Chevrolet Corvette Coupe

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 C6 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 development of the C6 intends to not only replace the outgoing C5 Corvette (1997-2004), but also to create a 21st century Corvette that both thrills the legions of traditional loyalists and 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 C6 builds on that foundation and reaches beyond with dramatic increases in performance and refinement, wrapped in a passionate new design.

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. At 0.28 coefficient of drag, the C6 is the most aerodynamically efficient Corvette ever and has improved anti-lift characteristics that enable improved high-speed stability and confidence.

“The C6 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.”

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.

A new LS2 6.0-liter small-block V-8 is the standard engine in the 2005 Corvette C6. 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. It is the largest, most powerful standard small-block engine ever offered in Corvette.

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.

Not only does the LS2 engine deliver impressive horsepower, but in a true measure of real-world efficiency, it also 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 22.6 mpg combined city/highway mileage estimates, it yields a total of 9,040.
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.

C6 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 C6 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.
