2013 C6 Chevrolet Corvette ZR1
The 638-hp, 6.2-liter supercharged V-8 LS9 engine features such niceties as titanium connecting rods and intake valves, a forged steel crankshaft, and a dry-sump oil system. The suspension has magnetorheological shocks that enabled Chevrolet engineers to use softer springs than in the conventionally damped Z06. Corvette's top dog model is no joke and an accomplished sports car that puts up a good fight against the world's best.
The 2005-2013 Callaway Corvette was a specialist version of the C6 Corvette, built by Callaway Cars expert craftsmen and sold through selected Callaway/Chevrolet dealers. The 17th “C-Project” undertaken by Callaway first produced naturally-aspirated SuperNatural™ 450, 461, 490 (6.0L) and 550 (6.8L & 7.0L) horsepower Callaway Corvettes. In February 2006, Callaway returned to its positive manifold pressure roots, introducing Callaway “SuperCharged” Corvettes.
The Callaway C16 was Callaway’s 16th major automotive project. It was a limited production, bespoke automobile, built to order, by what the Press called “the best specialist engineers in the business”. These cars are seriously fast, beautiful, and exclusive. The C16 was a direct competitor for the Porsche GT3, the Lamborghini Murcielago, the Ferrari 599 GTB. It was both faster and more capable than its competitors, at less cost.
2009 Chevrolet Corvette ZR1
The ZR-1 returned with the 1990 Corvette lineup after an eighteen year hiatus.  This time, it featured a special LT5 engine that had been developed by Lotus (which, at the time, had been a subsidiary of General Motors.) The LT5 engine featured an all-aluminum block, four overhead camshafts, and 32 valves. It also featured an air management system which enabled the car to maintain proper operation while closing off half of its fuel injection system.
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.
