The 2015 Chevrolet Corvette Z06 Convertible, has an aluminum structure that's 20 percent stiffer than the previous, fixed-roof Z06 and has a thick fabric top, offered in four colors along with sound-absorbing padding and a glass rear window which contributes to a quiet cabin. The Z06 convertible features an electronic top that can be lowered remotely using the car’s key fob. The top can also open or close on the go, at speeds of up to 30 mph. Like the Corvette Z06 hardtop, the convertible has the all-new LT4 6.2L supercharged V-8 engine with at least 625 horsepower, and 635 pound-feet of torque mated to a standard seven-speed manual transmission with Active Rev Match, or an all-new 8L90 eight-speed paddle-shift automatic transmission.
