Hyundai is putting approximately $450 million into its Montgomery, Alabama manufacturing plant, with production of the all-new Tucson set to begin before the end of 2026 and a direct push into Extended Range Electric Vehicle technology on the way.
The investment, announced today at HMMA by president and CEO Mark Rader alongside Alabama Gov. Kay Ivey and Korean Ambassador Kyung-wha Kang, brings Hyundai’s total capital commitment to the Montgomery facility to nearly $2.2 billion since production started there in 2005. It also slots into the Hyundai Motor Group’s broader $26 billion U.S. investment pledge covering 2025 through 2028, first outlined by group president and CEO José Muñoz late last month.
The package has three main pieces. First, new engine production capabilities, including hardware for hybrid-electric and EREV applications. Second, preparation for the all-new Tucson, which will go into production at the plant before year-end. Third, tooling and infrastructure for a refreshed Santa Fe.
The Tucson production shift matters more than it might look on the surface. Today, HMMA builds only the internal combustion version of the Tucson. Tucson Hybrid models sold in the United States are imported from South Korea. Bringing Tucson Hybrid production to Montgomery effectively closes that gap and gives Hyundai more domestic production leverage in a market that is increasingly rewarding it. The plant currently runs at roughly 360,000 vehicles per year for North America.
The EREV thread is the one worth watching on the technology side. Extended Range Electric Vehicles pair a battery-electric drive system with an onboard generator, typically a small combustion engine, to extend range without the packaging constraints of a large battery pack. Hyundai has not announced specific output figures or battery capacity for the EREV powertrain coming to Montgomery, but the investment in new manufacturing infrastructure suggests this is production-intent engineering, not a skunkworks exercise.
Powertrain flexibility is the throughline across the full investment. Adding hybrid and EREV engine variants to the Montgomery production mix gives HMMA the ability to shift output mix as demand moves, rather than being locked to a single propulsion type. For a plant building 360,000 vehicles a year, that flexibility has real operational value.
Hyundai has not announced a timeline or model application for the EREV production program beyond the general commitment to Montgomery.
The political backdrop of today’s event was deliberate. Ambassador Kang framed the investment as an expression of the South Korea-United States economic alliance, and Gov. Ivey used the announcement to reinforce Alabama’s position in the automotive manufacturing landscape. The Montgomery plant employs 4,200 people and anchors a regional supply chain that extends well beyond the assembly floor.
Bringing Tucson Hybrid production stateside while layering in EREV infrastructure gives Hyundai a more resilient North American production base. The question is how quickly the EREV program moves from plant-prep to actual vehicles rolling off the line.
