C5 Corvette (1997-2004)

Fifth Generation of a Legend

2003 Corvette Coupe & 1953 CorvetteThe 'C5' fifth generation Corvette was produced from 1997 until 2004, with Coupe, Convertible and Z06 variants available.

A Golden Tribute

The 50th Anniversary Edition, which was available only during the 2003 model year on coupe and convertible models, is a tribute to a half-century of automotive leadership. It includes special 50th Anniversary Red exterior paint, specific badging, unique Shale interior including color coordinated instrument panel and console, and champagne-painted anniversary wheels with special emblems. It also features embroidered badges on the seats and floormats, padded door armrests and grips and a Shale convertible top. The Anniversary Edition includes the standard Corvette LS1 engine, as well as Magnetic Selective Ride Control. A special 50th Anniversary Edition of the 2003 Corvette was the Official Pace Car of the Indianapolis 500, marking the fifth time that a Corvette has paced the race.

2004 Commemorative Edition marks Corvette's Racing Success

2004 Corvette Indianapolis 500 Pace CarThe 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 were 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 Nurburgring race track in Germany.

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.

Magnetic Selective Ride Control

Magnetic Selective Ride Control was introduced 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.

2004 Corvette Z06 CoupeZ06 Ride Tempered at Nurburgring

Over the period of a month in 2002, engineers put the Z06 through its paces at Germany's fabled Nurburgring 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) Nurburgring 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.
