Chevrolet just announced that the 2019 Corvette ZR1 is the fastest production car to lap the 4.1-mile Grand West Course at Virginia International Raceway with a time of 2:37.25.

The announcement comes conveniently less than a week after Car & Driver announced they had lapped a Ford GT around VIR's Grand West Course in 2:43.0, beating the Porsche 918 Spyder--and consequentially, the Viper ACR-- as the fastest car the publication has ever hustled around the legendary venue. 

Of course, there are key differences, for one, the Ford GT's lap was put down in a car Ford had brought down to VIR specifically for the publication, albeit with editorial talent behind the wheel. The ZR1's record lap at VIR was set during routine validation testing with vehicle dynamics engineer Jim Mero at the wheel as part of GM's 24 hours of at-the-limit track testing.
The car was set up as per the owner's manual for track duty, with a harness bar, track buckets, and a five-point harness fitted for safety. The car was equipped with the optional eight-speed paddle-shift transmission and ZTK Performance Pack which adds the adjustable carbon-fiber wing, massive front splitter, and Michelin Pilot Sport Cup 2 rubber.

"The track had been empty since mid-December, so it was a bit slow when we started, but the conditions turned pretty quick at the end," said Alex MacDonald, manager, Vehicle Performance. "On the heels of announcing our Z06 time of 2:39.77, the ZR1 lap time is the icing on the cake. It's not too often you set a lap record during validation testing."
