A control system and a method controlling an engine and an electric traction motor of a hybrid electric vehicle are provided. The control system comprises one or more controllers. The control system is configured to: receive a signal indicative of a requirement to increase engine speed 600; control the electric traction motor and/or the engine to provide positive torque 612, 614 to increase engine speed, in dependence on receiving the signal; control the engine to provide a change in torque towards an engine torque target, different from a torque required to maintain engine speed at an engine speed target associated with the requirement to increase engine speed; and control the electric traction motor to provide an inhibiting torque (t2 to t3, Figure 6B) to inhibit the change in torque of the engine from causing a deviation of engine speed from the engine speed target 600.
