tackles the tough question of domestic content in its latest American Made Index, and comes away with a surprising result: Toyota's Camry is the most American car on the market. Of course, making these distinctions in a global industry is fraught with difficulty. Though percentage of domestic parts content is tracked by the NHTSA for American Automobile Labeling Act compliance (PDF), those numbers count US and Canadian parts as being domestic. So has created its own list which requires US assembly, at least 75 percent US-sourced parts content, and factors in sales numbers because they correlate to the number of U.S. autoworkers employed to build any given model and to build the parts that go into those same cars. Taking out vehicles that are being canceled with no clear replacement, the following vehicles make up their top ten most American automobiles.

1. Toyota Camry (Georgetown, KY; Lafayette, IN)

2. Ford F-150 (Dearborn, MI; Claycomo, MO)

3. Chevrolet Malibu (Kansas City, KS)

4. Honda Odyssey (Lincoln, AL)

5. Chevrolet Silverado 1500 (Fort Wayne, IN)

6. Toyota Sienna (Princeton, IN)

7. Toyota Tundra (San Antonio, TX)

8. GMC Sierra 1500 (Fort Wayne, IN)

9. Ford Taurus (Chicago, IL)

10. Toyota Venza (Georgetown, KY)

In short, only half of the top ten most American vehicles are actually made by your taxpayer-owned automakers. Of course, a lot of that has to do with Detroit's tanking sales numbers, as well as GM's slashing of its Pontiac line (disqualifying its vehicles on the no obvious replacement front. Still, former AMI perennials like the Chevy Cobalt have fallen off the list because their percentage of domestic parts content has actually fallen. While none of this is conclusive in terms of measuring impacts on the American economy, it's another interesting look at an industry that is far too complicated to measure in terms of pure nationality.
