A motor vehicle 5 is disclosed having an engine 10 driving a multi-speed gearbox 15 via a friction clutch 12. The engine 10 is arranged to drive a number of electrically controllable loads 20 the level of load applied by each of which to the engine 10 is controlled by an electronic controller 50 in response to a number of inputs 30. When the inputs 30 indicate that an upshift of the gearbox 15 is to take place the electronic controller 50 is arranged to increase the loads applied by the electrically controllable loads 20 to the engine 10 and when the inputs 30 indicate that a downshift of the gearbox 15 is to take place the electronic controller 50 is arranged to decrease the loads applied by the electrically controllable loads 20 to the engine 10 thereby improving the quality of the gear change irrespective of whether it is an upshift or a downshift.
