"Official" Performance Figures For The C7 Stingray Are Here… And They're Grand

The first source of performance numbers for the new C7 Corvette is, not surprisingly in this day and age, GM itself. Some of the numbers are extremely useful, others less so.

First, the basics. The C7 Stingray, when equipped with the Z51 Performance Package, turns a quarter-mile of 12.0@119. If you’re interested in comparing the C7 to the Dodge Omni Miser or something like that, the completely irrelevant 0-60 number is 3.8 seconds. Slightly more interesting, the 60-0 is 107 feet.

So far, so good. This is a properly quick car that appears to have a slight edge on the C5 Z06 and base C6. And to show what great guys they are, the GM Performance crew ran the car around VIR. But, as has been the case with some of their other Corvette testing, they ran the “Grand Course”. To understand what the “Grand Course” is, check the VIR website.

I’ve said it before and I’ll say it again, but Grand Course times are chickenshit stuff. The number of open-lapping days that use the Grand Course can be counted on a single hand in any given year. Races rarely occur on the Grand Course, because putting a race on the Grand Course requires one zillion flaggers and it increases the length of the lap by almost a minute. Thousands of driver/car combinations set VIR Full Course times every year, as I did with the Shelby GT500. By using a Grand Course time, Chevrolet’s insulated the car from any comparisons other than with Car and Driver’s “Lightning Lap”. I could also go on at length about the increasing difficulties in consistency you get when you add something like twisty the VIR Patriot Course to any laptime (the “Grand” is “Full” plus “Patriot”), but I won’t bother to do it.

So Chevrolet’s given us a meaningless laptime. I suppose we should be grateful for whatever we get. On the day when the first C7 is available, perhaps they’ll let me run it around VIR Full, maybe in conjunction with a tuned-up C5 Z06 or something, and we can get a number that every bench racer in America can properly pick apart, right?
