The run in the video was the best one of three tries. The corvette advertised 0-60 time of 2.6 seconds must be on a specially prepared surface, with the best car they could build. It had Cup 2R tyres, while the GT had ”regular” Cup 2 tyres. It is not an easy car to get off the line.
I will admit, I was a little nervous going against it with these claims, but seeing It get beaten was quite satisfying. Primarily because some guy in a corvette hat literally yelled from the sidewalk, “I BEAT YOUUUU!!” as we were driving down PCH in Laguna Beach. That dude can go eat his hat, LOL.
