Chevrolet Corvette


 

  The Chevrolet Corvette is a sports car by the Chevrolet division of General Motors that has been produced in six generations.

The first model, a convertible, was designed by Harley Earl and introduced at the GM Motorama in 1953 as a concept show car. Myron Scott is credited for naming the car after the type of small, maneuverable warship called corvette.

Originally built in Flint, Michigan and St. Louis, Missouri, the Corvette is currently built in Bowling Green, Kentucky and is the official sports car of the Commonwealth of Kentucky. The National Corvette Museum documents the car's worldwide history and hosts the annual event.



  The first generation Corvette was introduced late in the 1953 model year and ended in 1962. Often referred to as the "solid-axle" models because the independent rear suspension did not debut until the 1963 Sting Ray.

300 hand-built polo white Corvette convertibles were produced for the 1953 model year.

The 1955 model offered the 265 cu in (4.34 L) V8 engine as an option; however, the first seven off the production line featured the standard "Blue Flame" Inline-6.

  The origin of the Chevrolet Nomad was a two-door wagon concept car built off a 1954 Corvette. Early production Corvettes were fitted with the Chevrolet Powerglide two-speed automatic transmission.

A new body was introduced for the 1956 model featuring a new "face" and side coves; the taillamp fins were gone. An optional fuel injection system was made available in the middle of the 1957 model year.

  It was one of the first mass-produced engines in history to reach 1 bhp (0.75 kW) per cubic inch (16.4 Cubic cm) and Chevrolet's advertising agency used a "one hp per cubic inch" slogan for advertising the 283 bhp (211 kW) 283 cu in (4.64 L) Small-Block engine.

Other options included power windows (1956), hydraulically operated power convertible top (1956), four speed manual transmission (late 1957), and heavy duty brakes and suspension (1957).




   The second generation smaller Corvette with I.R.S. was called a Sting Ray & later referred to as mid-years. Designed by Larry Shinoda with major inspiration from a previous concept design called the "Q Corvette" by Peter Brock and Chuck Pohlmann under the styling direction of Bill Mitchell. The design had several inspirations.

Mitchell 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 coupe 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 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. Duntov never liked the split rear window because it blocked rear vision, but Mitchell thought it to be a key part of the entire design. Maximum power for 1963 was 360 bhp (270 kW) and was raised to 375 bhp (280 kW) in 1964.

Options included electronic ignition, the breakerless magnetic pulse-triggered Delcotronic first offered on some 1963 Pontiac models. On 1964 models the decorative hood vents were eliminated and Duntov got his way with the split rear window changed to a full width window.




 

 The third generation Corvette, patterned after the Mako Shark II concept car, was introduced for the 1968 model year and lasted 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, and Collector Edition. The Corvette's 25th anniversary was celebrated in 1978 with a two-tone Silver Anniversary Edition and an Indy Pace Car replica edition.

It was 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 (5.7 L) engine replaced the 327 cu in (5.36 L) as the base engine in 1969, but power remained at 300 bhp (224 kW). 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 all-aluminum ZL1 engine was new for 1969.The special big-block engine was listed at 430-hp (320 kW), but was reported to produce 560 hp (420 kW) and propelled a ZL1 through the 1/4 mile in 10.89 seconds 



   The fourth generation Corvette was the first all-new Corvette since 1963. Production was to begin for the 1983 model year but quality issues and part delays resulted in only 44 1983 model prototypes being produced that were never sold. All of the 1983 prototypes were destroyed except one with a white exterior, medium blue interior, L83 350 ci, 205 bhp V8, and 4-speed automatic transmission.

After extensive testing and modifications were completed, it was initially retired as a display sitting in an external wall over the Bowling Green Assembly Plant's employee entrance. Later this only surviving 1983 prototype was removed, restored and is now on public display at the National Corvette Museum in Bowling Green, Kentucky. It is still owned by GM.

Regular fourth generation production began on January 3, 1983 as the 1984 model year and delivery to customers began in March 1983.

The 1984 model carried over the 350 cu in (5.7 L) L83 slightly more powerful (5 bhp) "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 (170 kW) L98 engine with tuned port fuel injection was the standard engine.



   Production of the C5 Corvette began in 1997 and ended with the 2004 model year.

Chevrolet used cars like the Nissan 300ZX and Mazda RX-7 as benchmarks for quality and styling due to criticisms the C4 Corvette received when compared to Japanese rivals.

 The C5 had a top speed of 181 mph (291 km/h) and was judged by the automotive press as improved in nearly every area over the previous Corvette design thanks to its much improved 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 features a distributor-less ignition and a new cylinder firing order.

  It was initially rated at 345 bhp (257 kW) and 350 lb·ft (470 N·m), but was increased to 350 bhp (260 kW) in 2001. The new engine, combined with the new body and its low 0.29 drag coefficient, was able to achieve up to 28 mpg on the highway.


 

 
   The C6 Corvette retained the front engine – rear transmission design of the C5, but was 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 has a longer wheelbase than the C5, but overall vehicle length and width are less to gain wider appeal to the European market. The 6.0L (364 cu in) LS2 V8 produced 400 bhp (300 kW) at 6000 rpm and 424 lb·ft (575 N·m) at 4400 rpm, giving the vehicle a 0–60 time of under 4.2 seconds.

  The C6 generation comes close to retaining the relative good fuel economy of the C5, due in part to its relatively low .

28 drag coefficient and low curb weight, achieving 16/26 mpg (city/highway) equipped with automatic or manual transmissions; like all manual transmission Corvettes since 1989, it is fitted with Computer Aided Gear Selection (CAGS) to improve fuel economy by requiring drivers to shift from 1st gear directly to 4th in low-speed/low-throttle conditions
