sporty model: performance is goal, economy isn't.
From a factory POV, more model differentiation raises the UMC (Unit Manufacturing Cost), so that's "bad". But on the whole I agree with what you are saying.

In a way Honda is doing something like this with their eco/normal/sport button on the Honda CRZ. I think having a button like that is a no-brainer on almost all models. It won't change the options in the way you describe, but having a low-cost button + differentiating the software should keep the UMC under control.

Have the ECU/PCM help you get good MPG, not fight you.
