The GM Family I is a straight-four piston engine that Opel developed, back when it was a General Motors subsidiary, to replace the Vauxhall OHV, the Opel OHV and the smaller Opel CIH engines in small and mid-range Opel and Vauxhall cars. It first appeared in the Opel Kadett D in 1979 and in the Vauxhall Astra Mk.1 in 1980, although the older Opel OHV engine stayed in entry-level Kadetts, Astras and Corsas through the 1980s. It is informally called the small block because it shares its design and architecture with the larger Family II, the large block. It has belt-driven single or double overhead camshafts in an aluminum head on a cast iron block. It was built at Aspern in Austria, then at Szentgotthard in Hungary once the DOHC version arrived, and also by GM do Brasil, GMDAT in Korea and GM North America at Toluca; Brazilian versions could run on ethanol. Early engines gained a bad name for camshaft and follower failures.
