Answers use the same data and method as above.
How we rank (n ≥ 20, shrinkage, 5% trim)
- Real-world figures only with ≥ 20 cars, each with ≥ 3 months of data
- Scores pulled towards the segment average so thin samples can't jump to the top
- Top & bottom 5% dropped, anomalies filtered
- No payment to add, hide or reorder anything

Which segment C cars are the most fuel-efficient in 2026?
No model has enough data on this board yet (updated Oct 12, 2026).
Why are some models missing?
This board uses community data only: models with fewer than 20 cars sharing data are not ranked and get no projection.
Where do the real-world figures come from?
From the fill-ups and charging sessions owners log in the CarCost app (median per car, then median per model). This board uses community data only: models without enough data are not ranked.
Can car brands pay to rank higher?
No. CarCost does not sell positions and every board uses the same public method. A row under review may be hidden temporarily, which never changes the other cars' ranks.
