Hello . my father has a MK2 Focus With 1.6l Ti Vct with 115ps.
So i would like to know in which rpm's the car has better power to fuel ratio ? Are the rpm's in peak torque or no ? I am asking cause some say that the lower the rpms the better the fuel efficiency - economy. Also i saw a diagram with Rpms Fuel consumption torque and hp but it was for an BMW M20 engine i would like to see one for the Duratec also. but i cant find one.Thanks in advance
