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.

What each spec type actually measures

Fuel economy figures are EPA laboratory results: a combined rating weights the city cycle at 55% and the highway cycle at 45%, which is why the combined number is rarely the simple average of the two. Annual fuel cost assumes 15,000 miles a year at national average pump prices, so treat it as a way to rank vehicles against each other rather than a household budget. Electric and plug-in hybrid entries are additionally rated in MPGe, where 33.7 kWh is treated as the energy equivalent of one gallon of gasoline.

Dimensions and towing figures come from manufacturer submissions recorded in the NHTSA vPIC catalogue, reported per configuration — a crew cab with a short bed and a regular cab with a long bed are different rows because their wheelbase, length and rated capacity genuinely differ. Safety data combines NCAP crash-test star ratings, rollover resistance percentages, recall and complaint counts, and the availability of driver-assistance systems such as forward collision warning, lane departure warning and dynamic brake support. Maintenance intervals are manufacturer-published service schedules, normalised so brands can be compared on the same mileage basis.

How to research a vehicle here

Start from the make directory above or the search page if you know the model. Each model hub links to its own MPG, engine, dimensions, towing, safety and maintenance pages, along with the rival models most often cross-shopped against it. If you are weighing two vehicles, the comparison pages put their figures side by side; if you are shopping by number rather than by badge, the ranking and chart pages sort the entire database by a single metric. For a car you already own or are inspecting, the VIN decoder returns the exact build details recorded with NHTSA, and the maintenance schedule tool turns a model's service intervals into a mileage plan you can export.

Data is refreshed as the EPA and NHTSA publish new model-year records, and every page states the source and the date its figures were last verified. Where a manufacturer has not reported a value, the field is left blank rather than estimated — an empty cell here means the government dataset has no figure, not that the vehicle lacks the feature.

Reading a spec sheet without being misled

Most spec-sheet disputes come down to configuration. A maximum tow rating belongs to one exact build — a specific cab, bed length, axle ratio and drivetrain — and is quoted with a 150-pound driver aboard and nothing else in the vehicle. Add passengers, a tonneau, a toolbox and tongue weight at 10–15% of the trailer, and payload usually runs out thousands of pounds before the tow rating does. The number that governs your trailer is the payload figure on the door-jamb sticker of the truck in your driveway, not the headline in the brochure.

Dimensions carry the same trap. Published width excludes mirrors, which add roughly 8 to 12 inches, so a 79-inch SUV needs about 89 inches of real clearance. Overall height is measured at curb weight without roof rails or a cargo box, and parking structures typically allow 80 inches. Wheelbase, not length, predicts how much of a vehicle is usable cabin: above 112 inches means adults fit in the second row, above 120 inches means a genuinely usable third row, and two vehicles of identical length can differ by eight inches of rear legroom depending on overhangs.

Fuel economy figures are comparative instruments. The highway cycle averages 48 mph, well below interstate speed, and drag rises with the square of velocity, so sustained 80 mph driving costs 15–20% against the sticker. Cold starts, winter fuel blends, roof loads and short trips widen the gap further. When you are converting a difference into money, work in gallons per 100 miles rather than MPG: moving from 20 to 25 MPG saves more fuel over a year than moving from 35 to 40.

Safety ratings are not interchangeable between model years. NHTSA revises its test protocol periodically, so a five-star result from an older program is not directly comparable with a five-star result under the current one, and an unrated configuration is simply untested rather than unsafe. Recall and complaint counts on a model page are raw volumes: a high-selling nameplate accumulates more of both without necessarily being less reliable, so read them against production volume and severity rather than as a score.
