Simple Flying released an analysis on May 16 examining the fuel efficiency of the Boeing 747-8, comparing it to earlier models and other modes of transportation. The article discusses how the Boeing 747-8, known for its large size and four engines, achieves a fuel consumption rate that is lower than previous generations but still significantly less efficient than most modern cars when measured in miles per gallon.
The topic is relevant as airlines and travelers consider both economic and environmental impacts of widebody aircraft. The report notes that while the passenger version of the Boeing 747-8 can travel approximately 0.142 miles per gallon, this figure improves to about 58.22 passenger miles per gallon when accounting for its seating capacity of up to 410 passengers.
Earlier versions such as the original Boeing 747-100 had even worse rates, at around 0.11 miles per gallon, but each subsequent model has shown incremental improvements in efficiency. “As we shall discuss in greater detail later in this article, calculating an aircraft’s (or, indeed, any given vehicle’s) fuel efficiency in terms of the number of miles that it travels per gallon of fuel consumed is a complicated matter,” said Simple Flying.
The analysis also addresses factors influencing aircraft fuel consumption beyond raw numbers: payload weight, altitude flown, weather conditions such as tailwinds or headwinds—all play a role in determining real-world performance on any given flight. According to research cited by Simple Flying from Poznan University of Technology published by the Polish Scientific Society of Combustion Engines, tailwinds can reduce fuel use by up to fourteen percent compared with similar-strength headwinds.

Despite reduced demand after events like the coronavirus pandemic led some airlines to retire their fleets early—such as British Airways—the Boeing 747-8 remains active globally with more than eight thousand scheduled flights reported for this year.
