Alfa Romeo 8-cylinder F1 engine

Alfa Romeo has made three 8-cylinder Grand Prix racing engines designed for Formula One; in both inline and V engine configurations. Their first was the supercharged 158/159, a straight-eight engine, with the 1.5 L engine configuration imposed by the FIA for forced induction engines, in 1950.[2][3] After a 20-year gap, their second engine was the Tipo 33 engine, a 3-liter naturally-aspirated V8 engine, in 1970. Their third and final engine was the turbocharged 890T V8 engine in 1983, which was used by both Alfa Romeo until 1985, and Osella until 1988, until Alfa Romeo eventually pulled out of F1 that same year.[4][5]
