The Ron Fellows ALMS GT1 Champion Edition Corvette was introduced as part of the 2007 Corvette line-up. To commemorate Mr. Fellows long and successful career with the Corvette Racing program, Chevrolet introduced the Ron Fellows Championship Edition Z06 Corvette as part of their 2007 model line-up. It was released as a commemorative model to celebrate one of GM's winning-est drivers, but did little to impress enthusiasts or collectors when first introduced.
The 2023 Corvette Z06 pace car uses the same 670-horsepower 5.5-liter naturally aspirated V8 as the road-going version. It has the Z07 Performance Package that has additional features like Magnetic Ride Control 4.0 calibrations, carbon-fiber wheels with Michelin Sport Cup 2 R ZP tires, and carbon-ceramic brakes. The pack also adds carbon pieces to the body.
The early C4's had their problems, what with the 1984 Cross-Fire Injection and its unusual 4+3 manual transmission. By the late 1980's, the fourth-generation Corvette had evolved into a more desirable automobile, thanks in part to the arrival of the ZR-1. 
The Nivola may be considered Bertone’s homage to the most fascinating American sports car: the Chevrolet Corvette. The sophisticated mechanical unit of the ZR-1 was interpreted by Bertone in a European key. Bertone designed a special chassis to make a sporty "boat" with a mid engine. This mechanical layout made it possible to exploit all the power of the engine when accelerating and warrant perfect roadholding on bends.
How do you beat a slew of Fox-Body 5.0 Mustangs that seemingly dominated the roads in the late '80s? You take a 454 cu.-in. big-block engine and stuff into a C4 Corvette and call it "Big Doggie". An experimental vehicle used to determine how to convert from a small block to a big block. Its 454 big block V8 along with its orange paint make this high horsepower engineering study a one-of-a-kind standout in Corvette history. The car had as much HP as the '90 ZR-1 did and it was named "ZR-2" or "Big Doggie". Old dog, new tricks joke?
