Days after Chevy released its first teaser, spy shots of the new 2015 Chevrolet Corvette Z06 have hit the wire, showing dramatic aerodynamic enhancements, extra vents, and a new hood - which just may be hiding a new 650-hp supercharged V-8 underneath, according to a leaked Instagram photo.

Despite the fact that it's well camouflaged, this 2015 Chevy Corvette Z06 prototype gives away most of its tells up front. The 'Vette's front bumper appears to be heavily reworked, with a larger grille opening flanked by aerodynamic enhancements on either side. Knowing Corvette designer Kirk Bennion's functional design mantra, we're willing to bet those add a decent amount of downforce.

The 2015 Corvette Z06's hood also looks significantly revised, with a distinctive power dome. Rumor has it that underneath the bulge is a supercharged version of the 2014 Corvette Stingray's LT1 6.2-liter V-8. Supporting this rumor is an Instagram photo by American Velocity Performance, which shows the alleged engine on an engine stand. Dubbed the LT4, the supercharged 6.2-liter V-8 supposedly makes between 600- and 650-hp. The power dome on the hood would allow for increased clearance of the supercharger, as well as for its associated piping and cooling hardware.

That's not the whole story though. The rear-quarter panel now sports an added cooling vent ahead of the wheel, like the brake cooling duct found on the C5 Corvette Z06. As seen in the teaser, the Corvette Z06's rocker panel certainly looks more aggressive too. We wouldn't be surprised to see a few tweaks done to the Stingray's rear in Z06 trim.

The 2015 Chevrolet Corvette Z06 will debut early next month at the North American International Auto Show in Detroit.
