For the FC 250 emphasis in power delivery was placed on an increase in power and torque in the upper speed range. Due to the increase in output in the upper speed range a modified power and torque results in the lower speed range. This means a slightly later but as a result more spontaneous onset of full engine power from a speed of 6000 rev/min.
