Car database

Fuel economy, running costs, emissions and safety — from official U.S. data

Browse 270 popular models by make, then by year, for EPA fuel economy, annual fuel cost, CO₂ emissions, electric range and NHTSA safety ratings. Every figure is drawn from the U.S. EPA and NHTSA, and any two vehicles can be lined up in the side-by-side comparison tool.

How to use the database

Start with a make, then a model, then the model year. Each vehicle page shows every configuration the EPA tested for that year, so you can see how the engine and drivetrain change the fuel bill, and the model overview shows how a car's economy moved from one year to the next. The comparison tool puts any two or three vehicles side by side.

Where the numbers come from

Fuel economy, annual fuel cost, electric range and CO₂ emissions are the official estimates from the U.S. EPA's FuelEconomy.gov files; crash ratings come from NHTSA's New Car Assessment Program. Both are public-domain U.S. government datasets. Real-world fuel economy varies with driving style, weather and load, so read the figures as comparisons between cars rather than a promise of your own mileage.

What we cover

The database focuses on the models people actually buy and run — the best-selling cars, trucks, SUVs and minivans, alongside the most popular electric and hybrid models, where the running-cost differences between cars are largest.
