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.
