The American Center for Mobility (ACM) is a 500-acre (200 ha) vehicular automation research center and federally designated[2] automated vehicle proving ground[3] located in Ypsilanti Township, Michigan.

Portions of the US Highway 12 alignment and ramps to the former manufacturing complex were repurposed for creation of a test track.

The test track includes a 700-foot (210 m) curved tunnel, 2.5-mile (4.0 km) highway loop, an off-road course, two double overpasses, along with various intersections and roundabouts.
