A hybrid-electric four wheel drive vehicle (HEV) 10 and a powertrain for a fourwheel drive HEV having an electrically driven axle 14 and a mechanically driven axle 16. The powertrain may comprise: an internal combustion engine (ICE) 20; an electromagnetic machine 24 capable of transferring mechanical power and generating electrical energy; and an electric machine 32. The electric machine 32 drives the electrically driven axle 14 and wherein the ICE 20 drives the mechanically driven axle 16. The electromagnetic machine 24 is controllable such that a torque requirement can selectively be met by mechanical power generated by the ICE 20 distributed directly to the mechanically driven axle 16 and by electrical energy provided to the electric machine 32 to drive the electrically driven axle 14.
