the passenger version of the Boeing 747-8, also known as the 747-8I for 'Intercontinental,' has a fuel capacity of 63,034 gallons (238,610 liters). According to Boeing, these aircraft have a range (based on a load of 410 passengers) of 8,900 miles (14,320 km). Dividing the latter by the former, we get a figure of just 0.142 miles per gallon.
The figure for the Boeing Business Jets (BBJ) version of the 747-8 is slightly more favorable. Indeed, based on an assumed capacity of just 100 VIP passengers, this private jet has a range of 10,213 miles (16,437 km), resulting in a figure of 0.162 miles per gallon. As for the 747-8F, which carries cargo, its range of 4,908 miles (7,899 km) and fuel capacity of 59,734 gallons (226,095 liters) give it a figure of 0.082 miles per gallon. But are these low figures as bad as they seem at face value? //
the 747-100, Boeing's data shows that this version of the iconic quadjet could typically fly for up to 5,320 miles (8,560 km). When this range is offset against the 747-100's maximum fuel capacity of 48,445 gallons (183,380 liters), we get a figure of 0.11 miles per gallon. As such, the 747-8's score on this front has improved by more than 29% from the oldest to the newest model. //
when we multiply the 747-8's figure of 0.142 miles per gallon by its capacity, for this purpose, of 410 guests, we get a much healthier figure of 58.22 passenger miles per gallon. Of course, a full five-seater car would only need to achieve around 11.65 miles per gallon to get a higher passenger miles per gallon figure, but, in reality, cars often only transport their driver. As such, in this regard, a fully loaded 747 can be more efficient than certain cars in the event of solo occupancy. //
