How it was built
Each year, automakers file a report with the National Highway Traffic Safety Administration for every passenger vehicle up to 8,500 lb sold in the US. It lists the final assembly country, the share of parts made in the US and Canada, and where the engine and transmission come from. We combined the 2025, 2026 and 2027 reports into one record per model and year. Heavier pickups and vans are not covered, and some models are filed later in the year.
