EV Data Assessments

How the score is built

Each metric is ranked against every other EV in the same body class and mapped to a 20-100 band, where the tied midpoint is 60, not 50. Metrics roll up into three pillars, weighted 25% reliability, 25% efficiency, and 50% economics — because running cost is what this site exists to measure. Cohorts under five receive neutral percentile scores, never cross-class comparisons. Recorded recalls are neutral because coverage and fleet exposure are unverified. Where a model has no model-specific degradation curve or curated issue list, that metric is scored neutrally and labelled as such on the vehicle page rather than silently assumed clean.
