The Isotta Fraschini Zeta was an air cooled X engine with 24 cylinders developed by the Italian engineering company Isotta Fraschini in the 1940s. It was developed as an indigenous alternative to the imported Daimler-Benz DB 605 that was being built under licence as the Fiat RA.1050 R.C.58 Tifone. The engine was essentially two Gamma V12 engines on a single crankshaft, but proved troublesome to develop and never entered production.
