The C7 ZR1 is an extension of the C7 Z06, which unlike the C6 Z06, was designed to be a coupe AND a convertible. So, what does that tell us about the engineering of the modern Corvette? MIGHTY IMPRESSIVE! The fact that the ZR1 convertible can handle 755-horsepower and 715 lb/ft of torque is astonishing.
Here’s an impressive tid-bit about the ZR1 convertible. The ONLY structural change between the ZR1 coupe and convertible is the re-positioning of the seat belts and the accommodations for the retractable top. And, the convertible only weighs 60-pounds more than the coupe, due to the mechanism for the convertible top.
