General Motors has again claimed the top spot in an annual study ranking which vehicles are most American.

The Chevrolet Traverse, Buick Enclave and GMC Acadia are tied for the top spots on the annual Kogod Made in America Auto Index rankings for the second year.

The highest ranked cars are made by U.S. based manufacturers using American engines and transmissions, and with a high percentage of U.S. and Canadian parts.   Here's more from the Detroit Free Press.
