Audi has launched its all-new A5 and S5 Coupé at the company's headquarters in Ingolstadt. Lighter and more economical than the outgoing model, the new A5 Coupé is powered by a choice of petrol and diesel engines, with the highlight being the S5’s 3.0-litre TDI engine which pumps out 354PS enabling a 0-62 time of 4.7 seconds. Undergoing both a technological transformation and styling evolution, the A5 Coupé has been aerodynamically optimised, while interior space is more generous. Oder books open at the end of the summer with pricing yet to be announced.
