The A5 Sportback has four framless doors and a long, tapering roofline, giving it a "coupé-like" appearance. It is designed to be "as emotional and elegant as a coupe, as comfortable as a sedan, and as practical as an Avant" according to Audi. While it shares many exterior cues with the A5 coupé, the Sportback's interior is actually more similar to the A4 sedan; although all A5 models have same platform as the A4, the Sportback is closer in design to the A4 than the rest of the A5 family.[11][12] The Sportback has been described as "a sedan with the front end (including an identical S-line look) and taillights of the A5 coupe but the wheelbase of the A4", with the Sportback positioned more as the "designer's car" compared to the more conventional A4 sedan.[13] The Sportback model is available in Europe, Japan, Australia, New Zealand, Middle East, Mexico and South Africa, and starts at €36050. However it is not sold in the United States and Canada.[14] Early production models included 2.0 TFSI quattro 155 kW (211 PS; 208 hp), 3.2 FSI quattro, 2.0 TDI 125 kW (170 PS; 168 hp) with 6-speed manual gearbox and start/stop system, 2.7 TDI, 3.0 TDI quattro. Production version went on sale in September 2009, with additional unannounced models beginning in the middle of 2010.[15][16][17] The A5 Sportback is available with two petrol engines or three diesel engines.
