The Chevrolet Vega was a series of subcompact cars that debuted for the 1971 model year. This family of rear wheel drive cars was available in a range of body styles, including notchback, hatchback, and station wagon. Over the course of production, the Vega's styling received regular updates, while the engine remained largely the same. The 2.3L inline four unit received an update in 1976, but the most notable engine available on the Vega was the 2.0L inline four unit available in the Cosworth Vega. This limited production performance car featured an exclusive engine that was developed by legendary engine builders Cosworth Engineering. Chevrolet built the Vega until 1977.
