We were already impressed with the crazy fast Corvette Z06 which even had American car hater Clarkson from Top Gear praising it. Well now new spy shots confirm the Chevrolet is testing the Corvetter Z06-R which is expected to produce at least 600 horsepower. The current Corvetter Z06 has a 7 liter engine that produces 500 horsepower. From the spy shots you can see a little hood scoop, which the photographer says could be holding a supercharger.
