This said my understanding is thermal efficiency in a typical engine is around 20%, and in an electric motor it’s in the 90% range. Holding traction aside I would have assumed the power is considerably more important than energy density, and energy density plays a bigger role in distance, no?
After 500 hours of Kerbal space program I’m a bit of an expert in these things.

For distance, it can be (usually is?) the energy/volume that is the limiting factor, but for acceleration, it is the energy/weight as weight is the other balancing factor, besides power, of your acceleration equation.
