Utterly stunning, the 2015 Chevrolet Corvette Z06 is the company’s fourth-gen supercar, with a 6.2-liter V8 supercharged engine that will deliver 625-hp. At least. Opt for a 7-speed manual or an all-new eight-speed automatic transmission, with upshifts even faster than those of the 911. Chevy’s active fuel management system will keep your gas mileage somewhat reasonable, but, we guess if you’re driving around in one of these things, you’re not really going to be too concerned about that.
