Stellantis announced the closure of the engine factory located in Douvrin, in northern France, with a planned date of October 30, 2026, marking the end of the unit's 57 years of existence. The decision was communicated on July 20.
Engine Plant History
The plant began in 1969, as a result of a collaboration between Peugeot and Renault. Initially, it was responsible for producing the X engine, which was used in various vehicles such as the Renault 14, Peugeot 104 and 205, as well as the Citroën Visa and C15 and Talbot Samba Rallye.
Subsequently, the unit began manufacturing the V6 PRV, used in several French luxury models and also in the DeLorean from 'Back to the Future'. Furthermore, Douvrin assembled the EP and Prince powertrains, the latter developed in partnership with BMW and found in Peugeot and Citroën, from the EP6 Turbo of the DS3 Racing to the 270 hp version of the Peugeot 308 GTI and RCZ R.
The PureTech Engine Issue
In 2012, the three-cylinder EB engine, known as the 1.2 PureTech, was introduced, which used an oil-bathed timing belt. Although this technology promised to reduce friction and consumption, the belt showed degradation due to contact with the lubricant, generating residues that harmed the engine's lubrication. Issues with oil consumption and reliability were attributed to the design and usage standards, such as stop-and-go traffic, and not to the factory's operation.
The response to these issues included recall calls, warranty extensions in Europe, and, starting in 2023, the implementation of a generation with a timing chain instead of a belt. In recent months, the unit was only producing the EB2, the 1.2 version already with a chain, intended for combustion and hybrid models of the group, although this version has been discontinued in Western Europe. The 1.5 BlueHDi engine, another model with a questionable reputation, left Douvrin the previous year.
Reasons for Closure and Future
There are two main factors justifying the closure. The first is that the replacement for the 1.2 PureTech, a new 1.2 turbo engine, will be produced in Trémery, near Metz, where Stellantis plans to finalize the lifecycle of this engine. The second factor is the growing electrification of the region, which is now called the 'battery valley', parallel to Silicon Valley. Near Douvrin operates the ACC gigafactory, a battery supplier for the Peugeot e-3008 and e-5008, and there are expectations that the plant will be adapted for cell production, although the automaker has not yet confirmed this destination.
In terms of labor, Stellantis relocated 340 employees to the adjacent battery operation and offered transition plans for another 330. Fewer than 50 permanent employees and about 50 on part-time contracts are still awaiting a defined destination and require retraining to adapt to the new production chain.
However, the engine that marked Douvrin's recent history will not cease production immediately; the Tychy plant in Poland will continue to manufacture the 1.2 PureTech and is expected to keep it in line for a few more years, targeting markets outside of Western Europe.
