Corvette stingray 1973
The Corvette is a classic car that have survived into its 6th generation as one of GMs truely iconic cars. Corvettes have been rolling on the streets since the early 1950s when the first Corvette was designed by legendary engineer and automotive stylist Harely Earl.
The six generations all contained different versions and are commonly referred to as C1 -C6. The latest generation does for instance include the ZR1 model; a car fitted with the most powerful engine ever used in a production Corvette.
One of the most loved and appricated models is the Corvette Stingray, which is a C2 Corvette with a split rear window and purely decorativ hood vents. The stingray was produced from 1963-67 and featured independent rear suspension wis was rare for the day. Only the first year model featured the distinct split window and hood vents which were then removed due to the fact that Zora Arkus-Duntov, High performance director, didn’t like the design.
The latest version of the Corvette is the C6 ZR1 which is a juiced up high performance version of the regular 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. It was also appointed “2009 Performance Car of the Year by Top Gear” and has done the N¼rburgring Nordschleife lap 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. A special pain treatment safeguards the carbon fibre from being damaged by the sun. The designers did a good job in reducing the weight of this care and it weighs a mere 1520 kg (3352lb).
All this power must naturally be combined with potent braking capacity so the ZR1 has been fitted with breaks originally designed for Ferrari. Ferrari developed the ceramic break system to use on their epic Ferrari Enzo, a limited edition tribute to Ferrari Enzo who founded Ferrari. The Corvette ZR1 will stop in less than 30 meters (96ft) at 96 km/h (60mph).
