It would be no surprise for GM to add a supercharger to the Corvette for some future variant. That's what they did to the current ZR1.
We've seen these supposed boost gauges in other photos of the new 'Vette, but these are possibly the best ones we've found yet.
We're just dreaming of twin turbos. What do you think these gauges imply?
