While reading the Corvette Forum over the weekend I came across a post titled “Yes, the ZR1 is Faster :)” by forum member named “Poor-sha” that I wanted to share here as it illustrates the raw power of the Corvette ZR1.
Over the span of two days in late January, Chevrolet shared two official videos of the Corvette Z06 and ZR1 running the Grand Course at Virginia International Raceway (VIR). Both cars were driven by Corvette Engineer Jim Mero and both videos feature stock cars on the same Michelins with only the addition being safety equipment.
First up was a 2017 Corvette Z06 which just was being tested with the new magnetic select ride control calibrations that were introduced two months previously at SEMA. With these calibrations installed, the Z06 ran the grand course at VIR in 2:39.77.
The Corvette ZR1 was also heavily tested at VIR and the following day, Chevrolet released that video showing a ZTK-equipped Corvette ZR1 making quick work of the Grand Course with a lap time of 2:37.25 – about 2 1/2 seconds faster than the Z06.
Poor-sha took screenshots from these laps at VIR from both videos at the same locations on the track and put them side by side so you can see just how much faster the ZR1 is on the track and the results are startling:
Our view is that, of course the ZR1 should be faster as it has better aerodynamics and over 100 hp on the Z06. With those features, Jim Mero was able to gain 2.5 seconds on a four-mile track over the Z06. But seeing some of these times side-by-side makes you realize why the ZR1 costs what it does for what it can do.
Although not really mentioned in the forum post is the naturally aspirated 460-horsepower C7 Grand Sport which is said to have run a 2:45 by Jim Mero during testing back in 2016. Again, that’s a hell of a lot of performance for nearly half the money of the ZR1. So Corvette buyers have plenty of options with the only qualifiers being “how fast do you want to go” and “how much do you want to spend.”
It’s further proof that we are living in the gilded age of horsepower.
Here are the full videos from which the screen shots were produced:
