Audi is once again opening up new horizons: the Audi urban concept is a 1+1-seat, ultra-light car for congested urban spaces. The technical study being presented at the International Motor Show (IAA) in Frankfurt does not fit under any of the conventional categories – the Audi urban concept combines elements of a racing car, a fun car and an urban car into one radical new concept. In addition to a Sportback model, Audi is also presenting a Spyder variant.
