I would have loved to say accelerate at max BSFC, but then that would stump the audience this is aimed at, who may happen on this article. I feel 2000-3000 rpm acceleration is a good average range for most engines which conveys to the masses that getting good (not optimum) mpg is not all about accelerating like "grandma". I personally found in my 2010 Prius that accelerating reasonably fast (in the HSI mid PWR region) has little impact on my overall mileage, but non-optimum braking has a big impact (the low hanging fruit if you will). It's nice that I can have the fun of quick acceleration and have a 60 mpg average (displayed) 58 mpg (calculated), which I know would be better if drove below 60 mph on the highway. I tend to cruise around 63 mph (displayed) on the highway plus or minus 5 mph to keep within 3% of the peak BSFC.
