| Acceleration comments | Prefers slipping-clutch launches, but you only get a few before it begins to smell, but 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 rating | Excellent |
| Braking comments | Strong brakes, medium-firm pedal, very good fade resistance, little dive in "dynamic" mode. |
| Handling rating | Excellent |
| Handling comments | "Skid pad: 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 application with 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 cleanest/closest to the cones. Steering is quick, precise but lifeless, hates the hop!" |
