I think you got your ordering wrong. From your source:
The overall energy intensity of the intercity bus mode, which is measured in BTUs (British thermal units) per passenger-mile, is 713, compared with 2,441 for intercity passenger rail (Amtrak); 3,999 for certified air carriers; and 4,238 for public transit buses. Automobiles experience 3,671 BTUs per passenger-mile.
