It's 30 years since Audi Sport quattro stunned the racing world. On this landmark anniversary Audi recently revealed a new, powerful successor in the shape of a concept vehicle at the 2013 IAA in Frankfurt. With a system output of 700 hp and accelerating from 0 – 100 km/h in 3.7 seconds, the new Sport quattro continues a tradition of driving exhilaration.
