Audi is unveiling the Sportback concept show car at the 2009 North American International Automobile Show. With systematic refinements to the brand’s characteristic design elements, the five-door model offers a glimpse at the Audi's future design vocabulary. With its pronounced coupé-like silhouette and large rear hatch, the 4.95 m long, 1.93 m wide and only 1.40 m high vehicle is boldly progressive for the luxury class.
