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.
