Are the Peugeot Boxer and Fiat Ducato the same? Shared parts and the engine split
Sevel and the Atessa plant
Fiat and PSA founded Sevel in 1978 to build light commercial vehicles together, and its Italian plant began production in 1981. The first van was sold as the Fiat Ducato, the Peugeot J5, the Citroën C25, the Talbot Express and the Alfa Romeo AR6. The European vans still come from the Sevel Sud plant at Atessa, in the Val di Sangro in central Italy, which built its six millionth vehicle, a Ducato, in September 2018.
Peugeot and Citroën renamed their versions Boxer and Jumper with the second generation, sold from 1994. Fiat and PSA ran Sevel as a joint venture until 2021, when their merger into Stellantis put the plant and all three brands under one owner.
The Peugeot Boxer and Fiat Ducato share the body and chassis
Within each generation, the body shell, the cab, the doors, the chassis and the running gear are one design across the badges. A Boxer, a Jumper and a Ducato of the same generation take the same panels, glass, suspension and brakes, and the grille, the badges and some trim carry the brand.
The family is larger than three badges. Since 2021 the van is also the Opel and Vauxhall Movano, and since the 2014 model year it has been sold in North America as the Ram ProMaster, with a 3.6-liter Pentastar V6 gasoline engine of its own. The smaller Expert, Jumpy and Scudo came from a second plant, Sevel Nord in France, which opened in 1993.
Engines: PSA diesels and Fiat Multijet
The engines are where the badges split. In the second generation, Peugeot and Citroën versions used PSA diesels such as the XUD9, DW10 and DW12, while the Ducato used Fiat and Sofim engines. In the third generation, launched in 2006, the Boxer and Jumper had a Ford-designed 2.2 HDi, while the main Ducato diesel was the Iveco-built 2.3 Multijet. The 3.0 HDi and the 3.0 Multijet were the same Iveco unit under two names.
The fourth generation, from 2014, kept the split. With Euro 6 at the end of 2016, the Boxer and Jumper took a 2.0 diesel based on the PSA DW10, replaced in 2019 by a 2.2 based on the DW12, while the Ducato kept its 2.3 Multijet. From 2024, all European versions of the van moved to the same 2.2 Fiat engine, built to Euro 6e.
So a 2017 Boxer with the PSA 2.0 and a 2017 Ducato with the 2.3 Multijet share a body but run different engines. Filters, injectors, timing parts and sensors follow the engine code, which the VIN build gives you.
Two catalogs for one van
The parts data sits in two systems. Peugeot and Citroën versions are cataloged in Service Box, and the Fiat Ducato in ePER, the Fiat catalog. Each lists the van under its own brand, so look up a Boxer in Service Box and a Ducato in ePER, and compare the two when you want to cross a part between them.
On VINsearch both open behind one login: Service Box through the Peugeot parts catalog and ePER through the Fiat parts catalog. Our guide to ePER explains how the Fiat side is organized.
Crossing a part between Boxer and Ducato
For body and chassis parts, the Ducato is a good place to look when a Boxer part is on back order. Look up the part on the Boxer’s VIN in Service Box, find the same position on a Ducato of the same generation and build period in ePER, and compare the descriptions and the diagrams before you fit anything.
For engine parts, start from the engine code rather than the badge. A Ducato part fits a Boxer engine only in the years when both vans carried the same unit.
Motorhomes built on the Ducato or the Boxer keep the base van’s parts list for the cab and chassis. Use the VIN of the base vehicle, since the converter’s own equipment sits outside the carmaker’s catalog.
Frequently asked questions
Are the Peugeot Boxer and Fiat Ducato the same?
Yes. They are the same van from the same factory, with a Citroën Jumper version as well. They share the body and chassis, and used different diesel engines for most years until 2024.
Will Ducato parts fit a Boxer?
Body and chassis parts from the same generation usually do. Engine parts depend on the engine each van carries, so compare both catalogs before you fit anything.
Where is the Fiat Ducato made?
European vans come from the Sevel Sud plant at Atessa, Italy. Sevel was the joint venture of Fiat and PSA, and it has belonged to Stellantis since 2021.
What engine does a Peugeot Boxer have?
It depends on the year. Third-generation Boxers used a 2.2 HDi and a 3.0 HDi, fourth-generation Boxers from late 2016 a PSA 2.0 and from 2019 a PSA 2.2, and vans from 2024 a 2.2 Fiat engine. The VIN build confirms the engine code.
