COMMEMORATIVE EDITIONS MARK CORVETTE'S
RACING SUCCESS
The Chevrolet Corvette maintains its
well-earned status as the automotive and cultural icon that has been
admired and sought after for a generation. For the 2004 model year,
commemorative editions for each Corvette model are available so
enthusiasts can celebrate the racing success of the Chevy flagship.
Also, the top-of-the-line Corvette Z06 -
already hailed by enthusiast magazines as the best combination of
performance, comfort and value in the automotive world - gets even better
for 2004 with revised shock valving based on testing at the legendary
Nürburgring race track in Germany.
Corvette also has earned two consecutive
quality awards from J.D. Power and Associates and continues to win
accolades for its surprising interior room, cargo space, comfort and fuel
economy in a high-performance sports car.
Only a handful of cars in the history of
the industry have shown the Corvette's ability to capture the fancy of so
many consumers and hold it for so long. As the golden anniversary
celebration continues, it is a testament to the ability of Corvette's
engineers to keep the car as fresh and cutting edge as it was in 1953.
Corvette has remained relevant because it
continued to embrace new designs and technologies such as those featured
on the current line: Magnetic Selective Ride Control, Goodyear EMT
"run-flat" tires (coupe and convertible), active handling and a rear
transaxle.
Commemorative editions
The commemorative editions recognize the success of the C5-R racing
program. In 2002, the Corvette C5 continued to dominate the field with
nine wins in 10 American Le Mans Series races, also nabbing the 2002 GTS
Manufacturer Champion and GTS Team Champion awards. Combined with a second
consecutive victory at the 24 Hours of Le Mans, Corvette continued to make
history.
The Commemorative Edition Coupe and
Convertible include new Le Mans Blue paint with Shale interior, special
badges and polished wheels. The convertible's top also is Shale to match
the interior.
The Commemorative Edition Z06 also is Le
Mans Blue and also includes a C5-R Le Mans stripe scheme, special badges,
polished Z06 wheels and a lightweight carbon fiber hood.
Z06 ride tempered at Nürburgring
Over the period of a month in 2002, engineers put the Z06 through its
paces at Germany's fabled Nürburgring racetrack to give the definitive
street-legal sports car an even better ride. Since it was completed in
1927, the 12.8-mile (20.6 km) Nürburgring circuit has been the ultimate
challenge for vehicle dynamics. The course has 177 corners, and in between
them is every conceivable combination of radius, camber and gradient - not
to mention altitude that varies by nearly 1,000 feet (305 m). No other
track in the world places such extreme demands on a vehicle's suspension,
brakes and powertrain, which is why Nürburgring is where the world's
finest sports cars are regularly tested.
After a month in Germany, it was back to
General Motors Milford Proving Grounds, where new shock absorber valving
was "dialed in" and balanced for optimum performance on American roads.
The result is a suspension that feels "more
tied down, more glued to the road," said Harlan Charles, product manager
for the Corvette.
Magnetic Selective Ride Control
The suspensions of the 2004 Corvette coupe and convertible continue to
feature Magnetic Selective Ride Control, which debuted in 2003. It uses a
revolutionary damper design that controls wheel and body motion with
magneto-rheological fluid in the shocks. By controlling the current to an
electromagnetic coil inside the piston of the damper, the MR fluid's
consistency can be changed, resulting in continuously variable real-time
damping. As a result, drivers feel a greater sense of security, a quieter,
flatter ride and more precise, responsive handling, particularly during
sudden, high-speed maneuvers.
The system isolates and smoothes the action
of each tire, resulting in less bouncing, vibration and noise. On bumpy or
slick surfaces, the system integrates with traction control to assure
maximum stability. It also works with ABS to keep the vehicle balanced and
poised. It is the only system without electro-mechanical values and no
small moving parts. It consists of MR fluid-based, monotube shock
absorbers, a sensor set and on-board controller
