DAF CF 450 FAN vs DAF XF 450 FAN
What the numbers actually say
There is 3.1 l/100 km between these two (9.7%). 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 3,720 litres a year (£5,208). The declared figures for one of them alone span 6.3 l/100 km across its configurations, so the specification ordered matters more than the choice between these two.
