What the numbers actually say

There is 0 l/100 km between these two (0%). That is inside the 10% tolerance of declared figures, so on fuel alone neither is the better choice. The declared figures for one of them alone span 7.8 l/100 km across its configurations, so the specification ordered matters more than the choice between these two.
