How these figures are produced

Specifications and counts come from the VehicleScore UK vehicle catalogue. A count of cars is the number of records in that dataset. It is not UK production, not sales, and not the number of cars currently on the road.

Power is shown in PS where the catalogue stores PS, and in bhp only where bhp is stored separately. Official fuel economy is labelled NEDC or WLTP when the test cycle is known. Figures from different cycles are not ranked together. Empty values are left blank.

The catalogue does not store a revision date, so these pages do not show a last-updated day.
