DETROIT, Mich., Jan 11, 2009 - Debut in Detroit: 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 coupe-like silhouette and large rear hatch, the 4.95 m long (16.24 ft), 1.93 m wide (6.33 ft) and only 1.40 m high (4.59 ft) vehicle is boldly progressive for the luxury class.
