The index ranks and measures according to location of assembly, content of domestic-made parts, where the engine and transmission are made and each automaker’s direct U.S. factory employment relative to its sales footprint.

Of the Toledo-made Jeeps, Cars.com said their domestic-parts content were among the highest figures the web site has observed in this year’s ranking: 74 percent for the Wrangler, 75 percent for the Wrangler Unlimited and 70 percent for the Cherokee.

All engines and nearly all transmissions for the Wrangler and Cherokee originate in the United States, and Fiat-Chrysler assembles both in Toledo.

Globalization is changing how the index is cast, the web site said.

“Over the American-made Index’s 11-year history, the number of models meeting our original criteria has fallen due to the globalization of automobile manufacturing, from more than 60 vehicles in the index’s inaugural year to eight last year,” Joe Wiesenfelder, Cars.com’s executive editor, said in a release.

“By the original requirements, only three 2017 models would have qualified this year. With that, we’ve revamped the (index) to account for the changing landscape and to reinforce factors representing the domestic economic impact when a buyer purchases one model versus another,” he added.

Cars.com said it analyzed more than 100 light-duty passenger vehicles built in the U.S. to arrive at the top 10.
