The Zagato company took a C7 Corvette Z06 and transformed it into the IsoRivolta GTZ, a "spiritual descendant" of the Iso Grifo A3/C (Corsa).  The original A3/C race car was developed by Giotto Bizzarrini not long after he left Ferrari, where he had served as cheif engineer behind the 250 GTO, which is revered as the world's most expensive car.  Bizzarrini purportedly fancied the A3/C as his "own personal evolution of (and improvement upon) the GTO design."
The L88 was a special option package developed under the direction of Zora Arkus-Duntov, director of GM’s performance division. First introduced in 1967, the L88 Corvette featured a highly modified version of Chevy’s 427-cubic-inch V-8 engine. Although this engine received a factory horsepower rating of 435, actual engine output was somewhere between 540 and 580 horsepower, giving the “stock” L88 enough power to run a quarter-mile in the high-11-second range!
There were only 20 Z06s produced with the Competition Sport package for worldwide purchase. This Z06 is powered by a 7.0-liter LS7 V8 engine producing 505hp and 424 ft/lbs torque, paired to the 6-speed manual transmission. The LS7 engine can propel this Z06 from 0-60 mph in 3.6 seconds. This Z06 CSR features leather interior, articulated sport seats, premium audio system, CD player and heads-up display.
The 2010 Grand Sport Corvette was introduced to the world at the 12th annual C5/C6 Corvette Birthday Bash, which was (and is) held at the National Corvette Museum in Bowling Green, Kentucky.  During its unveiling, it was announced that the new Grand Sport would be offered as either a coupe or a convertible, and it would feature an appealing combination of the LS3 power plant fused with the Z06 Corvette’s wide track chassis and styling features.
The Z06 arrived for the 2006 model year as a homologation vehicle in the third quarter of 2005 and is the lightest of all Corvette models. The Z06 was equipped with the largest-displacement small-block engine ever produced, a new 7,011 cc (7.0 L; 427.8 cu in) V8 engine codenamed the LS7. The engine has a power output of 505 hp and 470 lb⋅ft.
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.
