With Z06, Chevrolet Corvette once again raises the bar for production sports car performance. During testing at two different, 2-mile road race facilities, Grattan in Michigan and Putnam Park in Indiana, (both regularly used by Team Corvette for testing) John Heinricy, boocoo-times-winning and World-Record-holding Corvette racer, and Mike Neal, GM’s top Corvette ride-and-handling engineer, were three-and-a-half seconds a lap quicker in Z06es than in 2000 Hardtops.
When I talked to Mike at Mid-Ohio he offered this, "In the real world, a Z06 might even be quicker. John and I are very experienced on those tracks in Z51s and Z06es. Even above average Z51 drivers, unless they have a heck of a lot of seat time, might not be as fast. Z51’s, because of some differences in their rear suspension, require a more judicious application of the throttle exiting turns than does the Z06. Those unaware of that may not be as quick off turns. I think many drivers will be more like, four seconds a lap faster in the Z06."
Anyway you cut it, three-and-a-half or four seconds is an astonishing gain for a showroom stocker on a 2-mile track.
The bar’s been raised...a bunch.
