.The Chevrolet Vega is a subcompact automobile produced by the Chevrolet division of General Motors from 1970 to 1977. Named after the star Vega, GM's first U.S. mini-car was produced in two-door hatchback, notchback, wagon, and panel delivery body styles all featuring an inline four-cylinder engine with a lightweight, aluminum alloy cylinder block.
Initially well-received by buyers and the motoring press, the car sold well against the AMC Gremlin and Ford Pinto subcompacts and imports including Toyota, Datsun and Volkswagen. By 1974 it was among the top ten best-selling American cars.
The Cosworth Vega, a short-lived limited-production performance model with a reduced-displacement but more powerful all-aluminum inline four-cylinder engine, was introduced in March 1975.
In early Vegas, engine problems and fender corrosion harmed GM's reputation for build quality. The faults were remedied by recalls and design upgrades. A three-year sales decline led to the car's cancellation at the end of the 1977 model year
The Vega was conceived in 1968 to utilize newly developed all-aluminum die-cast engine block technology -- the first sand-cast aluminum blocks had preceded the decision to build the car by two years. A relatively large displacement engine with good low- speed torque was decided on. gear ratios for low engine rpm would achieve economy. Engine testing totalled 6,000,000 miles. The pre-test version was installed in a Fiat 124 sedan for development of the aluminum block, while several 1968 Opel sedans were used for drive train development
Chevrolet instituted a new management program, the car line management technique, which made it possible to produce the all-new car in two years. The chief vehicle engineer had overall charge of the program. 50 engineers, dedicated to the design of the entire car, were divided into groups: body, power train, chassis design, product assurance, and pleasability. The latter would check continuously on the vehicles on the assembly line, with computers in another program monitoring quality control of every vehicle built. Fisher Body engineers and draftsmen moved in with the Vega personnel.
In October 1968, there was one body style (the "11" style notchback sedan), one engine, one transmission (MB1 Torque-Drive manually shifted two-speed automatic), one base trim level, a bench seat, molded rubber floor covering, no glove box or headliner and no air-conditioning (ventilation was through the upper dash from the wiper plenum). As the program went into development, the market changed, as did the product.
December 1968: Hatchback, wagon, and panel delivery styles added; also floor-level ventilation, and an optional performance engine ("L-11" two-barrel) which, predicted as 20% of production, accounted for 75%. Bucket seats were standard. Hatchback and station wagon received carpeting and headliners. Optional Air conditioning, predicted as 10% of production, rose to 45%.
February 1969: Opel three- and four-speed transmissions (three-speed standard, others optional); Powerglide also added (now four transmissions); mechanical fuel pump replaced by in-tank electric pump; power steering option; base "11" style Notchback trim upgraded to match Hatchback and Wagon carpet and headliner.
April 1969: Gauge-pack cluster, HD suspension, wide tires; adjustable seat back (45% of production); bumpers restyled, lower valance panels added; swing-out quarter window option (10% of production).
July 1969: Electrically heated backlite option (10% of production); "GT" package, $325.00 extra (35% of production); bright window-frame and roof drip moldings added to Hatchback and Wagon.
This is essentially how the car launched as a 1971 model. Production began on June 26, 1970. After the National GM strike (September to November 1970) ended, bright roof drip moldings were added to base "11" notchback, with moldings sent to dealers to update units already in the field.
Cars magazine said in 1974: "Chevrolet paid a price for its rush to introduce the car with other 1971 models. Tests which should have been at the proving grounds were performed by customers, necessitating numerous piecemeal "fixes" by dealers. Chevrolet's "bright star", received an enduring black eye despite a continuing development program which eventually alleviated most of these initial shortcomings
