I, too, believe this is the blue interior. On another thread here, most people believe this is the new dark gray.2015 Chevrolet Corvette Z06 Convertible Photos and Info ? News ? Car and Driver
I am not sure but I think that is the blue interior and maybe the new spectra wheels?
I agree with John. Having this in my LB Z06, it is the dark gray interior. I have the Blue Diamond interior in my 60th 427 Vert, and it is a dark blue (never mistaken for gray).Confirmed from it's Chief Interior Designer, Ryan Vaughan, that while pictures can, and sometimes give it a somewhat "bluish" appearance, it is "a pure gray when you see it in person."
Have seen it in person several times, and it is a medium/dark gray!
