Most used tool
Free VIN decoder — specs & towing capacity by VIN
Paste any 17-character VIN to get the exact build: engine, displacement, transmission, drivetrain, GVWR class, body class and plant — then jump straight to that vehicle's towing capacity, payload and MPG. Powered by NHTSA vPIC, no account needed.
Visual tool
Car size comparison
Overlay any two vehicles to scale and see real length, width, height and wheelbase differences before you commit to a garage or parking space.
Rankings
Best gas mileage, ranked
The most efficient SUVs, trucks, hybrids and EVs, ordered by EPA-tested combined MPG, lowest annual fuel cost and lowest emissions.

Every spec type, on one page per vehicle
Most sites split specs across separate domains. We keep MPG, engine, dimensions, safety and cost data together for each model.
Fuel economy (MPG)
City, highway and combined MPG for every model year, engine and trim, plus EV range and MPGe.
Engine & drivetrain
Cylinders, displacement, forced induction, transmission type, gear count and drive layout.
Dimensions & capacity
Length, width, height, wheelbase, cargo volume and fuel tank capacity for size and fit decisions.
Towing & payload
Towing capacity, payload and GVWR where published, with calculators for trailer weight.
Safety ratings
NHTSA NCAP overall, frontal, side and rollover star ratings by model year.
Running costs
Estimated annual fuel spend, CO₂ emissions and five-year gas-vs-EV cost of ownership.

FAQ
Common questions
Where does AutoSpecData get its vehicle specifications?
Every spec comes from official U.S. government datasets: fuel economy, engine and emissions data from the EPA's fueleconomy.gov database, and VIN decoding, dimensions and crash-test ratings from NHTSA vPIC and NCAP. Nothing is user-submitted or estimated.
How do I find the towing capacity for my vehicle?
Enter your VIN in the free VIN decoder, or search your make and model and open its specifications page. Towing capacity, payload and GVWR are listed by model year and trim where the manufacturer publishes them.
Is AutoSpecData free to use?
Yes. Every specification page, comparison, ranking and calculator is free with no sign-up. The site is supported by advertising and affiliate links.
How many vehicles are in the database?
More than 15,800 vehicle configurations across 62 makes and 619 models, covering model years 2015 through 2027, with new model years added as the EPA publishes them.
How often is the data updated?
Vehicle data is re-ingested from the EPA and NHTSA feeds on a recurring schedule, so new model years and newly published crash-test ratings appear automatically.
About AutoSpecData
AutoSpecData is a free vehicle specification database covering more than 15,800 car, truck and SUV configurations from 2015 to 2027. It aggregates fuel economy, engine and emissions data from the U.S. Department of Energy's fueleconomy.gov database with VIN decoding, dimensions and crash-test results from NHTSA. Unlike fragmented sites that split specs across multiple domains, we bring every data type — MPG, engine specs, dimensions, towing capacity, safety ratings and running costs — together in one place for each vehicle.
Every spec is sourced from official government data, not user submissions or estimates. When you see the verified badge, the figure comes directly from EPA testing or NHTSA records — the same sources dealerships and manufacturers reference. Pages are free to use, need no sign-up, and are supported by advertising and affiliate links.
