No... It's NOT an Audi! It's a 2-stroke DKW F12, the West German version of the Trabant. The badge on the bonnet/hood says 'Auto Union' the historically correct name for the 4 rings badge (each ring stands for each make in the Auto Union group - Horch, DKW, Wanderer and lastly Audi, but DKW was the volume car maker in Auto Union) - 'Audi' is just a modern rebranding of Auto Unions and NSUs.
1986-88 Ford Sierra RS Cosworth or here in the states they were the Merkur XR 4Ti
