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 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."
For only the second time in Chevrolet history, a Corvette is now available in a Drivers Series special edition. Actually, there’s four, all Grand Sports designed in collaboration with Corvette Racing team drivers Milner, Gavin, Magnussen and Garcia. The idea came from Chevrolet exterior design manager Kirk Bennion, a racing fan who was also at the Rolex 24, according to Corvette Marketing Manager Todd Christensen. Four Drivers Series special editions is definitely more fun than one.
