How CarCody ranks

Car lists use the official US EPA figures from fueleconomy.gov: combined MPG for fuel and hybrid cars, rated range and MPGe for electric cars, one row per model year and drivetrain. Software is ranked on what each maker publishes. Paid placements never change a rank.

What goes into a score

Every ranked list on CarCody uses the same published signals, read from each maker's own pages. A score runs from 4.0 to 9.8:

• 42% — how established the product is in its category (makers that buyers already compare)
• 28% — how completely the maker documents its product, plans and terms
• 14% — how many platforms it runs on
• 10% — whether there is a free trial
• 6% — whether there is a free plan

Lists that are directories rather than rankings — sorted by year, by code or by a single published figure — say so in their title and are never called "best".

What never changes a rank

• Payment. Sponsored rows are labelled and sit beside the ranking, not inside it.
• A claim. Makers can correct facts; they cannot set their score.
• Affiliate links. Whether a link earns anything has no part in the order.

Freshness

Each list shows the date its facts were last checked. Facts are re-read from the source when a maker changes a page or sends a correction.
