The Zagato company took a C7 Corvette Z06 and transformed it into the IsoRivolta GTZ, a "spiritual descendant" of the Iso Grifo A3/C (Corsa).  The original A3/C race car was developed by Giotto Bizzarrini not long after he left Ferrari, where he had served as cheif engineer behind the 250 GTO, which is revered as the world's most expensive car.  Bizzarrini purportedly fancied the A3/C as his "own personal evolution of (and improvement upon) the GTO design."
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 2018 Carbon 65 Edition Corvette
As the 2018 model year approaches, the Chevrolet Corvette is about to reach another important milestone – its 65th anniversary! The Corvette, which for the past six-plus decades has been recognized as the nation’s most popular sports car, made its debut in Flint, Michigan on June 30, 1953.  To commemorate the car’s 65th anniversary milestone, Chevrolet is introducing the Corvette Carbon 65 Edition as an available option on the 2018 Grand Sport 3LT and Z06 3LZ models.
2013 427 Collector Edition Convertible
The 2013 Corvette 427 Convertible served double-duty as a commemorative edition model.  While it marked the departure of the sixth-generation Corvette. The real selling-point was the powerplant at the heart of the car - a 427-cubic-inch (7.0L) LS7 engine, the same engine used in the C6 Corvette Z06.  Rated at 505 horsepower (377kW) and 470lb.-ft of torque (637 Nm), this 427 was the most powerful engine GM had ever installed in a production Corvette convertible to date.
The Z06 arrived for the 2006 model year as a homologation vehicle in the third quarter of 2005 and is the lightest of all Corvette models. The Z06 was equipped with the largest-displacement small-block engine ever produced, a new 7,011 cc (7.0 L; 427.8 cu in) V8 engine codenamed the LS7. The engine has a power output of 505 hp and 470 lb⋅ft.
