How it's calculated

Official type-approval data for the new passenger cars registered in the European Union, published by the European Environment Agency. One spot per model (its best version), and only versions with at least 30 registrations, to rule out errors in the records. Ratio = mass in running order (kg) divided by power (hp).

By powertrain, based on each version's official type approval: “Combustion” covers petrol, diesel, LPG, CNG and ethanol; “Hybrids”, both regular and plug-in hybrids; “Electric”, fully electric cars. With a powertrain selected, each model appears with its best version of that powertrain.

Each model's body type (SUV, hatchback, sedan…) and size come from its Wikidata classification and our own review of the best-sellers; models without a type yet only appear under “All”.

We automatically check for new data every 6 hours (last check: September 25, 2026 at 02:17 PM GMT+2). This is the type-approval data declared by manufacturers and it may contain errors.
