Renault Group is developing its Busan production plant as a key production base for its future vehicle strategy in Asia, as the automotive industry in South Korea transitions towards electrification and software-defined technologies.

In its recently announced medium- to long-term vision, futuREady, Renault Group identified the Busan plant as its largest production base in Asia and a "multi-energy production hub" capable of building combustion, hybrid and electric vehicles on a single production line.

The plant, which broke ground in the mid-1990s with access to Korea's largest port infrastructure and a skilled manufacturing workforce, has more than 30 years of manufacturing history. Samsung Motors began construction of the plant in 1995, the first SM5 rolled off the production line in 1998, and Renault Group acquired the operation in 2000. Production experience and manufacturing technology have continued to develop since then.

The Busan plant can assemble up to eight models on a single production line and handle vehicles with different power sources within the same production setup. This allows the plant to adjust the models it produces and their volumes in response to changes in market demand. The facility is also being developed to produce next-generation software-defined vehicles (SDVs) and battery electric vehicles (EVs), expanding its role within Renault Group's future vehicle production plans in Asia.

The models produced in Busan include the Filante and the Grand Koleos. The Filante features infotainment systems including an AI-based digital experience and the OpenR panoramic display. The model is designed for SDV applications, in which software and digital functions form part of the vehicle alongside hardware. The plant is also producing and exporting models for international markets in addition to serving the domestic market.

Busan's production and quality performance has also been assessed over several years. In Renault Group's assessments of its global plants, Busan has ranked highly for several years on quality metrics such as defects per 100 vehicles and defects per vehicle shipped. The plant ranked eighth in 2016 and seventh in 2017 in the Harbour Report, which compares productivity at automotive plants worldwide.

The plant also produced the Nissan Rogue under a contract production arrangement for export to North America, receiving recognition for quality and being allocated additional production volume. Its production system allows it to manufacture a range of models rather than dedicating equipment to a single model.

The production system is relevant to Renault Group's manufacturing strategy in Asia as automotive markets continue to adopt different powertrain technologies at varying rates. The transition towards electric vehicles continues, but the pace differs between regions and markets. For automakers, concentrating production facilities on a single powertrain can increase the risk that large-scale equipment investments become less useful if demand changes. Production systems that allow manufacturing capacity to be adjusted according to market conditions can therefore reduce the need to allocate capacity exclusively to combustion, hybrid or electric vehicles.

The Busan plant can produce vehicles with different powertrains on a single line using existing equipment. It can also adjust the models produced and their volumes according to demand, while reducing the need to establish a separate large-scale production line when a new model is introduced. This production system allows manufacturing capacity to be adjusted during the transition towards electrification.

Renault Korea is developing the Busan facility as a smart factory by expanding AI-based real-time quality inspection, automated equipment and digital production systems. The company plans to upgrade the production system for future vehicles, unveiling a next-generation SDV incorporating AI technology in 2027 and beginning mass production of a next-generation battery electric vehicle in 2028. The programme includes changes to production processes based on AI and data, in addition to flexible production of different models and power sources.

The development of the Busan plant is also expected to affect the automotive industry in the surrounding region. As vehicle production shifts towards SDVs and electric vehicles, local parts manufacturers may need to expand from mechanical and combustion-focused products to electronic components, software and electrification-related parts. The plant's transition to future vehicles is expected to involve technology development and equipment investment among suppliers, affecting the Busan automotive industry ecosystem.

The plant's production capabilities include its location next to a port, production flexibility, quality management and AI- and digital-based manufacturing systems. These capabilities are being incorporated into its development as Renault Group's largest production base in Asia.

"The Busan plant is a core Renault Group asset that has proven its quality management capability and production flexibility over decades," a Renault Korea official said. "Along with taking flagship models built in Busan into global markets, we will work to help upgrade the regional auto industry ecosystem around future vehicles."
