Once we completed all of our rating, measuring and testing, the Porsche eked out a narrow victory over the R8. Its crushing advantage in acceleration as well as a few unique features made the difference. Yet we never felt the Audi R8 suffered in the comparison. In fact, the Audi R8 makes the Porsche 911 Turbo feel old.
