Audi built about 2500 units of the Quattro Competition for the German and European market. It was a street homologation of the B4-based Super Tourenwagen Cup (STW) race car saloon with four-wheel drive and a modified 140 PS, 16-valve, two-litre petrol engine. The powertrain had its roots in the two-litre, four-cylinder inline engines that most European Audi 80s were equipped with at the time. On the outside, the Quattro Competition featured the same bumpers as the S2, V6 headlights, and a rear wing mounted on the bootlid. Together with the S2 and the RS2 Avant, the Quattro Competition has become an increasingly rare and highly sought-after collector's item. paimta is http://en.wikipedia.org/wiki/Audi_80
