Chevrolet Corvette Generations
The first generation Corvette was introduced late in the 1953 model year. Originally designed as a show car for the 1953 Motorama display at the New York Auto Show, it generated enough interest to induce GM to make a production version to sell to the public. First production was on June 30, 1953.
This generation was often referred to as the "solid-axle" models (the independent rear suspension was not introduced until the second generation). 300 hand-built polo white Corvette convertibles were produced for the 1953 model year.
The second generation (C2) Corvette, which introduced Sting Ray to the model, continued with fiberglass body panels, and overall, was smaller than the first generation. The C2 was later referred to as mid-years. The car was designed by Larry Shinoda with major inspiration from a previous concept design called the "Q Corvette," which was created by Peter Brock and Chuck Pohlmann under the styling direction of Bill Mitchell. Earlier, Mitchell had sponsored a car known as the "Mitchell Sting Ray" in 1959 because Chevrolet no longer participated in factory racing. This vehicle had the largest impact on the styling of this generation, although it had no top and did not give away what the final version of the C2 would look like. The third inspiration was a Mako Shark Mitchell had caught while deep-sea fishing.
Production started for the 1963 model year and ended in 1967. Introducing a new name, "Sting Ray", the 1963 model was the first year for a Corvette coupe and it featured a distinctive tapering rear deck (a feature that later reappeared on the 1971 "Boattail" Buick Riviera) with, for 1963 only, a split rear window. The Sting Ray featured hidden headlamps, non-functional hood vents, and an independent rear suspension.
The third generation Corvette, patterned after the Mako Shark II concept car, was introduced for the 1968 model year and was in production until 1982. C3 coupes featured the first use of T-top removable roof panels. It introduced monikers that were later revived, such as LT-1, ZR-1, Z07 and Collector Edition. In 1978, the Corvette's 25th anniversary was celebrated with a two-tone Silver Anniversary Edition and an Indy Pace Car replica edition of the C3. This was also the first time that a Corvette was used as a Pace Car for the Indianapolis 500.
Engines and chassis components were mostly carried over from the C2, but the body and interior were new. The 350 cu in engine replaced the old 327 cu in as the base engine in 1969, but power remained at 300 bhp. 1969 was the only year for a C3 to optionally offer either a factory installed side exhaust or normal rear exit with chrome tips.
The fourth generation Corvette was the first complete redesign of the Corvette since 1963. Production was to begin for the 1983 model year but quality issues and part delays resulted in only 43 prototypes for the 1983 model year being produced that were never sold. All of the 1983 prototypes were destroyed or serialized to 1984 except one with a white exterior, medium blue interior, L83 350 ci, 205 bhp V8, and 4-speed automatic transmission.
Regular fourth generation production began on January 3, 1983; the 1984 model year and delivery to customers began in March 1983. The 1984 model carried over the 350 cu in L83 slightly more powerful "Crossfire" V8 engine from the final 1982 third generation model. New chassis features were aluminum brake calipers and an all-aluminum suspension for weight savings and rigidity. The new one piece targa top had no center reinforcement. A new electronic dashboard with digital liquid crystal displays for the speedometer and tachometer was standard. Beginning in 1985, the 230 bhp L98 engine with tuned port fuel injection became the standard engine.
Production of the C5 Corvette began in 1997 and ended with the 2004 model year. The C5 had a top speed of 181 mph and was judged by the automotive press as improved in nearly every area over the previous Corvette design with the inclusion of a torque tube and rear transaxle along with the car's much increased structural rigidity and much more curvaceous design.
Also introduced with the C5 was GM's new LS1 small block. This third-generation small block V8 was completely redesigned. Now all-aluminum, it featured a distributor-less ignition and a new cylinder firing order.
The C6 Corvette retained the front engine and rear transmission design of the C5, but was otherwise all-new, including new bodywork with exposed headlamps (for the first time since 1962), a larger passenger compartment, a new 6.0 liter engine and a reworked suspension geometry. It had a longer wheelbase than the C5, but its overall vehicle length and width were less than the C5.
The new Z06 arrived as a 2006 model in the third quarter of 2005. It has a 7.0 L version of the small block engine codenamed LS7. At 427.6 cubic inches, the Z06 was the largest small block ever offered from General Motors. Because of the Corvette's former use of 427 cubic-inch big blocks in the late-1960s and early 1970s, the LS7's size was rounded down to 427 cubic inches.
The next-generation (C7) Corvette had been in development since 2007. Originally set to be introduced for the 2011 model year, its introduction was delayed for 3 years. It was finally released for the 2014 model year. Mid-engine and rear-engine layouts had been considered, but the front-engine, rear-wheel drive platform was chosen to keep production costs lower.
To GM's product planners and marketers, the fact that the Corvette had become known as an "old man's toy" became a prime factor in developing the next generation. Studies showed that about 46 percent of Corvette buyers in 2012, through October, were 55 or older, compared with 22 percent of Audi R8 and 30 percent of Porsche 911 customers. The head of Chevy marketing, Chris Perry, acknowledges that too many people saw it as the car of "the successful plumber." John Fitzpatrick, Corvette's marketing manager said "It's the old saying, 'Nobody wants to be seen driving an old man's car, but everybody wants to be seen driving a young man's car.' " To counter that perception GM planned to make the new generation C7 more aspirational to younger people. Towards that end, a camouflaged version of the car was made available in the popular video game Gran Turismo 5 in November 2012. As part of the marketing effort associated with the introduction of the new generation, the 2013 Indianapolis 500 utilized a Corvette for the 12th time as its pace car. Pace car editions are planned.
