The Ur-S4 (Ur short for Ursprünglich or original in German) was the first hot version of an Audi sedan to wear the S4 badge, but it wasn’t based on the A4. Instead it used the Audi 100 platform which was eventually renamed the A6 and the Ur-S4 became the Ur-S6. It doesn’t really matter, but if you want an early 90s German car with some oomph, picking up a Ur-S4/S6 isn’t a bad way to go.

The Ur-S4 uses a 2.2 liter version of Audi’s turbocharged 20-valve inline-4 cylinder engine producing 230 horsepower and 258 ft-lbs of torque. Those power figures aren’t huge by today’s standards, but they put it squarely on target with the Mercedes-Benz 190 2.5-16 Cosworth or BMW E36 M3. Only the Audi had standard all-wheel-drive, which helps in hard launches, but slows the car down in the turns due to a fairly hefty 3800 curb weight with a large percent over the front wheels.
