The Chevrolet Matiz, produced from 2000 to 2005, represents the M100/M150 first generation of this city car. Engineered as an economical and practical subcompact hatchback, it was designed for urban commuting and budget-conscious buyers, competing with models like the Hyundai Atos and Kia Picanto. Its compact dimensions, approximately 3,495 mm in length and 1,495 mm in width, make it highly maneuverable in congested city environments. The Matiz typically features a 796cc inline 3-cylinder engine, often paired with a 5-speed manual transmission or an optional 3-speed automatic, delivering efficient performance for its class.
