Dunno, a modern UK car will get 60mpg on motorway travel (that's what I've had), or even more. that's 50miles per us gallon. 2 passengers means 747 fully loaded efficiency, 3 wipes the floor. Of course a 747 in a domestic Japan configuration will have more passengers than a typical BA 747 tatl flight with 100+ beds.
