Chevrolet Vega . Introduced September 1. Vega 2. 30. 0, its name came from a bright star in the northern skies and the engine's approximate displacement in cubic centimeters. Designed from scratch in twenty four months by a team of 5. GM corporate engineers assigned exclusively to the program, the Vega was available in four models: a notchback sedan, a hatchback coupe, a station wagon, and a panel delivery (thru 1. All have two doors and hold four passengers, with the exception of the panel delivery which is designed for one passenger. The Vega engine is a 1. CID (1. 39. 6 cu in) aluminum- block OHC inline- 4. The Vega competed directly with its domestic rivals from Ford and AMC and imports from Toyota and Datsun as well as the rear- engined VW Beetle. Conservative estimates had placed the cost of bringing the Vega from drawing board to production reality at a staggering $2. AMC Gremlin. Motor Trend awarded the Vega 1. The one- millionth Vega was produced May 1. The Vega was among the top 1. American cars in 1. The Cosworth Twin- Cam, a limited production, performance model was introduced in March 1. CID (1. 21. 7 cu in) all- aluminum inline- 4, the 1. DOHC cylinder head design by Cosworth Engineering in England. Vega sales in 1. 97. CID engine while the Vega- derived Monza and smaller Chevette provided alternatives. By 1. 97. 6, the Vega had received five years of improvements (3. Despite the continuous development program and efforts to improve the car's image, Chevrolet cancelled the Vega and its aluminum engine at the end of the 1. Vega built, June 2. Chevrolet and Pontiac divisions were working separately on small cars in the early and mid 1. Ed Cole, GM's executive vice- president of operating staffs was working on his own small- car project using the corporate engineering and design staffs. He presented the program to GM's president in 1. When the corporation started seriously talking about a U. S. Not only did corporate management make the decision to enter the mini- car market, it also decided to develop the car itself. It was a corporate car, not a divisional one. Ed Cole was the chief engineer and Bill Mitchell, the vice- president of the design staff, was the chief stylist. Cole wanted a world- beater, and he wanted it in showrooms in twenty- four months. This was a brutally short time to design and engineer a new car, especially one that borrowed almost nothing from any other. He formed a GM corporate design team exclusively for the Vega headed by James G. Musser said, . It was as GM president that Cole oversaw the genesis of the Chevrolet Vega. Early spy reports called the Vega . The first sand cast aluminum blocks were actually produced a full two years prior to the corporate decision to build the Vega. A relatively large displacement engine with good low speed torque was chosen. Economy would be achieved through the use of low numerical gear ratios, which would keep engine rpm low. The Vega engine itself went through 6,0. The earliest version of the engine was tested in a Fiat 1. This car was used for development of the aluminum block, while several 1. Opel sedans were used for drive train development. General Motors instituted a totally new management program to design the Vega: the car line management technique. In placing a single individual, the chief vehicle engineer in charge of the entire program and having the entire car – including engine, suspension, and brakes – designed by engineers specifically assigned to the Vega. A total of fifty engineers were assigned to the Vega engineering team broken down into body, power train, and chassis design groups, the product assurance group, and the pleasability group. Fisher Body engineers and draftsmen were also moved in with the Vega personnel. It is generally acknowledged that this organizational arrangement made it possible to put out a totally new car in such a short time. The pleasabilty group would check continuously on the vehicles on the assembly line. As part of another program, computers would keep tabs on quality control of every vehicle built. At the very beginning of the experimental engine program at GM engineering staff, Ed Cole stated in a meeting that there would probably be no need for a traditional radiator, due to the excellent heat rejection to the air from the aluminum block. He felt that coolant could simply be passed through the heater core, with outside air ducted through the core and exhausted under the car to provide auxiliary cooling. Several pre- prototype cars were built this way at his insistence, and all of them were dismal failures from a cooling perspective. After having one seize up while he was driving it at the Milford proving grounds one Saturday, he backed away from his theory and allowed the design to continue with a conventional cooling system. He requested provisions for V8 engine, a full- line of body styles and consideration of a two- passenger coupe version. As the program progressed into development, the market changed, and so did the product. December, 1. 96. 8 – Hatchback, wagon, and panel delivery styles added. Bucket seats replaced bench seat as standard equipment. Carpeting and headliners added for hatchback and station wagon. Air Conditioning option added; predicted production was 1. This is essentially how the car launched as a 1. After the National GM strike (9/7. The car still had no glove box. With its lower roof line and useful fold- down rear seat, it accounted for nearly half of all Vegas sold. Road & Track, September 1. Vega coupe has roof, window, and deck forms extremely- and not accidentally- similar to those of the Italian luxury car. An auxiliary front passenger seat was optional. Classified as a truck, the panel has 6. Road & Track, January 1. By us, it's a 2- place square- back Vega coupe, with room for just about everything and anything that two people would want to go anywhere with. Sport stripes in black or white were available. Motor Trend, August 1. Gurney said: . I like it; I like it very much. Everything about it was cutting- edge: it featured a lightweight aluminum engine block and sporty European suspension tuning, and the factory where it was built was the fastest and most automated in the world. GM even rolled out a brand new shipping method, Vert- A- Pac – hanging Vegas vertically in specially designed railroad freight cars. One of GM's proudest boasts about the Vega was that it was the most . It's entire design hinged upon its ability to be built rapidly with as much machine labor (instead of human) as possible. This was the only way GM could sell the car at a price competitive with imported cars made with cheaper labor rates. In February 1. 97. Road & Track warned, . The 1. 97. 1–1. 97. In a size comparison with a 1. Nova, the Vega has a 1. As introduced, the Vega was one of the first Chevrolet vehicles to have as standard equipment front disc brakes, an electric fuel pump, side guard door beams, a double paneled roof, and foam- filled, hi- back bucket seats with floor mounted controls. Safety regulations and crash tests resulted in the Vega being nearly 3. However, a part of the penalty was caused by the decision to use 3. The standard acoustical package added another 3. The aluminum block inline- four engine was a joint effort from General Motors, Reynolds Metals, and Sealed Power Corp. The engine and its die- cast block technology was developed at GM engineering staff long before the program was handed- off to Chevrolet to finalize and bring to production. L4 engine,3- speed manual. Ed Cole, who had been very personally involved with the design of the 1. Chevrolet V8 as chief engineer at Chevrolet, was equally involved with the Vega engine as GM president, and was a frequent visitor on Saturdays to the engineering staff engine drafting room, reviewing the design and giving direction for changes. Chevrolet engineers and manufacturing personnel weren't pleased, especially since they knew Ed Cole wanted the job done quickly. As the engine development progressed at Chevrolet, it became known (in closed offices) as . Plagued by vibrations, noisy operation and prone to overheating, the engine did not live up to the Vega's potential. By 1. 97. 4, the overheating and vibrations were a thing of the past and the noise had been reduced to an acceptable level. The GM finance department insisted that the base transmission be a low- cost three- speed, with the traditional profit- generating four- speed as an extra- cost option. Opel did just that, and tooled up a new 3- speed from scratch just for the Vega application, unusual only because it had shift linkages on both sides. Its final cost was higher than the optional four- speed due to the tooling investment and production volume. Both transmissions were shipped from Germany, 1. Initially Powerglide automatic and Torque- Drive semi- automatic transmissions were optional. The two- speed Torque- Drive required a manual upshift but had no clutch pedal. In 1. 97. 3 the U. S.- built Saginaw three- and four- speed manual replaced the Opel- built manual transmissions, and the Turbo- Hydramatic had replaced the Torque- Drive and Powerglide. Axle ratios ran from a low 2. Positraction was also available. Lateral acceleration capacity is . RPO F- 4. 1 suspension. Weight distribution is quoted at 5. The overall chassis suspension was to be tuned to a new A7. The front suspension is classic General Motors short and long- arm. The lower control arm bushings were actually larger than those of the 1. Camaro. The four- link rear suspension copied that of the 1. Chevelle, and coil springs are used throughout. This was a significant departure from the leaf spring suspension used in the Camaro and Chevy II Nova. The engineers in charge of chassis development were seeking a package that would provide full- size domestic car ride qualities with handling equal to that of European cars. In 1. 97. 6, a torque- arm rear suspension was adopted, replacing the four- link design, thus eliminating the panic- braking induced rear wheel- hop. GMC Terrain Reviews, Ratings, Prices.
