Method and data

Each model appears once, with the lowest combined fuel consumption of any petrol, diesel or hybrid version. Plug-in hybrids and electric cars are left out because their figures are not comparable. Official figures come from different test cycles (NEDC, WLTP, EPA) depending on the year and market, so treat small gaps with caution. How we collect and check data

Ranked: 15 of 1,149 models in the 1CARS catalog have a figure for this list.

How is this ranking compiled?

Each model appears once, with the lowest combined fuel consumption of any petrol, diesel or hybrid version. Plug-in hybrids and electric cars are left out because their figures are not comparable. Official figures come from different test cycles (NEDC, WLTP, EPA) depending on the year and market, so treat small gaps with caution.

Why is a model missing from the list?

A model is listed only when the 1CARS catalog has a confirmed figure for it. Models without an official figure stay out instead of getting an estimate, and the list grows as we add data. Concept cars, prototypes, one-offs and racing cars are not ranked; limited-run models are marked.
