Wikipedia: "The 777-300ER ("ER" for Extended Range) is the B-market version of the −300. It features raked and extended wingtips, a new main landing gear, reinforced nose gear, and extra fuel tanks. The −300ER also has a strengthened fuselage, wings, empennage, and engine attachments.The standard GE90-115B turbofan is the world's most powerful jet engine in service, with a maximum thrust of 115,300 lbf (513 kN). The maximum range is 7,930 nautical miles (14,690 km), made possible due to a higher MTOW along with the increased fuel capacity.[144][145] The −300ER can fly approximately 34 percent further than the −300 with a full load of passengers and cargo. Following flight testing, the implementation of engine, wing, and weight modifications produced an added 1.4 percent reduction in fuel consumption."
