An engine with a hybrid crankcase includes the crankcase being a composite construction having an exoskeleton formed of a non-ferrite material having no defined endurance limit as a material, the non-ferrite exoskeleton encapsulating a load bearing skeleton formed of a ferrite material, the ferrite material having a well defined endurance limit, whereby the skeleton acts to carry the highest engine loadings. A method of forming such an engine is further included.
