A hybrid vehicle comprises an engine output shaft 55 which is coupled to a motor/generator shaft 45 by a one-way clutch 70 which allows the motor/generator 40 to rotate faster than the output shaft 55, whilst not allowing it to rotate faster than the motor/generator shaft 45. The clutch 70 is arranged to never transmit torque from the motor/generator 40 to the engine 50, and to transmit torque to the motor/generator 40 when the clutch 70 locks the engine output shaft 55 and the motor/generator shaft 45 to rotate to the same speed. The hybrid vehicle comprises one or more auxiliary loads 60, connected directly to the motor/generator output shaft 45 so that the loads 60 are driven whenever the motor/generator shaft 45 rotates. The auxiliary loads 60 are driven by motor/generator 40 alone when the motor/generator 40 functions as a motor and rotates the motor/generator shaft 45 faster than the engine output shaft 55. The invention allows auxiliary loads 60 to be driven by the engine 50 when torque is transmitted via the one way clutch 70 from the engine output shaft 55 to the motor/generator 40.
