Stellantis STLA-Medium Platform: Flexible and Swift Up to 700 Kilometers

Two years after its presentation at "EV Day" in July 2021, the Stellantis Group has unveiled the so-called STLA Medium platform. The global, purely electric vehicle platform is designed to offer a range of 700 kilometers, high energy efficiency, performance, and charging capability. It will be used for multiple vehicles and drive configurations in the C- and D-segment – the core of the vehicle market, as the group notes. Around 35 million vehicles, nearly half of the total 78.5 million vehicles sold worldwide in 2022, fall into this category. Currently, 26 different vehicle types from various brands based on different platforms are offered in this segment. Up to two million vehicles per year could be built on the STLA Medium platform in several plants worldwide, according to the manufacturer. Production is expected to start in Europe later this year.

"What we see today is the result of more than two years of uncompromising innovation – with the goal of enabling clean, safe, and affordable mobility, supported by investments of 30 billion euros in electrification and software by 2025," enthuses Carlos Tavares, CEO of Stellantis.

STLA Medium is the first of the four global BEV platforms. These are the basis for the company's future products and are key to achieving its ambitious goals. This includes reaching a 100% battery-electric passenger car share in Europe and 50% in passenger cars and light commercial vehicles in the United States by 2030. CO2 emissions are to be halved by 2030 compared to 2021, and the goal of net-zero CO2 emissions is to be reached by 2038. The remaining emissions (in the single-digit percentage range) are to be offset.

Performance or Standard Package

The platform is tiered: The performance package aims for an electric range of more than 700 kilometers, while the standard package enables a range of more than 500 kilometers (WLTP). With a usable energy of up to 98 kilowatt-hours (kWh), the platform is to set the standard in terms of "Embedded Power," meaning the power transferred to the wheels. However, it continues to be based on a 400-volt battery, which is intended to have high energy efficiency, charging time, and connectivity to a charging and service ecosystem. Depending on usage, consumption could be less than 14 kWh per 100 kilometers, as promised. The battery can be charged from 20% to 80% in 27 minutes. This corresponds to 2.4 kWh per minute.

Global Distribution

Vehicles based on the STLA Medium platform will go on sale worldwide and will be available with either front or all-wheel drive. Additionally, a second electric drive module (EDM) at the rear will be available. The BEV output ranges from 160 to 285 kW. Possible body types include passenger cars, crossovers, and SUVs.
