The Isotta Fraschini Asso 750 was an Italian W 18 water-cooled aircraft engine of the 1930s.

Produced by Isotta Fraschini the engine displaced just under 48 L (2,900 cu in) and produced up to 940 hp (700 kW).

The W-18 Asso 750 had three six-cylinder in-line banks made of chrome-manganese steel, each joined by a single cast aluminum head for each bank of cylinders.

A version with an effective power of 940 hp (700 kW) was optimized for the Savoia-Marchetti S.55X used for the trans-Atlantic flight of Italo Balbo.
