Audi A5 and S5 Cabriolet (convertible) production began in early 2009. The A5 Cabriolet included a fabric roof as opposed to a retractable hardtop as on the Volkswagen Eos. The engine ranges are same as contemporary A5 coupé models, but S5 Cabriolet came with a 3.0 TFSI V6 supercharged engine. The A5 Cabriolet replaces the A4 Cabriolet. Delivery of A5 Cabriolet began in the second quarter of 2009. The vehicle was unveiled in 2009 New York Auto Show.

The U.S. versions of A5 and S5 Cabriolet went on sale in September 2009 as a 2010 model. Early models included A5 2.0 I4 TFSI multitronic, A5 2.0 quattro Tiptronic, S5 quattro S Tronic.
