About AutoSpecData
AutoSpecData is a free vehicle-data reference. Every number on the site comes from a named public source and is shown with the year and trim it belongs to.
Why this site exists
Vehicle specifications are public information, but they are scattered across government databases, PDF owner's manuals, and forum posts. Most sites that aggregate them strip out the year, the trim, and the source, which is exactly the context that decides whether a number applies to your car. AutoSpecData keeps that context attached to every value.
What you'll find
- EPA fuel economy: city, highway, and combined MPG by year and trim
- Engine configuration: cylinders, displacement, and fuel type
- Transmission and drivetrain by model year
- EPA vehicle class and estimated annual fuel cost
- Maintenance intervals computed from each vehicle's powertrain
- Side-by-side model comparisons and fuel-economy rankings
How we work
Our methodology page explains where each data type comes from, how it is refreshed, and what its limits are. If a value is not verified, we do not publish a page for it.
Corrections
If you spot a value that does not match your vehicle's documentation, tell us on the contact page and include the year, trim, and the source you are comparing against.
