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.
1993 Corvette C4 40th Anniversary ZR-1 parked on street
In 1993 just 448 ZR-1 Corvettes were produced and only 240 of them were 40th Anniversary Edition cars. The 40th Anniversary Package consists of a deep and glossy Ruby Red exterior finish over a matching Ruby Red interior with leather adjustable sport seats. A Corvette with both of these highly desirable packages is rare and special. At the heart of the ZR-1 is the 405-horsepower LT5 V8 engine mated to a 6-speed manual transmission.
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.
