Giulio Alfieri (10 July 1924 – 20 March 2002) was an Italian automobile engineer, affiliated with Maserati in Modena, Italy since 1953, where he was central to the development of racing and production cars in the 1950s, 1960s, and 1970's.
Alfieri was born in Parma. After graduating the Politecnico of Milan, he first worked on steam turbines for the ship industry Cantieri Navali of Tirreno, in Genoa, before joining the automaker Innocenti in 1949.
Alfieri worked on the six- and eight-cylinder engines used in the Maserati A6 (1955), Maserati 250F (1957), as well as V8 racing engines, later to be used as a basis for the V6 of Maserati Merak and Citroën SM (1969).
Alfieri also developed the prototype 260 hp (190 kW) 4.0 L V8 engine for the SM, tested over 12,000 kilometers, proving that the capabilities of the chassis could easily accommodate a 50% increase in power. The engine was then removed and preserved, while the rest of the car was destroyed by Alejandro de Tomaso. The SM Club of France created an exact replica of this car using the actual engine from the original and displayed it at the 2010 Rétromobile show in Paris.
As Maserati was taken over in 1975 by Alejandro de Tomaso, Alfieri ended over 20 years of service for the Modenese company. De Tomaso had tried to buy Maserati in 1968 from the Orsi family. This failed primarily on Giulio Alfieri's resistance. After de Tomaso bought Maserati in August 1975, he dismissed Alfieri on the day of taking over the business. He was succeeded by Aurelio Bertocchi, the son of longtime Maserati test driver Guerrino Bertocchi.
He died in Modena in 2002.
