What “option” means here
An option is an EPA vehicle record, often separated by engine, transmission, drive or fuel type. It may not match a marketed trim name.
FuelEconomy.gov national dataset
Select a model year, make and model to see every certified engine, transmission, drivetrain and fuel configuration attached to that nameplate, drawn from FuelEconomy.gov's public dataset going back to 1984. An "option" here means an EPA vehicle record, not a marketed trim name. A single trim offered with two engines produces two configurations, and two trims sharing an engine and drivetrain can share one EPA configuration instead. Records can look alike at a glance while differing in transmission, a mid-year running change or emissions certification, so open each one before treating similar-looking rows as duplicates. Fuel economy is certified per configuration, not per model, so transferring a favorable rating from one drivetrain or powertrain to the one you are actually buying is a common and avoidable mistake. 5 common questions about how this dataset is structured are answered below.
Checking the public record…
An option is an EPA vehicle record, often separated by engine, transmission, drive or fuel type. It may not match a marketed trim name.
Two configurations can share a visible label while carrying different certification details, emissions information or vehicle IDs.
Fuel economy belongs to the selected configuration. The best rating in a model family does not apply to every drivetrain or powertrain.
One EPA certification record: a specific engine, transmission, drivetrain and fuel-type combination for a given model year. A single marketed model frequently certifies as several configurations: for example a gas and a hybrid version, or front- and all-wheel-drive versions, each with its own separately measured fuel economy.
Not necessarily. EPA groups vehicles by powertrain and drivetrain, which is a different axis than a manufacturer's marketed trim ladder. Two trims that share an engine and drivetrain can share one EPA configuration; a single trim offered with two engines produces two configurations.
Different certification details, a different transmission, a mid-year running change, or a separate emissions certification, can produce two configuration records that look alike at a glance. Open each one to see exactly what differs before treating them as duplicates.
No. Fuel economy is certified per configuration, not per model. Transferring a favorable rating from one drivetrain or powertrain to a different one you are actually buying is a common and avoidable mistake.
To 1984, FuelEconomy.gov's earliest certified model year, through the current model year as EPA publishes it.
