Another decade – another milestone anniversary edition Corvette. However, the 2003 model year was especially significant as it marked the 50th year of the Corvette’s production at Chevrolet.  To commemorate a half-century of manufacturing, every Corvette built in 2003 was adorned with special “50th Anniversary” badging – a unique “50” badge on each of the front fenders above the bodyside coves, and a special crossed flags badge that included “50 Anniversary” badging.
The 638-hp, 6.2-liter supercharged V-8 LS9 engine features such niceties as titanium connecting rods and intake valves, a forged steel crankshaft, and a dry-sump oil system. The suspension has magnetorheological shocks that enabled Chevrolet engineers to use softer springs than in the conventionally damped Z06. Corvette's top dog model is no joke and an accomplished sports car that puts up a good fight against the world's best.
There were several successful attempts to build a convertible ZR-1, most of them by private people. The DR-1 was a GM prototype to test the structural integrity of the ZR-1 chassis when it would be topless. The car was built by American Sunroof Corporation (ASC) for Don Runkle, who was the vice-president of Advanced Engineering Staff, which explains the “DR-1” designation. It was a standard convertible transformed to ZR-1 specs.
Corvette performed Indianapolis 500 Pace Car duties for a record sixth time. It marks the third consecutive year and 15th time overall that a Chevrolet product has served as the Official Pace Car – the most appearances by any brand. The 2004 Corvette that will serve as the Indy 500 Pace Car is virtually identical to the Convertibles available today through local Chevrolet dealerships.

The L71 was Chevrolet’s most powerful engine in 1967 which replaced the big-block L71 from the previous year. Using it’s famous ‘Tri Power’ intake manifold was rated by the factory at 435 bhp. Costing $437.10, 3,754 Corvettes were made with the L71 options and they could not come with automatic transmissions nor air conditioning.
This is no ordinary C4 coupe, but a GM Engineering test mule with VIN plate EX4607 proudly displayed in the windscreen, built in 1986 to test all the new-for-1988 features. This actual car must have spent weeks pounding round the General Motors Proving Ground at Milford, Michigan with longer runs on the road, testing all the changes for a year which saw the C4 suspension, steering and brakes vastly improved.
