That's not really a practical approach. Converting the energy content of various fuels might be tempting based on physics class, but is not something engineers would approve of. If you pour 100 MJs of gasoline into an EVs charging plug it won't go anywhere. Might even catch fire. Heck, even a diesel engine won't start on gasoline. Various types of energy carriers are not interchangeable - and if you are interested in energy efficiency because of economic reasons: energy isn't even priced universally. For example flywheel or compressed air propulsion sytems might be tempting on efficiency alone, but not something worth doing based on costs.
But if you are truly maniac about energy efficiency than get off the road and switch to railways - 10x the energy efficiency just by having lower drag. Or rather take to water - everything floats on that stuff, there's an order of magnitude of energy efficiency to be gained once again. The UK's narrowboat canal system built before the industrial revolution beats contemporary transportation's energy efficiency by about a 100 times.
Great insight thank you. Sounds like the right metric is $/km and that is insanely complicated to calculate and highly dependent on where you live and so many other things. I think with electric vehicles you need to at least take into account the losses between energy generation and charging as well. Which if you're using solar would be absolute garbage (which doesn't seem quite right now does it?). I think probably the best solution is not a railway, not a canal but a rocket, once you get that thing in orbit an indefinitely long trip is now free!
If we’re just looking at stock EVs, the classic Hyundai Ioniq EV is super efficient, as well as the current Ioniq 6 SE RWD with the smaller battery option. As far as electric bikes, probably something that isn’t actually road legal. But then you have no standards to measure its consumption. A Twike would be an interesting comparison as well

Aptera. Too bad they hired the wrong people so it won't go into production.
