one of the most versatile models in the Audi portfolio. It is based on the A4 platform, and came in 2007 as a two-door coupe and the powerful S version on the market. In early 2009 was followed by the convertible with a fabric roof, as a replacement for the A4 Cabriolet. The five-door hatchback variant is called the Sportback and is also an S-model on the market. The Audi A5 family is crowned by the four-wheel drive RS5 top model with 4.2-liter V8 engine and 450 hp.
