Another article where Al O. claims that it could run the Ring as fast as a 911 GT3. My only question... why weren't the cameras always rolling when they were going for a fast lap?
Anyway....7:30ish seems realistic. Another member posted a video of the 2017 ZL1 and Z/28 Ring videos side by side and they were neck and neck until the Z/28 hit the wet. 7:25 doesn't seem realistic, however.
