#2. It's much more fuel-efficient to accelerate on level ground than to accelerate on an uphill grade. Accelerating up hills, my mpg is typically in the teens, below 20 mpg. Accelerating on flat land, I can double that, but I don't. For best BSFC, I still accelerate getting below 20 mpg. The difference is, I only need to accelerate for mere seconds on flats. When I accelerate going uphill, I may have to do it for minutes at a time.
