Designed by Aurelio Lampredi, the Fiasa engine first appeared in the Brazilian-built Fiat 147 in September 1976, and shortly afterwards in the 'Series 2' version of the Fiat 127. The name Fiasa is a portmanteau of "Fiat Automóveis S.A.", for whom it was developed. The in-line four-cylinder engine has five main bearings, a cast iron block with an aluminium cylinder-head with belt-driven overhead camshafts actuating the valves. The engine remained in production until 2001 in Latin America, and also provided the basis for a diesel version (never sold in Brazil, where it was built, as that country did not allow diesel passenger cars). The capacity was initially 1.0 L (1,049 cc), but Lampredi designed the engine to be suited for a considerably longer stroke. Sizes eventually ranged between 1.0 and 1.5 L (994 and 1,497 cc). The last versions of this engine to be built was a 1.5-litre, dedicated-ethanol version developed in Brazil that served the Fiat Uno and its derivatives, and later yet the Fiat Palio (both the hatch and the Weekend) until 2001.
