An electric machine includes a stator core defining slots and a hairpin winding path disposed in the slots. The winding path includes first and second hairpins having legs with same slot spans and twist with same slot spans. The hairpins are installed in the core such that one of the twists of the first hairpin crisscrosses with one of the twists of the second hairpin. A reverse jumper joins the twists that crisscross.
