vdiv, perhaps you can remind us how much the McLaren P1, Porsche 918 Spyder, and Ferrari SF90 Stradale cost in comparison? The Corvette, at least since the C5, is about big bang for your buck. It was never intended to beat the world in every possible way. That would be impossible at its price point. Yeah, I do feel sometimes like a defender of the make since my C5 was such a great car in so many ways ("leaf springs?").
There is also some tradition inertia over specifically the Corvette. The C8 was polarizing to the existing ownership community when it was first announced. This is another big step forward for the platform. AWD is a huge first for it. Getting rid of a V8 engine entirely is another leap for some of the intended audience.
