Increased [[MTOW|gross weight]] and a [[tailplane]] fuel tank would have boosted its range by {{convert|11100|to|12025|km|nmi|-1|order=flip}}, and GE could offer its {{cvt|65000-68000|lbf|kN}} [[CF6]]-80C2/G2.<ref name=Flight20march2000>{{cite web |url=http://www.flightglobal.com/pdfarchive/view/2000/2000%20-%200694.html |title=Lauda and Kenya eye heavy 767 |last=Norris |first=Guy |work=Flight International |date=March 20, 2000}}</ref> Rolls-Royce offered its {{cvt|68,000-72,000|lbf|kN}} [[Rolls-Royce Trent#Second Trent 600|Trent 600]] for the 767-400ERX and the [[Boeing 747#747X and 747X Stretch|Boeing 747X]].<ref name=Flight25July2000>{{cite web |url=http://www.flightglobal.com/pdfarchive/view/2000/2000-1%20-%200364.html |title=R-R offers Trent 600 for 767-400ERX and 747X |work=Flight International |author=Julian Moxon, Guy Norris |date=July 25, 2000}}</ref>

Offered in July, the longer-range -400ERX would have a strengthened wing, fuselage and landing gear for a 15,000&nbsp;lb (6.8&nbsp;t) higher [[Maximum takeoff weight|MTOW]], up to 465,000&nbsp;lb (210.92 t).<!--ref name=Boeing26july2000-->
Thrust would rise to {{cvt|72,000|lbf|kN}} for better takeoff performance, with the Trent 600 or the General Electric/Pratt & Whitney [[Engine Alliance]] GP7172, also offered on the 747X.<!--ref name=Boeing26july2000-->
Range would increase by {{Cvt|525|nmi|mi km|abbr=on}} to {{Cvt|6,150|nmi|mi km|abbr=on}}, with an additional fuel tank of {{Cvt|2145|USgal|L|abbr=on}} in the horizontal tail.<!--ref name=Boeing26july2000-->
The 767-400ERX would offer the capacity of the [[Airbus A330-200]] with 3% lower fuel burn and costs.<ref name=Boeing26july2000>{{cite press release |url= https://boeing.mediaroom.com/2000-07-26-The-Newest-Boeing-767-Is-Inspired-By-The-Future-Introducing-The-Boeing-767-400ER |title= The Newest Boeing 767 Is Inspired By The Future - Introducing The Boeing 767-400ER |date= July 26, 2000 |publisher= Boeing}}</ref>
