MotorTrend has an article talking about the C8 Corvette E-Ray possibly being faster then the C8 Corvette Z06. However, its kind of misleading because possibly it will be faster from a launch from 0 to 60 with hybrid assist motors in the front similar to an Acura NSX.
It will most likely not be faster than a C8 Corvette Z06 overall but perhaps faster then the base C8 Corvette Stingray Z51 base model.

A YouTuber that covers most of the corvette news found on Corvette Blogger or other automotive blogs like ours HorsePower Obsessed covers this story as well as the C8 Corvette wheel issue and possibly a new C8 Corvette SUV that Chevrolet and General Motors is working on.
