Declared by the manufacturer to the EU regulator, simulated on a standard route and payload: these figures compare vehicles with each other, not what one lorry uses on one road. How fuel is compared.

Registered figures are counted over registrations; the register does not identify each vehicle's build, so they are not checked build by build. Drawn to the median registered figures. Lines are drawn only for recorded values. Where no source records a part — the cab, the front overhang — it is drawn to a stated convention and is not dimensioned.

Comparable means: both vehicles record a form and an axle configuration, and they are the same; both figures are the same kind of figure, from the same market; engine power is within 20% of the lower of the two and gross weight within 25%. A model declared on the same mission, payload, vehicle group and reporting period comes first, then the closest power; at most six.
