The weight of a full gas tank that can drive you 1000km is a lot less than the weight of batteries that can do the same. even if you include the ICE engine. In other words: even when you take conversion into account, energy density (both by weight and volume) is better in gasoline than battery. (I love BEV, and I see it will win over most of the market, but gas wins on energy density)
