That's funny because that technique seems to more or less work in the Insight. I don't "floor it", but I accelerate fairly quickly. Maybe I will do some comparisons, but my perception in the past was, a short burst of low MPG w/high assist and then maintaining speed worked better than a longer burst of higher (but still low due to acceleration) MPG and then the same. Maybe it has something to do with the Insight's lightness and the fact it only has a 3 cylinder engine. Maybe the electrical assist adds more assist in comparison to engine output.
