This power allows the 747-8F to carry up to 300,000 pounds of cargo over distances exceeding 7,000 nautical miles, making it a cornerstone of the global air logistics network. Fuel Efficiency and the Modern Quad-Engine One might assume that four engines would be a significant liability in terms of fuel consumption; however, the 747-8 engines are a triumph of modern technology.

In the ultra-long-range passenger variant, the 747-8 can continue safely on a single engine for an extended period, opening up vast routing options over remote areas like the North Atlantic and polar routes. Developed by General Electric as the GE90-115B derivatives for the passenger variant and the GEnx-2B67 for the freighter, these powerplants are engineering marvels designed to deliver exceptional performance, reliability, and efficiency for the demanding long-haul and high-capacity cargo sectors.
The 747-8 engines represent the pinnacle of modern heavy-lift aviation, forming the very heart of the Boeing 747-8 Intercontinental (748) and the 747-8 Freighter (748F). To manage the complex airflow interactions between the engine and the wing, particularly at low speeds and high angles of attack, the aircraft features vortex generators and an intricate wing leading-edge design.

Mounted on the upper surface of each wing in an underslung pylon, these engines are rated to produce a massive thrust of approximately 134,000 pounds-force (600 kilonewtons) each. This, combined with advanced aerodynamics and lightweight composite materials, ensures that the 747-8's fuel burn per passenger-mile is competitive with modern twin-engine wide-bodies on comparable routes.
