The 747-8 Freighter is longer than the 747-400F by 5.6 m (18.3 ft) and has a maximum structural payload capability of 140 metric tonnes (154 tons) with a range of 8,130 km (4,390 nmi). The additional 120 cu m (4,245 cu ft) of volume means the airplane can accommodate four additional main-deck pallets and three additional lower-hold pallets. Also powered by 787-technology engines, it will achieve the same environmental benefits as the 747-8 Intercontinental.
