The C4 version of the Corvette ZR-1 is an underrated supercar. Looking like a standard Corvette, its heart is a Lotus-designed 32-valve dual overhead cam V8 producing 375 horsepower. Extremely fast by the standards of the time, it set a 24-hour endurance run averaging 175.9 mph and is still fast today.
How fast? That's what the team at TFL Classics decided to find out. They set up a drag race between a 1990 Corvette ZR-1 and a 1988 L98 Corvette. The owner of the ZR-1 made some performance modifications and thinks his car makes about 425 horsepower, 180 more than the regular Corvette.
