University Town Drives Automotive R&D and Connected-Vehicle Innovation

Ann Arbor is the brain of Michigan's auto industry — the University of Michigan's Mcity autonomous-vehicle test facility, Toyota Research Institute's Ann Arbor office, and a dense cluster of mobility startups make the city a hub for connected and autonomous vehicle development. Tier 1 suppliers including Bosch, Continental, and Hella maintain engineering offices, while legacy machining shops across Washtenaw County serve prototype and production programs.

RivCut supports Ann Arbor automotive teams with rapid prototyping, production machining, and the dimensional precision your AV and EV R&D programs demand.
