The IMAM Ro.58 was an Italian twin-engined two-seat monoplane fighter a development of the IMAM Ro.57. First flown in May 1942 it was considered a general improvement over its predecessor mainly due to the substitution of higher power Daimler-Benz DB 601 engines for the Fiat A.74 engines used on the Ro.57. Initially it had many problems and during the maiden flight only the proficiency of the test pilot Adriano Mantelli saved the plane.
