Scania P 500 B8x4*4 vs Scania R 500 B8x4*4
What the numbers actually say
There is 0.8 l/100 km between these two (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 960 litres a year (£1,344). The declared figures for one of them alone span 10.6 l/100 km across its configurations, so the specification ordered matters more than the choice between these two.
