The Audi A5 car is the coup� variant of the fourth generation A4 (B8) sedan and estate that was launched at the 2007 Frankfurt Auto Show. The A5 marks Audi's return to the mid-size coup� market since the (B3/B4) Audi 80-based Coupe model ended production in 1996. The Mk 2 (B6/B7) A4 spawned a convertible variant but not a coup�; due to the introduction of the A5, the A4 Cabriolet was not retained for the B8 generation. The A5 is the third coupe in Audi's line-up, next to the second-generation TT and the R8. The A5 has adopted many design elements of the Nuvolari quattro concept. The A5 debuted with the 3.2-liter FSI V6 engine delivering 265 PS (261 hp/195 kW). In 2009, Audi announced the S Tronic transmission option for A5 with 2.0L TFSI quattro in UK market.
The Audi A5 Cabriolet (convertible) is scheduled for production in early 2009. Audi has released the official details of the model on December 3 2008. It is confirmed that the A5 Cabriolet will have a fabric roof as opposed to a retractable hardtop as on the Volkswagen Eos. The Audi A5 keeps the same engines as the coup�, including the 2.0-turbo engine producing 211 PS (155 kW; 208 hp) and the 265 PS (195 kW; 261 hp) 3.2 L V6, with a 2.7 L TDI option. The Audi S5 Cabriolet feature the new 3.0 L Supercharged V6 producing 333 PS (245 kW; 328 hp).
