The present disclosure relates to a powertrain controller (3) for controlling a torque distribution between a front axle (4) and a rear axle (5) of a vehicle (1). The powertrain controller (3) includes a processor (8) and a memory device (9). The processor (8) is configured selectively to implement first and second torque distribution profiles (TDP1, TDP2) defining the torque distribution between the front axle (4) and the rear axle (5). The processor (8) determines when one or more vehicle dynamics parameter (VDPn) is within one or more predefined stability margin (VSMn) and when the one or more vehicle dynamics parameter (VDPn) is outside the one or more predefined stability margin (VSMn). A torque request signal (STQR) is monitored to identify a change in a torque request (TQR). The first torque distribution profile (TDP1) is implemented when the one or more vehicle dynamics parameter (VDPn) is within the one or more predefined stability margin (VSMn). The second torque distribution profile (TDP2) is implemented when the one or more vehicle dynamics parameter (VDPn) is outside the one or more predefined stability margin (VSMn) and the identified change in the torque request (TQR) comprises a decrease in the torque request (TQR). The present disclosure also relates to a vehicle including a powertrain controller (3); a method of controlling a torque distribution between the front and rear axles (4, 5) of a vehicle (1); and a non-transitory computer-readable medium.
