Reply to comment by [deleted] in ELI5:Why aren't ultracapacitors used more often as range extenders in Hybrids? by EvolutionVII

Well I imagine the engine could constantly run at a sweetspot like 2000 rpm for increased fuel efficiency.

That doesn't require a super cap. You can just strap the e motor to the engine directly. Or use a battery as buffer.

So long as you don't NEED super fast charge/discharge, which this application doesn't, batteries are pretty much always better than caps.
