The Chevette originally appeared with a 1.4-liter inline-four of Isuzu origins, albeit with a single overhead cam rather than the pushrod model originally used in the United States. In 1981 this was augmented by a locally developed 1.6-liter version, it too with a single carburetor. The Brazilian 1.6 was somewhat larger than the Isuzu-developed G161Z engine used in North America. For 1988, the 1.6 gained a twin-carb setup and now produced rather than the in earlier version. This engine remained available until the end of Brazilian Chevette production. The lower-powered 1.4 was only available for gasohol as of 1981 and was discontinued entirely after 1982. A gasohol-powered version of the 1.6 appeared in its stead for 1983.
