The Family 1 is a straight-4 piston engine that was developed by Opel, a subsidiary of General Motors to replace the Opel CIH engines for use on mid-range cars from Opel/Vauxhall. Originally produced at the Aspern engine plant, production was moved to the Szentgotthard engine plant in Hungary with the introduction of the DOHC version. GM do Brasil at São José dos Campos,GMDAT at Bupyeong and GM North America at Toluca also build these engines.

The Family 1 engines are inline-4 cylinder engines with belt-driven single or double overhead camshafts in an aluminum cylinder head with a cast iron engine block. GM do Brasil versions were also capable of running on ethanol. These engines are sometimes referred to as "Small-block" engines by enthusiasts; in contrast to the larger Family II engines which are sometimes referred to as the "Big-block" engines.

GM do Brasil specializes in SOHC, petrol-powered and FlexPower (powered with ethanol and/or petrol, mixed in any percentage) engines. GM Brasil also made 16-valve versions of the 1.0 engine. The 1.0 L 16v was available in the Corsa line-up from 1999 to 2001.
