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.
The 2010 Grand Sport Corvette was introduced to the world at the 12th annual C5/C6 Corvette Birthday Bash, which was (and is) held at the National Corvette Museum in Bowling Green, Kentucky.  During its unveiling, it was announced that the new Grand Sport would be offered as either a coupe or a convertible, and it would feature an appealing combination of the LS3 power plant fused with the Z06 Corvette’s wide track chassis and styling features.

Immediately following this unveiling, consumers began clamoring at the opportunity to become one of the fortunate few to own their own IMSA GTLM Championship C8. Chevrolet filled all 1,000 orders for the race-inspired commemorative C8 in record time, as production commenced. Those lucky enough to place their order before the mandatory production cap was reached, were treated to a handful of IMSA GTLM Championship C8 variants to choose from.
