Update: Added 21 additional spy photos to a new photo gallery showing C8 Corvette ZR1 prototypes in action at the Nurburgring.

The next-generation Chevrolet Corvette in ZR1 trim hasn’t exactly been a secret so far. We’ve already seen several heavily camouflaged prototypes testing in different locations around the United States. However, it seems that the automaker is now moving the development to the Old Continent. At least two different prototypes were recently caught testing on the famous Nurburgring race track.
