For the 2014 model year, the Chevrolet team sculpted the seventh-generation Corvette into the most sophisticated, most feature-packed Corvette produced to date. Facing a daunting challenge, new technology enabled Callaway engineers to produce breathtaking power with seamless transition into and out of positive manifold pressure. Entirely new, Callaway’s patented GenThree supercharger design improved airflow quality and increased charge air cooling capacity.
2013 427 Collector Edition Convertible
The 2013 Corvette 427 Convertible served double-duty as a commemorative edition model.  While it marked the departure of the sixth-generation Corvette. The real selling-point was the powerplant at the heart of the car - a 427-cubic-inch (7.0L) LS7 engine, the same engine used in the C6 Corvette Z06.  Rated at 505 horsepower (377kW) and 470lb.-ft of torque (637 Nm), this 427 was the most powerful engine GM had ever installed in a production Corvette convertible to date.
While not exactly a "collector's edition" Corvette in its own right, it nonetheless has become a uniquely identifiable and collectible Corvette from the fourth-generation era. 1988 marked the 35th anniversary for Corvette, and so it was decided that Chevrolet should commemorate the milestone by introducing an anniversary-edition model. This anniversary car was the first of its kind in a decade, given that Chevrolet opted not to manufacture a Corvette in 1983.
Built exclusively for Hertz Rental Car, the Corvette ZHZ coupe was first introduced in 2008 as part of Hertz’s “Fun Collection.”  These Corvettes were part of a larger group of rental vehicles made up of cars like the Ford Mustang, the Nissan 350Z and the Shelby GT-H. The intent behind these rental cars was simple - provide consumers with an opportunity to rent (at a rate commensurate with the car's performance) a well-equipped sports car for a day, a weekend or even longer.
