Stellantis brings 280-plus suppliers and startups to 2026 Factory Booster Day for plant innovation

The 2026 Factory Booster Day

Stellantis held its 2026 Factory Booster Day on 21 October, connecting manufacturing challenges raised by 63 of its plants with proposals from more than 280 suppliers and startups. Over 80 of those proposals were selected to present work spanning artificial intelligence, automation, advanced robotics, vision systems, intelligent energy management and digital manufacturing tools, as reported by Automotive World, citing Stellantis, and separately by Affari Italiani. ¹²

The event is a global initiative centred on technologies intended to improve quality, efficiency, safety and sustainability in automotive production. Affari Italiani notes that the aim is not simply to showcase new tools, but to identify applications that can be transferred concretely into production departments, where results and shortcomings can be verified on the ground. ²

New features of the 2026 edition included Beyond the Booths sessions dedicated to priorities outlined by Stellantis executives, and Innovation Global Awards recognising the most relevant contributions from employees and plants across regions. Affari Italiani reports that the announcement does not name the award recipients or provide an overall quantitative assessment of the edition. ²

How the Open Challenge format works

The programme uses an Open Challenge process and has been run annually since 2016. Problems emerge in the plants themselves, and partners develop targeted solutions that are then evaluated for possible industrial use. Both Automotive World and Affari Italiani describe the process as starting from real operational needs rather than technology promises, an approach intended to shorten the distance between experimentation and application on production lines. ¹²

Projects that succeed are readied for rollout across Stellantis's manufacturing network, and the company links the programme to its FaSTLAne 2030 strategic plan. The core value proposition, as Affari Italiani explains, is that a solution proven in one plant becomes more valuable when it can be replicated in others, which is why Stellantis looks for projects adaptable to different lines and contexts. ¹²

Francesco Ciancia, Chief Manufacturing Officer at Stellantis, said: "Factory Booster Day reflects the power of collaboration between our manufacturing teams and supplier partners. By starting from real plant challenges and focusing on solutions that can be deployed at scale, we are accelerating innovation where it matters most: on the shop floor." ¹

What earlier editions delivered: Sterling, Zaragoza and Sochaux

Earlier editions illustrate the model at work. At the Sterling Stamping plant in Michigan, the industrial AI specialist ThinkDigits introduced real-time monitoring of blank draw-in, the movement of sheet metal into the die, allowing stamping deviations to be caught sooner and the process to be corrected more quickly when it drifts from expected parameters. Stellantis says the project saves almost four times its initial cost each year and has prompted an extension to more lines. ¹²

Affari Italiani cautions that the Sterling saving figure relates to that specific application and does not amount to a forecast valid for all Stellantis plants. That qualification is worth keeping in mind when assessing the broader programme's claims, as is the case for the other cited projects. ²

At Zaragoza in Spain, Zeiss brought fixtureless geometry checks for stamped parts, removing the need for dedicated control fixtures and making verification more flexible for different components. Stellantis signals operational advantages with contained implementation costs, but Affari Italiani notes no economic values or measurement-time data were provided. ¹²

At Sochaux in France, Uptale developed immersive digital training modules and virtual line tours, replacing paper-based instruction and allowing workers to learn processes remotely. Affari Italiani characterises this as innovation in skills rather than machinery, changing how employees learn factory procedures. ¹²

Adoption status and what it means for buyers

The report on the event, based on Stellantis's announcement, does not say that any of the 2026 proposals have been adopted across the network; projects require evaluation before adoption, as Affari Italiani emphasises. Participation figures therefore indicate the scale of engagement with suppliers and startups, not the number of technologies already installed in Stellantis plants. ¹²

Stellantis's stated objective is to extend the most effective solutions to different plants, verifying their results in quality and production efficiency, in support of industrial processes capable of meeting customer expectations. For buyers, the programme sits behind the scenes: it concerns manufacturing cost, quality control and training practices rather than specific vehicle specifications, and no vehicle model, variant or market rollout is part of this announcement. ²

Three distinct improvement paths emerge from the cited case studies: process control through data, more flexible geometric measurement, and digital training. Whether the 2026 cohort follows the same trajectory from plant trial to network-wide deployment will depend on the evaluation process that follows the event. ¹²
