Bluegrass State's Auto Corridor Centers on Toyota's Largest U.S. Plant
Lexington sits at the heart of Kentucky's automotive corridor — the Toyota Motor Manufacturing Kentucky (TMMK) plant in Georgetown, the world's largest Toyota facility outside Japan, produces the Camry, RAV4 Hybrid, and Lexus ES. The region's Tier 1 supply base includes Toyota Tsusho, Aisin, and DENSO operations, while the University of Kentucky's manufacturing engineering program feeds talent into the local auto supply chain.
RivCut gives Lexington automotive teams fast-turn CNC machining, tight tolerances, and the PPAP documentation Toyota's production system requires on every component lot.
