The Audi designers have brought together dramatic shapes and athletically taut surfaces in the design of the new A5 Sportback. The stretched wheelbase, the short overhangs and the long, wraparound front lid with power dome emphasize the dynamism of the five-door coupé. The three-dimensionally modeled Singleframe grille is significantly flatter and wider than on the previous model.

The new Audi S5 Sportback has grown significantly inside. Its interior length has gained 17 millimeters (0.7 in), the shoulder room for driver and front passenger up to 11 millimeters (0.4 in) and the rear knee room With 480 liters (17.0 cu ft) of luggage capacity, the A5 Sportback rates among the best in its class. Audi also offers the option of sensor control for opening and closing the standard-fit electric luggage compartment lid.
