Hyundai America Technical Center Inc. is investing $5 million in the American Center for Mobility near Ann Arbor, Mich.
The investment brings the autonomous vehicle testing site's fundraising total to $101 million out of the total project cost of $135 million, according to a Tuesday news release.
The mobility center bumped up its total cost estimate from a previous $110 million as "we increased the scope (of the project) based on input from investors and are working to meet their needs," ACM CEO John Maddox said in an emailed statement.
Ford Motor Co. invested $5 million in September, following Toyota Motor North America, which was the first automaker to invest. Toyota contributed $5 million in July.
Hyundai America Technical Center in neighboring Superior Township is an r&d facility for Hyundai Motor Group's North American design, technology and engineering divisions.
The automaker has signed on as a founder-level sponsor of the American Center for Mobility. It will join the nonprofit's government-industry team, which will work to create government standards and regulations; it will also be able to test its own connected vehicle technologies there, according to the release.
Hyundai plans to test sensor technology, communication between vehicles and infrastructure and how connected vehicle systems work in inclement weather, the release said.
Construction on the 500-acre site began last November at General Motors' former Willow Run assembly plant.
The first phase of construction, expected to be complete in December, includes creation of a 2.5-mile highway loop with on- and off-ramps, a 700-degree curved tunnel, a customer garage and an operations center. Phase two construction is to start in July, Maddox told Crain's Detroit Business in July.
