Like all of our Long Term Road Test vehicles, our resident Senior, the 2002 Chevy Corvette Z06 hit the test track as a sort of "welcome" party.

You've no doubt seen the results of our Corvettemageddon face-off: C5 Z06, C6 Grand Sport and C6 Z06 Carbon (droooool). For now, we're going to focus not on the yellow monster that tugs at my heartstrings, but on our 2002 Z06.

Acceleration Comments: As usual, launching a Corvette isn't particularly difficult UNLESS its rear tires are beat (nearly to the wear bars). As such, the launch requires more finesse to achieve the optimal wheelspin/chatter without boiling the rubber. Shifter feels not just heavy, but also binding and as if it needs some sort of lube thrown down the shift boot and into its guts. The transmission gates are unmistakable with definitive slots/stops. Linear power all the way up to 6,500-rpm fuel cut-off where you'll find a hard rev limiter. The car made a faint pinging/detonating sound on the first run that thankfully went away subsequently. Also, this thing is damned loud -- and I mean that in a good way.

Braking Comments: Very firm pedal (hard, in fact) that doesn't impart much information to the driver. Very little dive, zero squirm and the brakes like a little heat in them and the shortest stop arrived on the sixth run. I did, however, experience a squishy, slightly fading pedal on the quarter-mile passes that came directly after.

Handling Comments: Skid pad: Steering loads up quite a lot, and with ESP off, the car is neutral up to the point when it begins drifting wide of the circle with slight understeer. With ESP on, it keeps the car spot-on the painted line with both throttle closing and brake application. Slalom: The first run with ESP off and in 3rd gear resulted in a tank-slapper at the exit. The remaining ESP-off runs were in 4th gear to subdue twitchiness. Good turn-in and neutral until the exit where the rear steps out a bunch. The tires are obviously tired because there's more time to be had in this car, but not with the worn/hard tires as they are. They feel like they're one burnout contest away from the dumpster.
