Presented are electric machines with both bar and wire conductors, methods for making/using such machines, and vehicles equipped with such machines. An electric machine, such as a traction motor or electric generator, includes an outer housing, a stator fixedly mounted to the housing, and a rotor movably mounted to the housing and spaced across an airgap from the stator. Multiple magnets, such as permanent magnet blocks, are mounted on or in slots of the rotor (or the stator). A set of electromagnetic conductors extends through each radially elongated slot of the stator (or the rotor). Each conductor set includes a group of solid-wire or multistrand-wire conductors that is located adjacent the airgap. A group of hairpin or I-pin bar conductors is radially spaced from the airgap and located adjacent the wire conductors. The bar conductors have a cross-sectional area/shape that is distinct from a cross-sectional area/shape of the wire conductors.
