The modern automotive landscape didn’t arrive overnight. It is the result of decades of mergers, engineering decisions and shifting market demands — and few groups illustrate that evolution better than Stellantis.
What exists today as a single global manufacturer is, in reality, the product of multiple historic brands coming together over time. Peugeot, Citroën, Vauxhall and others were not designed to operate as one, but changing economic pressures, rising development costs and the transition to electrification made consolidation inevitable.
The early foundations: Peugeot and Citroën
The story begins with two of France’s most important automotive manufacturers. Peugeot, established in the 19th century, built its reputation on durable, practical vehicles, while Citroën, founded in 1919, became known for innovation and unconventional engineering.
By the 1970s, Citroën was facing financial difficulties, and in 1976 Peugeot acquired a controlling stake, forming what became PSA Group. The merger was driven by necessity — combining resources allowed both brands to survive and compete more effectively in a growing European market.
This partnership laid the groundwork for a new way of building vehicles: shared engineering, shared platforms and a focus on efficiency without sacrificing identity.
PSA Group and the rise of practical vehicle design
Under PSA, Peugeot and Citroën began developing vehicles using shared platforms, a strategy that would define the group for decades. This approach allowed them to reduce costs while maintaining distinct branding across each manufacturer.
It was particularly effective in the commercial vehicle sector. Vans such as the Citroën Berlingo and Peugeot Partner became widely adopted across Europe, offering a balance of compact size and practical load space that suited both business and personal use.
These vehicles weren’t just successful commercially — they helped redefine expectations of what a small van could be, combining usability with everyday drivability.
Expansion into mid-size vans
As demand grew, PSA expanded its range into larger commercial vehicles. This led to the development of mid-size vans such as the Citroën Dispatch, designed to offer greater load capacity while remaining manageable on the road.
These vans followed the same principles: efficient packaging, shared engineering and adaptability across different use cases. They became particularly popular among trades, fleet operators and later, private owners seeking multi-purpose vehicles.
The acquisition of Opel and Vauxhall
A major turning point came in 2017, when PSA Group acquired Opel and Vauxhall from General Motors. This move significantly expanded PSA’s presence across Europe and gave it access to new markets and manufacturing facilities.
It also brought additional models into the shared platform strategy. Vehicles such as the Vauxhall Vivaro became part of the same engineering ecosystem, further strengthening PSA’s position in the commercial vehicle market.
The acquisition was driven by scale. As development costs increased — particularly around emissions and new technologies — larger production volumes became essential.
The formation of Stellantis
The next major step came in 2021, when PSA Group merged with Fiat Chrysler Automobiles to form Stellantis.
This was not simply a merger of brands, but a strategic response to the future of the automotive industry. Electrification, software integration and global competition required a level of investment that few companies could sustain independently.
By combining PSA’s European engineering with FCA’s global reach, Stellantis became one of the largest automotive manufacturers in the world almost instantly.
The merger also allowed for greater sharing of platforms, technologies and development resources across an even wider range of vehicles.
A shared engineering philosophy
Despite the scale of these changes, one principle has remained consistent: efficiency through shared design.
Whether it is a compact van or a larger commercial vehicle, many models within the Stellantis group are built on common platforms. This allows different brands to produce vehicles that feel distinct, while benefiting from the same underlying engineering.
This approach has been particularly effective in the van market, where durability and usability are more important than brand differentiation alone.
The role of these vehicles today
The vehicles developed under PSA — and now Stellantis — continue to play a major role in how people use and think about transport.
Compact vans like the Berlingo and Partner are now widely used beyond their original commercial purpose, often adapted for travel and leisure. Mid-size vans such as the Dispatch and Vivaro offer increased capability while retaining everyday usability.
This flexibility is a direct result of the design philosophy established decades ago: build vehicles that are practical, adaptable and efficient.
A connected automotive ecosystem
Understanding how these vehicles relate to one another can be complex, given the number of brands and models involved. For a broader view of how different platforms and vehicles fit together, the full range of models and supporting pages provides a useful overview of the wider ecosystem.
Conclusion
The history of Stellantis is not the story of a single brand, but of an industry adapting to change. From the early partnership between Peugeot and Citroën, through the expansion of PSA Group and the acquisition of Vauxhall, to the formation of a global manufacturer, each step has been driven by the same need: to build vehicles more efficiently, at greater scale and for a wider range of uses.
Today, Stellantis represents the culmination of that process — a manufacturer shaped by decades of collaboration, engineering and evolution, built on the foundations originally established by PSA Group.
