Stellantis Pratola Serra Plant to Build 2.2L Hybrid Diesel

Stellantis Pratola Serra Plant to Produce New Diesel Engine

On September 29, the FISMIC union announced that the Stellantis Pratola Serra plant in Italy is scheduled to produce a new 2.2-liter Multijet diesel engine with 48V mild-hybrid technology from 2029. The engine will be installed in Ducato commercial vehicles produced at Stellantis facilities in Atessa, Italy, and Gliwice, Poland. The program gives the Pratola Serra facility a defined role in production of a newer powertrain configuration while connecting its output directly to the manufacturing requirements of the Ducato commercial vehicle program across multiple European plants.

48V Mild-Hybrid Technology Supports Efficiency Goals

The new 2.2-liter engine is expected to create additional opportunities for the Pratola Serra plant while supporting improvements in vehicle efficiency and emissions performance. Its 48V mild-hybrid technology represents an evolution of the diesel powertrain rather than a replacement of the combustion engine architecture. According to the announcement, production of the engine at Pratola Serra will support the transition toward newer technologies while maintaining a manufacturing role for the facility. The planned program therefore links powertrain modernization with continued industrial activity at the Italian plant.

Ducato Production Connects Three European Plants

The engine will be used in Ducato commercial vehicles built at the Atessa plant in Italy and the Gliwice plant in Poland. This production arrangement connects the Pratola Serra engine operation with vehicle assembly activities at two separate European locations. The planned supply relationship also provides a direct manufacturing pathway for the new powertrain, with engines produced in Pratola Serra feeding the Ducato program. The development is consequently relevant to multiple facilities involved in producing and supporting the commercial vehicle line.

Verrone Plant Could Benefit From Higher Transmission Production

The Pratola Serra engine program is also expected to benefit Stellantis’ Verrone plant in Italy, which produces transmissions for Ducato vehicles. As engine production increases or becomes integrated into the updated powertrain program, the transmission facility could see additional production opportunities connected with Ducato demand. The announcement specifically indicates that the new engine program could increase production at Verrone and strengthen the plant’s position within Stellantis’ components business. The relationship gives the program an impact beyond engine manufacturing by potentially supporting activity at another Italian component facility.

Industry Impact & Outlook

The planned 2.2-liter Multijet diesel engine program gives Stellantis a path to introduce 48V mild-hybrid technology into Ducato production while maintaining manufacturing activity across its European industrial network. The most direct effects are expected at Pratola Serra, Atessa, Gliwice, and Verrone, where engine, vehicle, and transmission operations are connected through the commercial vehicle program. The announcement also indicates that newer powertrain technology can support continued roles for established manufacturing facilities. The next important steps will be implementation of the production program ahead of its planned 2029 start and the resulting production requirements for the facilities involved.

Frequently Asked Questions

What engine will Stellantis produce at the Pratola Serra plant?
The Pratola Serra plant is scheduled to produce a new 2.2-liter Multijet diesel engine with 48V mild-hybrid technology beginning in 2029. The engine is planned for Ducato commercial vehicles manufactured at the Atessa plant in Italy and the Gliwice plant in Poland. The program is expected to support improved efficiency and reduced emissions while introducing newer powertrain technology. It could also benefit Stellantis’ Verrone plant, which produces transmissions for Ducato vehicles, by increasing production opportunities and strengthening the facility’s role within the company’s components business.
