Sources and Methodology
How EV Guide defines fields, ranks EVs, validates source quality, and publishes static audit outputs.
Audit status Pass 0 warnings
Visible fields Complete 50 primary trims
Source metadata 4,079 Per-field rows
Canonical compares 1,225 One URL per pair
Source quality tiers
Canonical source rows live in data/source-metadata.csv; generated metadata also includes derived, image, sales, and editorial provenance.
Manufacturer official manufacturer103 rows in the current metadata file
Government official government796 rows in the current metadata file
Configurator dealer or configurator0 rows in the current metadata file
Reference trusted reference2,196 rows in the current metadata file
Derived derived984 rows in the current metadata file
Fallback rules
Official firstManufacturer specs, configurators, press kits, and fueleconomy.gov are preferred.
Reference fallbackEVKX field-level rows are labeled as trusted references and remain auditable by exact value, URL, capture date, and freshness date.
Derived fieldsValue, efficiency conversions, and road-trip scores are calculated from source-backed inputs.
Displayed fieldsConsumer-facing fields render only when source-backed values exist; core shopper fields hard fail.
Current audit warnings
Open JSONNo warningsThe current audit has no warning-level issues.
Deep spec enrichment backlog
Primary visible fields are strict. Populated deep specs require canonical field-level metadata; optional fields without values are omitted from consumer UI.
