The current-generation Chevrolet Corvette isn't exactly a car that was crying out for major improvements. When the latest, redesigned model (the "C7") debuted last year, we heralded it as "the most complete and refined Corvette yet," with so much power that it's as if "Chevy secretly strapped a rocket engine underneath the car." But the 2015 Chevrolet Corvette lineup sees the new-generation Z06's debut -- in both removable-roof coupe and soft-top convertible forms -- and we fear we're running out of analogies. If the base 455-hp V8 is a rocket engine, the Z06's supercharged 650-hp V8 is akin to the solid rocket boosters that gave liftoff to the Space Shuttle. For thousands less than a base Porsche 911 with no options, the 2015 Corvette Z06 will outrun almost any car in the world. Learn more about the 2015 Chevrolet Corvette 3LT.
