(June 27, 2013) CHICAGO — Cars.com announced this week that the Ford F-150 has topped the site's American-Made Index. This is the first time in four years that a domestic automaker is once again the "Most American."

Prior to the F-150's top spot, the Toyota Camry topped the list from 2009-2012. The list is determined by analyzing three data points; domestic-parts content (percentage of vehicle's parts produced in the U.S.), final vehicle assembly point and vehicle sales.

"Strong sales and 75 percent domestic-parts content propelled Ford's popular F-150 to the top of the index for 2013, a rank it held from 2006 to 2008," said Patrick Olsen, Cars.com's editor-in-chief.

"Ford's top ranking this year is a good indicator of how pickup trucks are dominating auto sales so far in 2013, and how the domestic automakers are bouncing back. While the assembly point and domestic parts content of the F-150 didn't change from 2012-2013, vehicle sales are responsible for bumping the F-150 to the top spot."

While the Toyota Camry is no longer the highest ranked on the list, Toyota still remains the brand with the greatest number of vehicles ranked. As was the case in 2012, the list remains an even split between foreign-owned and domestic-owned automakers, with five domestic brands and five foreign brands on the list. In addition to Toyota's four vehicles on the list, General Motors has a total of three. Chrysler, Ford and Honda each have one vehicle on the list.

 "Buying American isn't necessarily the key decision maker for every car shopper; however a study we conducted in 2012 indicated that 25 percent of shoppers surveyed preferred to buy American," said Olsen. "The American-Made Index is meant to help car shoppers understand that 'American-Made' extends beyond just the Detroit three."
