Overview
Chevrolet has introduced a new Corvette for 2005, and this sixth generation
of America's
sports car is better than last year's model in every way.
The new styling, with exposed headlamps and a slimmed-down rear end, is the
first thing people notice. But what makes the C6
great is its improved handling, performance, refinement and comfort. It's
substantially shorter and lighter than the previous model, the wheelbase is
slightly longer, and it gets a new engine, new transmissions, new suspension,
new brakes, a new interior and extensive refinements
throughout. Chevrolet says 85 percent of the content in the C6 is new.
It all adds up to a car that's more comfortable and easier to drive, not
only on the road, but also on a race track. The new 2005 Corvette quickly
infuses the driver with confidence. It feels like
it has more grip than the old one, and it does. It's more agile than before
yet more stable, it's new brakes are excellent. And,
yes, it's faster.
Corvette's new 6.0-liter V8, called the LS2, delivers more power than before
for quicker acceleration performance, improved response, increased efficiency
and enhanced refinement. Specifically, the LS2 produces 400 horsepower and
400 pound-feet of torque. Moreover, it sounds great and the acceleration performance
is exhilarating and intoxicating. The coupe is awesome, and the convertible
is really wonderful. Drop the top on a nice day, turn on the stereo and you'll
have what psychologists call a peak experience.
Model Lineup
The 2005 Chevrolet Corvette comes as a coupe or convertible. The Coupe features
a single-piece removable roof panel that's available in body color (standard)
or transparent or you can order one of each. The Convertible gets a new power-operated
soft top.
After choosing the body style, the next big decision is whether you prefer
the four-speed automatic or six-speed manual gearbox. The final big decision
is which of three suspensions to get: the standard suspension, the Z51 Performance
Handling Package, or F55 Magnetic Selective Ride Control with electronically
controlled variable damping.
The Corvette comes well-equipped with leather seating surfaces, climate control
with a pollen filter, a six-way power driver's seat, power everything, and
cruise control. However the side-impact airbags, are included in the two major
option packages: Package 1SA includes a rear area cargo convenience net,
luggage shade, sport bucket seats with perforated leather seating surfaces,
back angle/lumbar adjustment and side bolsters; Package 1SB adds to that a
head-up display, a Homelink transmitter w/garage door opener and three-channel
programming, interior rearview mirror with compass, driver-side auto-dimming
exterior rearview mirror, dual front heated seats, a premium seven-speaker
AM/FM Bose system with six-disc in-dash CD, MP3 playback, power telescopic
steering column with manual tilt, and a memory package with two driver presets
for seat, exterior mirrors, climate control, radio and steering column. The
list of free-standing options is relatively short: XM Satellite Radio, seven-speaker
Bose audio, and polished aluminum wheels.
All 2005 Corvettes come with the same LS2 engine. There's no high-performance
Z06 hard top available (yet), but the lightweight new models with the LS2
are nearly as quick as the old Z06. There is, however, a 3.15 rear ratio available
for the automatic for quicker acceleration performance.
Walkaround
Its body work may be all new, but no one will have any trouble recognizing
the C6 as the Chevrolet Corvette. At the same time, they will immediately
know it's the new one.
The exposed headlights usually draw the first comments. For many years Corvettes
have used hideaway headlamps to complement their sleek, aerodynamic designs,
but advances in optics and lighting technology enable designers to achieve
those goals with exposed headlights. From an engineering standpoint, the new
headlamps are better than the old hideaways: They are lighter, which means
less weight hanging out over the front wheels, a critical area in terms of
overhang, polar moments of inertia, and all that stuff; reducing weight in
front is always difficult in a front-engine car, so this is an important reduction.
They also eliminate a lot of mechanical complexity and allow a higher-quality
lighting setup. And they offer better performance; Chevrolet says lighting
is improved 85 percent.
More important than the headlamps, however, is the Corvette's smaller proportions.
The C6 is fully 5 inches shorter than the C5 (3 inches shorter in front, 2
inches shorter in the rear), and it's 1 inch narrower.
Its smaller size and lighter weight improve agility. The new Corvette also
cuts a tighter, more taut profile. And it does all
that without eliminating usable interior space. The more diminutive dimensions
give it a more international character, says Chevrolet, allowing it to feel
more at home in other parts of the world. Though 5 inches shorter in overall
length, the wheelbase has been stretched by more than 1 inch, resulting in
shorter overhangs; shorter overhangs improve agility, while the longer wheelbase
improves stability. In other words, the wheels have been pushed out toward
the corners of the car.
The body work is smoother aerodynamically and generates less lift in front.
Translation: better grip, increased stability at high speeds. The sculpted fenders, the sharp creases that sweep dramatically up
to the planed rear deck and other aspects of the design call to mind exotic
cars, race cars and jet fighters. The narrower rear end is the biggest
improvement from a styling standpoint, offering more pleasing proportions.
Viewed from the rear, the four jeweled taillights make the new Corvette look
like an F18 taking off in full afterburner mode. The quad tail pipes, black
lower diffuser and tiny rear spoiler accented in black, give it the look of
an Italian exotic. That tiny spoiler is functional, reducing rear lift at
high speeds. Ducts on the trailing edge of the front fenders draw hot air
out of the engine compartment. Chevrolet says it spent more than 400 hours
in the wind tunnel refining the new design, resulting in numerous subtle and
meticulous changes to improve high-speed performance and to route fresh air
to the 400-horsepower engine. The windshield wipers are designed to not lift
off the windshield until you're going 150 in the rain. The optics of the reverse
lights magnifies the light they throw out, helpful when backing up in this
beast.
Interior Features
The interior is all-new for 2005 and much improved over past Corvettes. There's
a two-tone leather treatment available. Chevrolet indicated that some dramatic
changes were needed to meet the expectations of buyers in the new millennium,
so the C6 got premium soft surfaces, beautiful grain in the materials, more
elegant tailoring. The dashboard is finished in a soft material that feels
nice to the touch. The seats are nicely finished. Glare is managed. Real metal
accents are used, but they don't generate glare. The electronics serve the
driver without getting in the way.
The seats are comfortable and easier to adjust than in past Corvettes, though
there's still that feeling of sitting deep down in a massive machine. There's
more headroom, though, and the windshield doesn't seem as close to the driver's
face.
The instruments are big analog gauges that are easy to read at a glance.
The Corvette is, thankfully, devoid of a lot of digital readouts. One exception
is the head-up display, which projects speed, rpm and even g-forces onto the
windshield, a handy and entertaining feature.
There's no need to take the key out of your pocket to unlock the doors or
start the car. Simply walk up to the car and open the door. Sensors detect
your key and unlock the door. Climb in and press the starter button.
The Convertible features an optional power-operated soft top, a feature that
last appeared on a Corvette in 1962. The power top features a single-button
control and completes its cycle in 18 seconds. An easy-to-operate manual top
is standard. The five-layer fabric top is available in three colors. It looks
good with the top up, but looks terrific with it down, with body-color trim
that gives it the racy look of an open-cockpit Le
Mans prototype. The coupe offers 22.4 cubic feet of trunk space.
Driving Impressions
Whether cruising down the road or pushing your limits on a race track, the
new Corvette is much easier to drive than the old one. It rides nicer, the
handling is improved, it generates more grip. When
driven hard, it's more forgiving than the old car.
The low, throaty roar of the LS2 sounds great and generates thrilling acceleration.
Stand on the gas and even the automatic will chirp the rear tires when it
shifts into second. The new LS2 V8 displaces 6.0 liters (364 cubic inches)
making it the largest standard small-block engine ever offered in a Corvette.
It's also the most powerful. Its 400 horsepower and 400 pound-feet of torque
represent a substantial increase over the previous LS1 5.7-liter V8's 350
horsepower and 360 pound-feet of torque. The new Corvette nearly equals the
output of last year's limited-production Z06 model, which came with a special
LS6 engine rated at 405 horsepower. No exotic overhead cams here. This is
an overhead-valve engine that has more in common with a heavy-duty Silverado
than a Ferrari. But it's tuned well and refined. The new Corvette can accelerate
from 0-60 mph in 4.2 seconds and cover the standing quarter-mile in 12.5,
according to Chevrolet. That's quicker than a Porsche 911 Carrera or Jaguar
XK8 and comparable to a Ferrari 360 Modena. There's lots of torque at all
engine speeds. Stand on the gas and it goes. Corvette engineers say the new
car can lap a racing circuit nearly as quickly as a Z06, and boasts a top
speed of 186 mph. But it's quite happy just cruising around and gets an EPA-rated
20/30 mpg City/Highway with the manual (20/28 with the automatic).
Both transmissions are new and both are appealing on their own merits: The
automatic does not sap all the fun out of driving the Corvette the way automatics
do in small sports cars with small engines. The big V8 ensures that. The automatic
is responsive to the driver's intent. It shifts hard and fast when you're
getting with the program, but smooth and soft when cruising. The manual is
now a more viable option as a daily driver than it used to be. Called the
Tremec T56, the six-speed manual shifts more easily than last year's manual
gearbox and the clutch pedal is easier to operate.
The mechanism that forces you to shift from first to fourth when accelerating
slowly (to improve the fuel-efficiency rating) is less intrusive than before.
Fifth and sixth gears are both overdrives, again to improve fuel efficiency.
Shifting through the gears is a lot of fun and it's easy to brake and downshift
using the heel-and-toe method (actually using the ball of foot and side of
foot) when approaching a corner. Still, the automatic is best for commuting
in stop-and-go traffic.
The new Corvette is more agile and easier to toss around than the previous-generation
model, benefits of its lighter weight, trimmer proportions, and refined suspension.
The coupe weighs 3,179 pounds, about 67 pounds lighter than last year's model.
On the road, the new Corvette feels more refined. It's quieter, smoother,
and feels tighter, with less cowl shake than before. Though based on the C5
architecture, the basic structure has been extensively revised for the C5.
Chassis engineers were able to reduce weight substantially, helping offset
weight gains from larger wheels and tires, bigger brakes, sound-deadening
measures and interior features.
It offers great handling, even on a racing circuit. I drove the base model
back to back with the C5 on a short road-racing circuit at GM's proving grounds
and the new one inspires much more confidence. There's almost no body lean
when cornering hard.
The Z51 package makes the Corvette even more fun on a race track. It offers
excellent grip in fast sweepers, with just the right amount of body lean.
I found it easy to roll on the power coming out of the turns. It can generate
0.98g on the skid pad, quite a bit more than the standard suspension's 0.92g.
The F55 Magnetic Selective Ride Control, which some of us refer to as the
electronic suspension, covers both ends of the spectrum, offering the best
of both worlds. The driver can switch between Touring and Sport modes each
of which adjust shock damping automatically according to driving conditions.
In the Touring mode, it varies damping from very soft when poking along to
something close to Z51 stiffness when driven hard. Chevrolet says it's the
world's fastest-reacting suspension. Touring mode seemed a little better than
standard suspension on a two-lane country road near GM's proving grounds in
Michigan. Switching to Sport mode raises the floor
(but not the ceiling) in terms of firmness, so you feel road vibration but
it's not harsh. It's a great setup.
The brakes have been upgraded to improve performance and durability. The
brakes are smooth and progressive, and easy to modulate. The C6 is very stable
under hard braking and the car doesn't get overly unsettled when braking and
turning at the same time. The brakes are bigger than before. Ducts front and
rear help keep the brakes cool, but you have to lay
down on the ground to see them. The Z51 gets bigger brake rotors to reduce
fade with repeated hard braking.

Summary
If you've always wanted a Corvette, this is the one to get. Extensively
redesigned, the C6 is the best Corvette ever. It's easier to live
with, easier to drive and more fun than past models. Of course, it
should be. More to the point, it offers an excellent performance value
when measured against other sports cars, and generates many grins
per mile.
