How this list is built
Every line below is read from the list definition that produced the table.
- Classes: every EPA class except special-purpose vehicles.
- Powertrains: Gas, Hybrid, Diesel.
- Ranked by EPA combined MPG, lowest first.
- One row per model (make and model): the configuration that ranks best in this list is shown, with its trim, engine and drive named in the row.
- Ties are decided on the displayed value (whole MPG or miles, kWh per 100 miles to one decimal, cost rounded to $10): tied models share a rank, then are ordered by a tie-breaker and by name.
- Special-purpose vehicles, such as heavy-duty variants, are excluded.
- Electric vehicles are ranked separately (see the EV rankings): gas, hybrid and diesel MPG is never mixed with MPGe.
- Annual cost assumes 15,000 miles a year at the EPA rating and the dated national fuel prices stamped below; it is rounded to $10 and all differences use the rounded values.
- Model years MY2000 to MY2027; a year is listed only when at least 10 models qualify.
