Good. Keep them at WOT and near/at peak torque while climbing. Coast down the other side of the hill.

The sizing of the engine has nothing to do with it. Regardless of which car you are in, drive like Ecky and I are saying. It is the most efficient way. Get the work done with the engine at peak torque and WOT. Coast down the other side. Avoid wind drag.

Obviously if you encounter wind resistence while climbing the hill, you are going to burn more fuel. But the hill itself did not take more energy from the vehicle. That was the wind. Not the hill.

There is no indication that you are discounting aerodynamic drag!

I see. You assumed extra conditions when I specifically addressed the factor of grade resistance. Grade resistance, rolling resistance, wind resistance, and vehicle parasitic losses are all separate factors.

We are talking about grade resistance and how to leverage it most efficiently.
