Corvette stingray
The Chevrolet Corvette is a General Motor sports car that now celebrates its sixth generation. The first corvette was designed by Harely Earl (the legend) and was introduced to the market during the 1950s.
The six generations, commonly referred to as C1 through C6, each come in multiple versions with different features. The C6 generation that is in production does for example include several models including the epic ZR1 which featured the strongets motor ever is in a Corvette.
One of the most famous Corvettes is the celebrated Corvette Sting ray, which is a C2 Corvette with a split rear window and purely decorativ hood vents. It was produced from 1963 to 1967 and featured independent rear suspension. The 1963 model was the only one with the distinct split window; Chevrolet director of high performance Zora Arkus-Duntov didn’t like the design and removed it from the coming models together with the non-functional hood vents.
In 2009 Corvette launched the C6 ZR1, a high performance version of the C6. Corvette used to be built in Flint, Michigan and St. Louis, Missouri, but the latest ZR1 version is built in Kentucky (Bowling green) with an engine built in Wixom, Michigan.
The ZR1 has recieved a very warm welcome by car critics. Iit was as an example namned the “2009 performance car” by the motoring show ” Top Gear a title it has proven itself worthy of by completing the nurburgring nordschleife in 7 minutes and 26.4 seconds.
The ZR1 engine produces 638hp (476kW), and 604foot-pounds (819Newton metres) of torque. Known as the LS9, the engine is a modified version of the LS3 and contains a sixth-generation Eaton TVS R2300 roots 4-lobe supercharger with intercooler. The supercharge and its output have been been designed not to change the appearance of the hood.
It is the first Corvette model ever to feature oil injectors that help reduce noise and improve cooling, the system also uses oil squirters tha make sure the pistons and cylinders always are well lubricated. Lubrication is also increased by a new and improved version of the dry sump system found on the LS7.
To cut down the weight, the chassis of the ZR1 Corvette is naturally made from aluminium just like the 2008 Z06, and the hood, roof, fenders, splitter, and rocker extension panels consist of carbon fibre. The carbon fibre have been specially treated not to be damaged by sunlight. The designers did a good job in reducing the weight of this care and it weighs a mere 1520 kg (3352lb).
A powerful car like the ZR1 need powerful breakes and the team therefore decided to use breakes designed by Ferrari. The rear brakes are the 14.5in (370mm) carbon ceramic rotors that were originally developed as front rotors for the Ferrari Enzo, while the front brake rotors feature a carbon ceramic design highly similar to the one found in the Ferrari FXX track car but10 mm smaller in diameter. At 60 mph (over 96 km/h), the ZR1 will stop within 96 feet (less than 30 meters).
