Chrysler, Fiat, PSA: on the birth of Stellantis in 2021 (born from the merger of Fiat-Chrysler with PSA), the newly created Franco-Italian-American group had to fundamentally reorganize its entire industrial apparatus. A pool of teams, resources and technologies, sharing costs and risks, the goal was to develop low-cost models for each of the 14 brands in this vast automotive galaxy. And means of combining technologies share your engines, your gearboxes, but also and above all its platforms. You know, the foundation on which the entire structure of the car rests. At that time there were 14 of them : 7 at Chrysler, 5 at Fiat and 2 at PSA (CMP and EMP2). Most of the group’s models, with the exception of the latest new products, are still based on these rather old structures.

Four common platforms in the future

Eventually, the group will build all of its models four common platforms called STLA Small, STLA Medium, STLA Large and STLA Frame, suitable for both thermal and electric models. There Averageyou know it for sure: it was launched at the same time as the new Peugeot e-3008, the first model of the group to benefit from it. The future Citroën C5 Aircoss, Jeep Compass and Opel Grandland will also have the right to it. In anticipation of Small, reserved for B and C segment models, and Frame (ladder chassis and non-self-supporting), which will equip the next generation of pickups and “trucks” from Jeep and RAM, Stellantis presents today first information about the STLA Large platformwhich will equip large SUVs, sedans and 4X4s in the D, E and F segments…

STLA Large, the most ambitious platform.

It is a platform that should allow the group launch of high-class electric models, with great autonomy and high charging capacity. In fact, its modularity will accommodate large vehicles: up to 5.13 m long2.03 m wide, 3.07 m wheelbase and 28.8 cm ground clearance! Dodge, Jeep, Maserati, Alfa Romeo and Chrysler win, which ditches DS in favor of Alfa Romeo as the group’s first premium brand. Batteries, 400 V or 800 V depending on the configuration, will have capacity from 85 to 118 kW/h, and will be able to accept to Charging power 270 kW. Stellantis, however, has been tight-lipped about offering engines for this platform, but we do know that in addition to electric models, it will also be able to accommodate thermal and hybrid models. Eight are planned between 2024 and 2026…
