The Chevrolet Corvette, known colloquially as the Vette or Chevy Corvette, is a sports car manufactured by Chevrolet. The car has been produced through seven generations. The first model, a convertible, was 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 a corvette. Originally built in Flint, Michigan and St. Louis, Missouri, the Corvette is currently manufactured in Bowling Green, Kentucky and is the official sports car of the Commonwealth of Kentucky.
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. 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. On February 12, 2014, it was nearly lost to a sinkhole which opened up under the museum. Eight other Corvettes were severely damaged.
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 (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 became the standard engine.
September 1984 through 1988 Corvettes offered a Doug Nash designed "4+3" transmission – a 4-speed manual coupled to an automatic overdrive on the top three gears. It was designed to help the Corvette meet U.S. fuel economy standards. Since 1981 (when it was last offered), a manual transmission returned to the Corvette starting with production in late 1984. The transmission proved to be problematic and was replaced by a modern ZF 6-speed manual transmission in 1989.
