Abstract: A composite conductor for a vehicle, a propulsion system for a vehicle, and a method of forming a composite busbar for a vehicle. The composite conductor includes a surface, and a first copper tape laminated to the surface. The composite conductor is electrically conductive exhibiting an electrical conductivity of 1.0×10{circumflex over (7)} Siemens per meter (S/m) or greater. The first copper tape includes a layer of carbon nanotubes sandwiched between a first copper layer and a second copper layer. The composite busbar may be connected to a plurality of windings in the stator of an electric motor.
