Alabama's Auto Assembly Boom Transforms the Magic City
Birmingham anchors Alabama's automotive corridor — the Hyundai Motor Manufacturing Alabama plant in Montgomery (90 minutes south) produces Sonata, Elantra, and Santa Cruz, Honda Manufacturing of Alabama in Lincoln builds the Pilot, Passport, and Ridgeline, and Mercedes-Benz U.S. International in Tuscaloosa assembles GLE, GLS, and EQS SUV models. The metro's deep metals and steel heritage provides a natural machining talent pool.
RivCut serves Birmingham automotive teams with CNC machining, production-run capacity, and the PPAP documentation Hyundai, Honda, and Mercedes-Benz quality systems require.
