The Chevrolet Chevette was Chevrolet's version of General Motors's worldwide GM T platform of the 1970s, which was also sold as the Vauxhall Chevette, Opel Kadett, Isuzu Gemini and the Holden Gemini, among others. The T-car was actually first launched in Brazil under the Chevette name in 1974, as a two-door Sedan (car); the Brazilian Chevette line eventually included a 4-door sedan, a 3-door Hatchback, and a 2-door Station wagon (named Chevrolet Marajó), as well as a Pickup truck (named the Chevrolet Chevy 500), and was produced until 1994. Chevettes are also a car used in racing in Dirt Track Racing. It has its own series. The Chevette was the last Rear-wheel drive Subcompact for the United States and Canada, although in Mexico, it was last survived by the 2004 Volkswagen Beetle.
Production of the Chevette in the US started in late 1975 for the 1976 model year. Initially there was a 3-door Hatchback with 1.4 or 1.6 L OHC Gasoline Straight-4 engines, which varied over the years the Chevette was produced between 53-70 rear wheel horsepower. A 4-speed Manual transmission was standard, and a 3-speed Automatic transmission was optional. "Rally" or "Woody" option packages could be had, as well as a Loss-leader "Scooter" which was a 2-seater with painted instead of chromed bumpers and very basic trim inside and out. A rear seat was optional on the Scooter. The Canadian market also received a Pontiac version named the Acadian. Very early Chevettes can be identified by a hood that wraps down to the bumper, round headlights and a slightly curved tail with tri-color taillights rimmed in chrome.
The Chevette essentially replaced the Vega as Chevrolet's import-fighting small car. The Chevette was functional and inexpensive. It was the best-selling small car in America for the 1979 and 1980 model years. However, it lacked the technological advances bestowed on the Vega such as an aluminum engine, and it was based on the dated rear-wheel drive layout which dropped rapidly out of favor with the acceptance of the Volkswagen Rabbit.
The front-wheel drive Chevrolet Cavalier was launched upscale from the Chevette for the 1982 model year. The Chevette continued through the 1987 model year, when a version was offered at US $4,995 to compete with the Hyundai Excel and Yugo GV.
Beyond commuter duty
Being a cheap, lightweight, and readily available compact, Chevettes occasionally find their way into Dirt track racing or Drag racing, the latter of which will usually demand much more than the stock four cylinder would ever be capable of. The Chevette being rear wheel drive, and being compatible with many common GM components made the vehicle favorable to upgrade for racing and performance purposes where other compact cars were not. In Europe, where the Vauxhall Chevette HS was successful Rally car, a common swap is the lightweight Rover V8 engine V8 engine, requiring somewhat extensive fabrication. Common in the US and also requiring extensive fabrication is the GM 60-Degree V6 engine and the Chevrolet Small-Block engine. The GM Ecotec engine, is also suitable and can be fitted with sidedraft Weber carburetors in place of the engine's standard fuel injection system.
