I think of the metabolic efficiency rate as equivalent to the engine efficiency, and the overall body mechanical efficiency equivalent to fuel economy (ie power output at the crankshaft v power output at the wheel)
When you consider idling, accessory, drivetrain, and braking losses the ICE dips well below its theoretical efficiency too.
Look, someone already made the chart:
No idea what their sources are or if its reliable
