Boeing 747 8 Specifications.

The Boeing 747 8 Freighter and 747 8 Intercontinental are the largest iterations of the classic Boeing 747 model which has the ruled the skies for four decades. It is the largest and heaviest aircraft produced in the United States.

The new 747 8 is the next generation of this iconic aircraft and benefits from technologies and enhancements that were used to create the Boeing 787 Dreamliner.  New wing technology, engine technology and also increased length to enable a larger passenger payload to be carried.

…. insertion of an extra 5.6 metres….

Below you can see where the extra length was inserted on the 747 8 Intercontinental passenger version as well as the 747 8 Freighter version. The insertion of an extra 5.6 metres (220 inches) of length as compared to the Boeing 747 400 is slightly different for the 747 8 Intercontinental as compared to  the 747 8 Freighter.  For the 747 8 Freighter this is done by inserting an extra 4.1 metres of fuselage length at the forward wing root.  The purpose for this is to do it behind the upstairs bubble and thereby not increase the bubble size but rather make it smaller, more reminiscent of the Boeing 747 100 and Boeing 747 200 series.    The 747 8 Freighter does not carry passengers therefore the bubble is redundant other than the house the cockpit.  The 747 8 Intercontinental on the other hand has the forward insertion of 4.1 metres (220 inches) placed forward of the wing root so that it takes in the upstairs bubble as well.  This way the upstairs bubble as well as the main deck are extended, increasing the seating capacity dramatically.  By how much exactly depends on the airline and what seat pitch they want to apply.  Both the 747 8 Freighter and the 747 8 Intercontinental have an insertion of 1.5 metres behind the wing root in the same place.
