Presented are segmented hairpin bar conductors for electric machines, methods for making/using such segmented bar conductors, electromagnetic motors using such segmented bar conductors, and vehicles equipped with an induction motor generator unit using segmented hairpin bar conductors. An electric machine includes a stator that defines multiple circumferentially spaced, radially elongated stator slots. A rotor is located adjacent and movable with respect to the stator. One or more permanent magnets are mounted to the rotor, and one or more U-shaped hairpin windings are mounted to the stator in juxtaposed spaced relation to the magnet(s). Each hairpin winding is formed from an array of collimated, electrically conductive wires that are bundled together into a unitary bar conductor. The segmented hairpin winding has a pair of hairpin legs, each of which adjoins and projects from a respective end of a hairpin crown. Each hairpin leg inserts into a respective one the stator slots.
