7. 2014 Chevrolet Corvette Stingray Convertible
In order to expand the global outreach of its 2014 Corvette Stingray, Chevy introduced a convertible version of the sports car at 2013 Geneva Motor Show. Competing with million-dollar Bugattis, Ferraris, and Lamborghinis, the drop-top version of the Stingray features 6.2-liter V-8 engine that gives the output of 450 horsepower and 450 pound-feet of torque. Chevrolet says the new Corvette's aluminum frame is 57% stiffer and 99 pounds lighter than the outgoing model's steel frame. This means the convertible version needed no extra structural bracing for rigidity.
