What the numbers actually say

There is 2.8 l/100 km between these two (7.8%). 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 3,360 litres a year (£4,704). The declared figures for one of them alone span 8.3 l/100 km across its configurations, so the specification ordered matters more than the choice between these two.
