Our first full test of the $53,000, all-wheel-drive 2008 Audi S5 was a bit of a revelation. With a 354-horsepower version of Audi's direct-injection 4.2-liter V8 under its hood, the voluptuous Audi S5 ran a 13.3-second quarter-mile at 104 mph, just 0.1 second and 2 mph shy of the 420-hp 2007 Audi RS4 sedan. What's more, the S5's slalom speed is within a couple mph of the harsh-riding RS-spec sedan. It ran a 13.3? With that kind of speed, who needs a $67,000 RS4?"" we asked ourselves.
