Hyundai reshapes vehicle production at Metaplant America
Hyundai Motor Group’s manufacturing complex in the US state of Georgia embodies the next generation of software-defined and flexible production for the future of electric and hybrid vehicle assembly
Hyundai Motor Group is at the vanguard of the vehicle manufacturing evolution at its new $7.6 billion facility in Ellabell, in the US state of Georgia. Hyundai Motor Group Metaplant America (HMGMA) is a software-defined factory which brings together Hyundai Motor Group’s advanced manufacturing capabilities and integrates AI and robotics automation.
The electric and hybrid vehicle plant is currently making the Hyundai Ioniq 5 and Ioniq 9 EVs, as is about to add the Kia Sportage hybrid to its production line. Its annual target at full capacity is to produce 500,000 EV and hybrids for the Hyundai, Genesis and Kia brands, with a production mix across 10 different models.
At the official opening of HMGMA in March last year, Euisun Chung, executive chair of Hyundai Motor Group, said the facility was a showcase for the carmaker’s advanced manufacturing capabilities and commitment to innovation. That is clear in the cutting-edge robotics and vision systems it has in place, designed to ensure high-quality and flexible vehicle production with robots assisting human workers to improve efficiency. Those human workers will number 8,500 by 2031.
Robust supply chain
Underpinning vehicle production is a robustly integrated and localised supply chain. That includes an on-site battery manufacturing facility, which is a joint venture between Hyundai and LG Energy Solution, called HLBMA (formerly HL-GA Company). Battery cells are fed into that plant from the Bartow County facility run by SK On with which Hyundai has a 50:50 agreement, bringing total investment to $12.6 billion, the largest investment in the state’s history.
The carmaker has also committed to spending $6 billion to localise parts and strengthen logistics, as well as investing in US steel production. That investment includes digital technology used to connect and optimise processes from order collection, procurement, logistics and production. The carmaker says it will strengthen Hyundai Group logistics to “ensure robust supply chains” in the US.
The level of commitment Hyundai and its supply chain partners are investing in is additionally impressive given the volatile market for battery electric vehicles (BEVs), notably since the removal of incentives by the Trump administration in September last year. Again, the flexibility built into the assembly line means Hyundai has been able accommodate hybrid production with little interruption to assembly.
Hyundai says its core strategy has not changed despite the removal of US EV tax incentives and to align production with market demand and policy conditions. It says it is adjusting the mix of EVs, hybrids and internal combustion engine (ICE) vehicles as needed, but without altering its long-term electrification investment outlook.
The integration of robotics and vision lend themselves very well to applications where an assembly operation requires using vision data to precisely position a component to the vehicle
Precision robotics
As mentioned, HMGMA is the innovation flagship for Hyundai. The plant has scaled up advanced manufacturing technologies developed and validated at the Hyundai Motor Group Innovation Center Singapore (HMGICS) for mass production. It integrates AI, robotics and data technologies and Hyundai has established an automated production system where all processes, from order collection and procurement to logistics and assembly, are connected.
The plant was built to embrace technology and support a safe and technologically advanced workplace for its employees, known as ‘Meta Pros’. Hyundai says that automation and technology are used at the plant to boost efficiency and replace repetitive and hazardous tasks, thereby enhancing productivity, reducing physical injury and providing a better overall work environment.”
Automated vehicle assembly applications at HMGMA are strategically planned to target operations that require a high level of precision or that are particularly difficult for people to do.
“The integration of robotics and vision lend themselves very well to applications where an assembly operation requires using vision data to precisely position a component to the vehicle,” says Jerald Roach, head of department for general assembly at HMGMA. “In addition, robotics and vision can be used to perform repetitive tasks that are beyond the physical limitations for humans. By choosing the right applications to apply these technologies, HMGMA has achieved the integration of a high number of successful technologies in volume production.”
Atlas applications
Hyundai is not sharing details of the assembly equipment providers at HMGMA, many of which are group affiliates (see box). However, Boston Dynamic’s Atlas humanoid robots are scheduled for deployment in January 2028. The Atlas humanoid has moved from a prototype into a production-ready industrial robot and is now being built at the company’s Boston headquarters.
At HMGMA it will first be used in the external scheduling area for unloading and sorting inbound parts and will focus on packaging boxes with large or heavy components that are difficult for humans to handle.
In October last year Hyundai tested the Atlas robot with the task of sorting roof racks for the assembly line. Using a machine learning process an engineer wearing a virtual reality headset takes direct control of Atlas and guides its hands and arms through each task until it is learned. The data generated can then be used to train the robots AI models to do the task autonomously.
The commonality of parts on Atlas and a fastidious but robust design are important for the demands of automotive manufacturing. That includes the position of the battery externally on the Atlas robot so that it is able to replace its own battery, supported by fast-charging technology for a fleet of robots in a factory setting.
The robots range of motion must also comply with safety priorities when working alongside humans in a factory or warehouse. This is where Atlas’ camera technology and the flexibility of its head play an important part. The field view of the cameras enable the robot to see its environment and the parts of its body, and where it is in space.
Battery feed
As indicated, EV battery cells are being supplied from the on-site facility operated by HLBMA. Those battery cells are delivered to Mobis Battery System Assembly which packages them together on the skateboard chassis, which then goes into the HMGMA assembly area by conveyor. There is a second Mobis facility onsite (Mobis Module) that produces the front end module for the vehicle.
“At HMGMA the feeding and marrying of battery sub-assemblies’ is done via a highly automated process,” says Roach. “Automation ensures repeatability and precision required to ensure that critical components such as the front suspension, drive system, rear suspension and battery subassembly are precisely positioned to the underbody and that all fastening is controlled for presence and proper torque.”
“We maintain common locating schemes for our major components so that the automation is easily modified to accept new models whether they be internal combustion engine, battery electric or hybrid powertrains
This is where HMGMA differs from more traditional automotive assembly lines, having been designed and built specifically to optimise the assembly of BEVs. According to Hyundai, the marriage of a large battery to the underbody of the vehicle must be considered up front in not only the design of the factory, but also in the design of the vehicle.
“Plants that are specifically designed to build ICE vehicles are forced to undergo significant structural modifications, or to make compromises in assembly process and/or vehicle design to address fundamental BEV differences,” says Roach.
The modular design of Hyundai’s vehicles also plays its part as an enabler for the flexibility required to build a variety of powertrain combinations in a single plant.
“We maintain common locating schemes for our major components so that the automation is easily modified to accept new models whether they be internal combustion engine, battery electric or hybrid powertrains,” adds Roach.
Safety on the line
As with any vehicle assembly plant, the priority is getting the right parts to the right place at the right time. Hyundai is using automated material delivery systems including automated guided vehicles (AGVs) and automated trailer unloading systems. In doing so it is avoiding much of the material delivery safety concerns associated with tuggers and forklifts, which it says makes for a safer and more efficient assembly plant.
“An aggressive kitting strategy is employed for the distribution of sequenced parts to the point of use which increases our flexibility for multiple vehicle models and reducing the number of decisions our Meta Pros are required to make as part of the assembly process,” explains Roach. “The lack of a high number of parts displayed lineside improves our overall visual management of our assembly operations.”
AGVs are also used for moving the vehicles along the assembly line, rather than traditional rigid conveyors. Those AGVs move on programmed paths guided by QR codes on the factory floor.
Sustainable horizon
Some of HMGMA’s sustainability measures include renewable energy sourcing and solar generation, an energy efficient facility design and reduced emissions through electrified vehicle production. The facility also has an advanced wastewater treatment and management system. Water conservation measures include reclaimed water usage for landscaping and stormwater collection and controlled release.
Hyundai Motor Group signed a 15-year power purchase agreement with energy development company Matrix Renewables in 2024. It has bought 147 MW of generation capacity from Matrix Renewables Stillhouse Solar Project in Texas. Hyundai expects to secure approximately 378 GWh of electricity annually and anticipates an annual reduction of 140,000 tons of carbon emissions across its US facilities.
Looking ahead, Hyundai remains confident in the future of BEV manufacturing in the US. Roach says the company will continue to invest in local production capacity, viewing electrification as a long-term growth driver supported by localisation, scale and consumer choice, even as near-term policy dynamics evolve.
