What the numbers actually say
There is 2.3 l/100 km between these two (6.2%). That is inside the 10% tolerance of declared figures, so on fuel alone neither is the better choice: at 120,000 km a year and an assumed £1.40 a litre the gap would be about 2,760 litres a year (£3,864). The declared figures for one of them alone span 7.5 l/100 km across its configurations, so the specification ordered matters more than the choice between these two.
