XP-887 was an innovative design and engineering initiative that focused on the development of a high-volume, compact car program. It was initiated with the aim of creating a small car with advanced features. The fiberglass model of XP-887 was captured in photographs during the mid-1968 period. This project served as the cornerstone for Chevrolet's Vega program, laying the groundwork for the subsequent development and production of the Vega series of automobiles.
