The 2002 Corvette's LS1 V8 engine is potent. It produces
350 horsepower and 375 pound-feet of torque (with the six-speed,
360 pound-feet with the automatic). Automatic or stick,
the Corvette is fast traffic. It's quick at the starting
gate, beautifully balanced, surprisingly comfortable, and
built to a far higher standard
than any Corvette in history. While we prefer the 6-speed,
we have to admit that the automatic rams its shifts home
with authority, and there's enough muscle in the LS1 V8
to cover the small performance penalties associated with
auto-shifters.
Unlike most ragtops, the Corvette convertible weighs the
same as the coupe, which means its acceleration performance
is undiluted: 0-to-60 mph in less than 5 seconds with the
6-speed manual transmission, about 0.4 seconds slower with
the automatic. The only performance penalty that goes with
the convertible version is top speed. The ragtop doesn't
share the coupe's aerodynamic efficiency, so it tops out
at a mere 162 mph versus 175 mph for the coupe. Of course,
when the top is down there's more drag and a correspondingly
lower top speed. Still, that's speed that'll get you to
the drive-in in a pretty big hurry -- and the local slammer
even faster.

From a handling and acceleration standpoint, it's tough
to perceive any performance distinctions between coupe and
convertible. Corvette's chief engineer said the structural
design for the new Vette began with the convertible, and
as a consequence no shoring-up measures were required for
the soft-top chassis. You hear the same song from almost
every purveyor of convertibles, but
in this application it seems to be true. If there is any
distinction to be made between the agility and stability
of the Corvette coupe and the new convertible, it would
be all but impossible to discern on public roads.
Significantly, we haven't seen a hint of cowl shake, the
time-honored malady of convertibles wherein the dashboard
and exterior oscillate at differing rates. Ride quality
is decidedly stiff. You don't get a sports car's ability
to change directions without snubbing body roll and limiting
up and down suspension motions, and when you do those things
you're obliged to accept some tradeoff in comfort. Potholes
are easily identifiable in the Corvette. Yet they are not
uncomfortably harsh. We hear them and feel them, but they
aren't jarring and don't unduly upset the handling balance.
Even with the basic suspension package, responses are
surgically precise, if you can imagine a surgical instrument
with 350 horsepower and great gobs of torque. The Corvette
offers sharp reflexes while driving down rural roads. It
provides a superb blend of muscle and finesse, with a much
higher tolerance for mistakes of the enthusiastic variety,
complemented by brakes that are nothing short of race worthy.
Chevrolet's second-generation Active Handling is standard
equipment; it's a magical system that gets you out of slides
before trouble strikes, by applying braking to the individual
corners as needed. It utilizes on-board sensors to measure
yaw, lateral acceleration and steering wheel position, then
brings into play the capabilities of Corvette's standard
ABS brake and traction control systems to smoothly assist
the driver in maintaining vehicle control in oversteer or
understeer situations. Some such systems have been getting
criticism lately, for their hair-trigger qualities, their
eagerness to aggressively assist before the driver
wants or often needs such assistance. Corvette engineers
say that this system has been carefully calibrated to limit
such intrusiveness. Aside from an "Active Handling" message
on the instrument panel, drivers might not even realize
they've been assisted.
Much to our relief, and even surprise, we found this to
be true on the racetrack. We spent two days in the Z06 at
the Rupert Bragg-Smith Advanced Driving School, which is
Chevrolet's official school for high-performance driving.
It's located at a wonderful 2.2-mile rhythmic driver's circuit
Bragg-Smith designed about an hour from Las Vegas. In a
nutshell, we found the Z06 to be rock-steady, precise, consistent,
and, of course, fast. An absolute joy to drive. The brakes
didn't fade. The transmission and shift linkage was solid,
tight, shifting perfectly each time, whether up or down.
Bragg-Smith reports that each three-day school requires
some 4000 shifts of the cars, 12,000 to 15,000 miles in
a year, and there's never been a gearbox problem. Never
been any problem, in fact; he says he only changes the oil
and brake pads (and goes through piles and piles of tires),
and that's it.
The car didn't understeer unless the driver forced it
to, by his own error. It only oversteered in response to
deliberately crude throttle application, and then the Active
Handling brought it back into line by applying the brakes
to the outside front wheel. There was one spot on the track
where the suspension gave a mighty twitch, full on the throttle
in third gear exiting a turn, but it stopped at that one
twitch. It's a new circuit, and still smooth; a bumpy circuit
might have brought different results. But it must be kept
in mind that this is a road car, not a racing car. Its performance
for a road car was beyond impressive. And wildly enjoyable.
