I have the following question, intended for a car powered by a 4 cylinder, non turbo, gas engine.
I would like to a rather conceptual answer, but anyway I will put some actual numbers.
It´s said to achieve it´s max torque (200Nm) at 4000 RPM
It´s max power is 150HP at 6500RPM
I don´t know the fuel consumption curve, but i know that the best km/litre is about 115KM/h (3000RPM)
At 4000RPM (max torque) the car runs at 130KM/h
At 6500RPM (max power) you get 200Km/h
Now, in a heavy load condition (five passengers, front wind and pulling a small trailer)... is it right to think that the best fuel efficency would be found at the max torque´s RPMs, let's say 4000RPM~130KM7h ?
thank you very much.
