It took a while, but earlier this month we finally managed to break-in our Long Term S5 and take it out to our test track.
The 2009 Audi S5 has some 349-horsepower from a 4.2-liter V8, quattro all wheel drive and a six-speed manual transmission. More importantly, perhaps, it's rollin' on super-sticky Dunlop summer tires. More importantly, certainly, this thing is nearly 4,000 pounds.
So what'd it do? Follow the jump for quarter-mile, slalom, skidpad and braking tests.

Acceleration Comments: Prefers slipping clutch launches, but you only get a few before it begins to smell, but it never slips. First gear is pretty short, shifts are at the mercy of the clutch damper, but gates are easy to find. Throws are a little rubbery / notchy. Long, linear "legs" in comparison to the R8 that feels much sharper, snappier.
Braking: Strong brakes, medium-firm pedal, very good fade resistance, little dive in "dynamic" mode.
Skidpad: " With ESP off, the S5 can be steered with the throttle (e.g. lift to tuck the nose in). Steering is light and not very informative. With ESP on, the throttle closes and drives around with the gas on the floor.
Slalom: Little, minute brake applications w/ESP on, then throws the anchor. best run was tidiest run with as little upset as possible. With ESP off, it gets loose but is always catchable. Still, the quick run was the cleanses/closest to the cones. Steering is quick, precise, but lifeless.
