(April 21, 2014) DETROIT — For the second year in a row, General Motors dominated the “Made in America” Automotive Index produced by American University’s Kogod School of Business. GM’s Chevrolet Corvette Stingray tied for No. 1 and 17 other GM vehicles tied for places in the Top 10.

In addition to the Stingray, seven other Chevrolets made the Top Ten including: Traverse, Equinox, Express, Malibu, Impala, Suburban and Tahoe. Other GM vehicles that ranked in the Top 10 were the GMC Acadia, Acadia Denali, Terrain, Savana and Yukon; Cadillac CTS, Escalade and ATS and Buick Enclave and LaCrosse.

The index is authored by Frank DuBois, a global supply chain management expert and professor at American University. DuBois developed the list based on data from the National Highway Traffic Safety Administration along with the location of headquarters, design, research and development, and where the profits go.

More comprehensive than other studies of its kind, the Kogod index ranks 318 car models based on seven weighted data points. These criteria include several factors, unaddressed by the American Automotive Labeling Act, which is the basis for “made in America” automotive studies:

    Profit Margin: Location of the automaker’s global headquarters
    Labor: Location of assembly
    Research & Development: Location of R&D activities
    Transmission: Location of production
    Inventory, Capital and Other Expenses: Location of assembly
    Engine: Location of production
    The Labeling Act “Domestic Content” Score

Based on the Labeling Act, if 75 percent of a vehicle’s value or more of a car’s parts come from the U.S. or Canada, it’s considered a domestic product. Nearly 80 percent of Americans would rather buy an American-made product, according to a Consumer Reports National Research Center survey. Furthermore, a recent 2013 Consumer Reports article pointed to the 2013 AU/Kogod study as the study to use when trying to decipher which vehicles are American made.

“This index undoubtedly provides Americans with a more defined explanation of the actual origin of a vehicle and its purchasing impact on the U.S. economy,” said Gerald Johnson, GM North America Manufacturing vice president.
