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:

Vehicle	HP	mpg (comb.)	Index
2005 Corvette	400	22.6	9,040
Porsche 911GT2	477	18.2	8,681
Porsche Turbo	444	18.2	8,081
Dodge Viper	500	15.5	7,750
Porsche 911	340	20.6	7,004
Ferrari 575 Maranello	515	12.7	6,541
Ferrari Modena	400	12.7	5,080

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 taillamps 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, Gmbh, 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, Magnetic Selective Ride Control, and Z51 Performance Package. The Standard suspension is tuned for a balance of ride comfort and precise handling.

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.
