Every declared fuel and CO₂ figure behind this site, as one CSV. It is the manufacturers' own declarations to the EU regulator, grouped by model and stated with the spread and the number of vehicles behind each figure. Nothing is modelled and nothing is projected.

What is in it
| Column | What it is |
|---|---|
| make, model | the make and the model page this figure belongs to |
| mission, payload_kg, fuel_type | the simulated route, its payload and the declared fuel — a figure is only ever comparable within these |
| reporting_period | the year the declaration belongs to |
| l_per_100km_median, _min, _max | the median declared figure and the lowest and highest behind it |
| co2_g_per_tkm_median, _min, _max | the same for CO₂ per tonne-kilometre |
| vehicles_behind, configurations_behind | how many declared vehicles and how many distinct configurations stand behind the figure |
| source, source_licence | the source that stated it, and that source's own licence |
Reporting periods 2019 to 2022; 679 models in the most recent year. What the numbers show is written up in fuel efficiency over time.
What it is not
It is not road-test data and not our measurement. A declared figure is a simulation of one standard route at one payload, made by the manufacturer under Regulation (EU) 2017/2400 and reported under Regulation (EU) 2018/956. It compares vehicles with each other; it is not what one truck uses on one road.How we know sets out the rest.
