The Chevrolet Vega is a subcompact automobile manufactured and marketed by GM's Chevrolet division from 1970 until 1977. Available in two-door hatchback, notchback, wagon, and sedan delivery body styles, all models were powered by an inline four-cylinder engine designed specifically for the Vega, with a lightweight aluminum alloy cylinder block. The Vega first went on sale in Chevrolet dealerships on September 10, 1970.[1] Variants included the Cosworth Vega, a short-lived limited-production performance version introduced spring 1975. The Vega received the 1971 Motor Trend Car of the Year. Subsequently, the car became widely known for a range of problems related to its engineering,[4] reliability,[5] safety,  propensity to rust, and engine durability. Despite numerous recalls and design upgrades, Vega's problems tarnished its reputation and that of General Motors. Production ended with the 1977 model year
