Audi S4 (First Gen) vs. Porsche 944S

This came about as The_Canuck and I were talking about cars that we could afford in the future. He commented that he wanted an S4, while I said I wanted a 944. Then I suggested that we vs. each other on a track day at Mosport (our local racetrack- well not so local for him). Ok, I am not sure whether to use the 944S or the 944 but I am tired and just gonna stick with the base after changing my mind midway through. So I wonder what you guys will tip the hat to? We will see... (Stats from Wikipedia mostly) Audi S4 (1991-1994) Engine: 2.2L Turbocharged 4 valve per cylinder I5 Drive: AWD Power: 169 kW 227 hp Torque: 350 N·m 258 lb.-ft. Mass: 1536 kg 3384 lb.
