THE SIXTH-GENERATION CHEVROLET CORVETTE:
MORE POWER, PASSION, AND PRECISION
Marking the sixth-generation of its legacy, the 2005 Chevrolet Corvette delivers more
power, passion and precision to reach a new standard of performance car excellence.
The 2005 Corvette Coupe production begins in the
summer of 2004, with the Convertible following in the fall of 2004. Sales in North America
will occur immediately thereafter, with European sales starting in October, and other
regions in early 2005."The sixth-generation represents a comprehensive upgrade to the
Corvette," said Dave Hill, chief engineer of the Corvette and vehicle line executive
for GM Performance Cars.
"Our goal is to create a Corvette that does more things well than any performance
car. We've thoroughly improved performance and developed new features and capabilities in
many areas, while at the same time systematically searching out and destroying every
imperfection we could find." |

The sixth-generation Corvette blends technical sophistication with expressive
style:
Five inches shorter than the current car, the 2005 Corvette cuts a tighter, more taut
profile - with virtually no loss of usable space. More than just visual, the new
dimensions make the car more agile and "tossable," with upgrades in handling,
acceleration and braking. |
Beyond the lean new dimensions, the 2005 Corvette
features significant upgrades in every area of the car. The new 6.0-liter LS2 V-8 engine
takes the standard Corvette Coupe and Convertible across the 400 hp (298 kw) threshold,
delivering a dramatic increase in acceleration with excellent efficiency. With base curb
weight starting at 3,179 pounds/1,442 kg (Coupe) and 3,199 pounds/1,451 kg (Convertible)
the new Corvette is significantly lighter than its predecessor - despite improved
structure, larger wheels and tires and greatly increased interior features. 
The Convertible features an optional power-operated soft top for the first time since
1962. Technologies such as Keyless Access and DVD-navigation make their first appearance
on Corvette. At 0.28 coefficient of drag, the sixth-generation is the most aerodynamically
efficient Corvette ever and has improved anti-lift characteristics that enable improved
high-speed stability and confidence.
"The 2005 Corvette is more competition-influenced - given our championship experience
with Corvette Racing - than any previous Corvette," Hill said. "Our goal was a
performance car at home in virtually any environment. That means more than just raw
performance. It calls for improved ride comfort, a precisely-built and
technically-sophisticated interior, and a sleek new body that is fresh and contemporary,
while still instantly recognized as the new Corvette."
The development of the sixth-generation not only replaces the outgoing "C5"
Corvette (1997-2004), but also creates a 21st century Corvette that both thrills the
legions of traditional loyalists and also captures the imagination of a new generation of
performance enthusiasts. The formula from the C5 era remains: extremely high performance
capabilities in a car that offers great style, value and quality, with surprising comfort
for daily driving. The sixth-generation builds on that foundation and reaches beyond with
dramatic increases in performance and refinement, wrapped in a passionate new design.
With countless enhancements, ranging from major changes to minor adjustments, the
sixth-generation aims to perfect the Corvette formula of power, passion and precision
delivered with great value.
POWER
A new LS2 6.0-liter small-block V-8 is the standard engine in the 2005 Corvette. It is
based on GM's new Gen IV small-block family of engines.
The LS2 raises the bar for standard performance in the Corvette, delivering estimated peak
output levels of 400 horsepower and 400 lb.-ft. of torque (298 kw and 542 DIN n-m). It is
the largest, most powerful standard small-block engine ever offered in Corvette.
The 2005 Corvette is capable of a top speed of 300 km/h (186 mph), faster than any
production Corvette in history. The 2005 Corvette reaches zero to 100 km/h (62 mph) in 4.2
seconds. With the optional Z51 Performance Package, 0-100 km/h acceleration time improves
to 4.1 seconds. The 2005 Corvette covers the quarter-mile in 12.6 seconds at a speed of
183 km/h (114 mph).
Major revisions to the manual and automatic transmissions provide Corvette with
significant improvements geared towards performance driving. The Tremec six-speed manual
gearbox is available with two sets of ratios, one with more aggressive acceleration
characteristics reserved for Corvette's Z51 Performance Package that emulates the
performance of the C5's landmark Z06 model. Improved shifting characteristics are another
major improvement, with new synchronizers that reduce travel by 10 percent, and a shifter
knob that is an inch shorter and redesigned for greatly improved driver operation.
The Hydra-Matic 4L65-E automatic transmission is an upgraded version of the C5's 4L60-E,
strengthened and revised to accommodate the LS2's 400 lb.-ft. of torque. It includes GM's
advanced Performance Algorithm Shifting, which automatically selects the optimal gear for
a given driving condition, making it a willing accomplice for performance driving and hard
cornering.
The transmission now shifts at higher revs to take advantage of the higher engine output.
While some focus primarily on engine displacement, the Corvette - with its low vehicle
mass, world-class chassis dynamics and the 6.0-liter LS2 V-8 engine - delivers incredible
real-world efficiency on a total vehicle basis. While the car's final fuel economy is yet
to be officially certified, the 2005 Corvette is projected to mirror the 2004 version in
fuel economy, with a combined city/highway mpg rating estimated to be between 22 and 23.
Corvette boasts the best combination of horsepower and fuel economy among the world's best
performance cars. When the LS2's 400 horsepower is multiplied by its combined city/highway
mileage estimates, it yields a total of 9,040. Here's how the 2005 Corvette compares with
some of its key competitors:

The bottom line? Corvette delivers power in the range of exotic cars that cost tens of
thousands more, combined with fuel efficiency better than some family sedans.
PASSION
The signature of the sixth-generation is an expressive new design that is a worthy
extension of the Corvette lineage, distilling classic Corvette design cues in a completely
fresh and contemporary fashion.
The sixth-generation features a taut new body with greatly revised exterior dimensions - 5
inches shorter than the C5, and roughly 1-inch narrower - with excellent aerodynamics.
This new package not only aids the car's agility and performance, it also helped designers
give the sixth-generation a lean, muscular form.
The new Corvette
features more character and flair, expressed in an absolutely purposeful manner. The car
includes larger wheels (18-inch in front, 19-inch in rear) topped by dramatic fender
forms, with a crisp and tapered rear deck and fascia that support improved high-speed
performance. Compared to the outgoing C5, this new generation Corvette has much more
character in its front and rear fascia areas. The exposed lamps combine with the grille to
create much more of a "face" on the car.
The rear fascia is more expressive and lean, with truly round tail lamps and integrated
exhaust tips.
While using the latest advanced computer-aided design techniques, the styling of the 2005
Corvette relied heavily on traditional hand sculpting and the personal passion of
designers and engineers. Sculptors pored over every millimeter of the car's surface. The
aerodynamic development combined digital simulations, Corvette Racing experience and more
than 400 hours of wind tunnel testing.
The passion on the outside is reflected in an all-new interior. The twin-cockpit layout
incorporates sophisticated contours, leather-like surfaces that are richer and softer, and
pleasing details including metallic accents and an expressive use of color.
PRECISION
Interior
| A central element of the 2005 Corvette is an
all-new interior that includes greatly improved materials, craftsmanship and
functionality. The interior delivers premium quality with new technology meant to enhance,
not distract from, performance driving. The
sixth-generation continues the dual cockpit design theme that has been a Corvette
hallmark. The instrument panel and door trim areas make extensive use of cast skin, which
retains the look and feel of genuine leather with excellent softness, low gloss and low
glare that conveys an overall premium appearance and quality. Anodized aluminum accents
the interior in key functional areas, such as the manual shift knob and door release
buttons. |

This material includes a screen-printed appliqué that minimizes sun glare, and is
resistant to temperature changes and fingerprints.
|
Exterior
The 2005 Corvette features exposed headlamps, the first time since 1962 that a production
Corvette has not had a mechanism to conceal the lamps when not in use. The fixed Xenon
High-Intensity Discharge lamps provide superior lighting performance in a compact,
high-tech package that integrates seamlessly into the design and aerodynamics of the car.
The sixth-generation Corvette Convertible features an optional
power-operated soft top, a feature that last appeared on the car in 1962. The power top
features a single-button control and completes its cycle in 18 seconds. The top is
designed and manufactured in partnership between GM and Car Top Systems, GM, experts
who've contributed to some of the world's most celebrated open cars. An easy-to-operate
manual top remains standard.
The Convertible features a five-layer fabric top, available in three colors, that conceals
the underlying structure well for good top-up appearance as well the preservation of the
car's excellent aerodynamics. |
Technologies
Corvette contains many new electronic technologies including Keyless Access with
push-button start, and optional features such as a reconfigurable head-up display,
DVD-navigation system with voice activation, XM Satellite Radio and OnStar.
Chassis
As the next logical step in the evolution of GM's Performance Car Architecture, the new
Corvette chassis and structure are significantly enhanced. While the overall design
philosophy continues from the C5 Corvette, the details contain a host of improvements.
The key features of the structure - low weight, high strength, cored composite floors,
enclosed center tunnel, rear axle-mounted transmission and aluminum cockpit structure -
all have been extensively revised to extend Corvette's total performance, with enhanced
structural integrity, feel, refinement and quietness. Overall vehicle weight is
significantly reduced, despite mass-increasing features such as larger wheels and tires,
more robust brakes and increased body acoustics and interior features.
Suspension
None of the suspension bits have been carried over from C5. The short-long arm and
transverse leaf spring independent suspension configuration remains, but the cradles,
control arms, knuckles, springs, dampers, bushings, stabilizer bars, and steering gear are
all redesigned. The Extended Mobility Tires (EMT) also are new, taking advantage of the
latest sidewall design and compound technology for run-flat capabilities, and play a
critical role in the tuning of the suspension for excellent handling and comfortable ride.
Suspension Choices
Three suspension choices allow drivers to choose the setup that best suits their driving
style -
Standard,
(Standard suspension is tuned for a balance of ride comfort and
precise handling.)
Magnetic Selective Ride Control,
Z51 Performance Package.
Ride & Handling
Improvements in ride and handling include greater lateral acceleration, more body control,
less noise transmitted from the road, and better traction and stability in corners. The
specific tuning changes in the chassis and suspension include suspension and steering
geometry optimized for better handling and ride, advanced compounds in the tires, new
directional control arm bushings, increased caster angle and greater suspension ride
travel. The result is a Corvette that is more poised at even higher handling levels, yet
easier to drive.
Magnetic Selective Ride Control
The optional F55 Magnetic Selective Ride Control suspension features magneto-rheological
dampers able to detect road surfaces and adjust the damping rates to those surfaces almost
instantly for optimal ride and body control. Magnetic Ride Control debuted on the 2003
50th Anniversary Edition Corvette, and is the world's fastest reacting suspension,
replacing mechanical valves with nearly instantaneous reactions of magneto-rheological
fluid. The system has been improved for the 2005 Corvette, allowing drivers more
differentiation in character between the system's two settings, "Tour" and
"Sport."
Z51 Performance Package
The Z51 Performance Package brings Corvette Coupe performance very close to the same level
as the widely admired Z06. The Z51 offers more aggressive dampers and springs, larger
stabilizer bars, and larger, cross-drilled brake rotors for optimum track performance
capability while still providing a well-controlled and comfortable ride. Extensive
racetrack testing reveals that a 2005 Corvette equipped with the Z51 suspension almost
equals the lap time of a 2004 Z06 - marking a major advance in the overall performance of
a Corvette Coupe by approximating the extreme performance capabilities of the vaunted Z06
at a remarkable value. |
Eliminating Imperfections
The new Corvette also seeks to eliminate the little imperfections and potential
"dis-satisfiers" that sports car customers formerly had to accept. All of the
major user interfaces - the hood, the doors, and the rear hatch - have been painstakingly
designed for top quality performance, look and feel. The hood is still forward-hinged, but
is 15 percent smaller, 35 percent lighter, and 40 percent stiffer than the previous
Corvette. The rear hatch has a power-operated single-cinching latch for excellent fit and
easy operation. Doors are stiffer and easier to close, doing so with a more refined sound.
There are no traditional door handles on the 2005 Corvette. The new Corvette features GM's
Keyless Access with Push Button Start technology. By detecting the proximity of the key
fob, the system both unlocks the doors and allows it to be started.
The Coupe's removable-roof panel is 15 percent larger, yet offers the same structural
stiffness as C5's while weighing just one pound more. The roof panel comes standard
painted body color, or is available with optional tinted clear or with a dual-roof
package.
With new indexing side-window glass and redesigned seals, Corvette is much more free from
wind noise, too. And the many improvements in tires, suspension, and body structure yield
impressive reductions in road noise, while improving overall quality perception and making
long trips that much more pleasurable.
