I've noticed some discussions regarding the use of WOT and whether it can be helpful or not to achieve maximum overall mpg. I have a number of instances where I'll be stopped at a red light before having to accelerate up a long, steep hill. Sometimes the hill will climb for up to a mile. I've noticed that even when I apply a steady pressure on the gas pedal that when the hill takes a stronger ascent that the engine rpms suddenly increase from 1900 to over 3000. It's as if the engine senses the sudden increase in grade and adjusts to compensate. I've been consciously trying to counteract this and keep the rpms down by releasing pressure from the gas pedal. However, there are times when I'm being pressured from behind and will allow the car to accelerate more rapidly up the hill instead of creeping along (in a manual, you guys would refer to it as "lugging"). If I'm at a higher speed and maintain at least 45mph the ifcd seems to be more stable at a higher number. What are your thoughts/experiences with this? Any thoughts Tarabell? Since the car seems to automatically "downshift", do you all think it is designed this way to be more efficient?
