STLA Stellantis: Which cars will be equipped with the STLA Large platform

STLA Stellantis platform reveals technical details

Stellantis Group has developed the STLA family of modular platforms to realize its global electrification strategy. The Frame platform is designed to equip vans and pickup trucks, small city cars and compact cars, as well as mid-size station wagons and compact SUVs.

STLA Large is designed for top-of-the-line sedans, crossovers and SUVs. STLA Medium is the first of four platforms that will be launched in July 2023, alongside the launch of the new Peugeot 3008. Now it's the turn of its big sister, the Large, to reveal its secrets through Carlos Tavares' remarks. This is an opportunity to appreciate the cars she will inherit from 2024.

A high-performance, multi-energy platform

The STLA Large platform was developed by the US arm of the Stellantis Group, which includes the Jeep, Dodge and Chrysler brands. It will initially be produced in the US and Italy at the Cassino plant, where the Alfa Romeo Stelvio and Giulia, as well as the Maserati Grecale, are already assembled. We now know that the model's modularity will allow it to measure between 4,764 and 5,126 mm in length and 1,897 to 2,030 mm in width. The wheelbase will range from 2,870 to 3,075 mm. Ground clearance will also vary, ranging from 140 to 288 mm.

Although Stellantis claims that this platform is a "native BEV", it is actually a multi-energy platform, as it is not only intended for electric vehicles. This aspect has already been indirectly revealed with the upcoming Jeep Grand Cherokee, which will be equipped with this platform from 2027 in both electric and electrified (hybrid and/or plug-in hybrid) versions.

So far, Stellantis has revealed the characteristics of its STLA Large platform in an electric configuration. It can be equipped with either 400V or 800V batteries with capacities ranging from 85 to 118 kWh, providing a maximum range of 800 kilometers. In the 800 V configuration, the charging capacity is up to 4.5 kWh. One or two motors can be installed to get a rear-wheel drive, front-wheel drive or all-wheel drive version. In terms of performance, the 0 to 100 km/h acceleration time is claimed to be just 2 seconds for the most efficient cars.

The eight cars will be launched between 2024 and 2026

Stellantis has announced the launch of at least eight models based on the STLA Large platform between 2024 and 2026. The first will be the Dodge Charger EV muscle car, which will be launched in the fall of 2024 in the US. Immediately after that, the Jeep Wagoneer S will become eligible for the new platform. This 600-horsepower XXL electric SUV will go on sale in the US in the fall of 2024 and in Europe the following year. Two Alfa Romeo models will also be equipped by 2026: the Stelvio SUV will be available in fall 2025 and the Giulia sedan in 2026. They will also benefit from the future STLA Brain electric/electronic architecture.

We also know that at least one Chrysler-branded model will utilize this platform. As for the other three models, there are all sorts of rumors. While the group hasn't confirmed anything, it seems likely that the replacement for the Maserati Levante, which is currently being produced at the Mirafiori plant, will be based on the STLA Large.

The same goes for the upcoming Maserati Quattroporte, which will be produced at the same site. As for the eighth model, it could be a Dodge or Chrysler. If the announced schedule does not go beyond 2026, the Grand Cherokee and Alfa Romeo's large SUV should also be based on the STLA Large platform from 2027.
