Acceleration: Launch control is fairly worthless on our low-grip test surface. Its 5,000-rpm base is too high and its closed-loop throttle manipulation (using front wheel speed) is both too slow and not effective enough. Basically, launch control resulted in a big burnout. I chose a 3,000-3,500 launch rpm and had the best luck with a little clutch slip rather than a dump. Shifter is awesome much better than before. Never missed a gear.

Braking: Solid pedal feel and good response. Consistent performance, but these (optional) P Zero Corsas are clearly less sticky than the optional Michelin Pilot Sport Cup rubber on the Z06 and ZR1.

Skid pad: Heavy understeer attitude, but massive grip. More throttle equals more understeer. Won't respond to lift throttle, which is probably good in a car with limits this high. Steering is direct and immediate. Ran all handling tests in "Street" damping, as "Race" was too stiff and made the car nervous. Feels like this level of damping is really only appropriate at high speed.

Slalom: Because of its limited visibility, the Viper is harder to place than some of its competition, which resulted in hitting more cones than normal. Still, its 73.7-mph speed here is telling. It's stable and relatively easy to control in rapid transitions. Doesn't feel like it wants to kill you anymore, but its limits still demand respect.

The manufacturer provided Edmunds this vehicle for the purposes of evaluation.
