Stellantis previews 4 electric platforms: Here’s how they’ll be used


Stellantis EV Day is hitting hard and fast this morning, with big news coming from Dodge and Ram and Jeep and the rest. But to support those brand transformations, a core initiative within Stellantis will help it become a leader in electrification. To do that, the group is developing platforms and technologies with cross-shared components and systems.

This starts with four flexible BEV platforms: STLA Small, STLA Medium, STLA Large and STLA Frame. As for targeted numbers, they’re lofty: By 2024, Stellantis aims for over 500 miles of range, 0-62 mph in 2 seconds and charging 200 miles of range in 10 minutes.

The four platforms will offer battery capacities from 37 kWh to more than 200 kWh. More specifically, STLA Small will offer 37-82 kWh and up to 300 miles of range. STLA Medium will have 87-104 kWh and up to 440 miles. STLA Large will provide 101-118 kWh and up to 500 miles of range. The truck-focused STLA Frame will provide 159-200+ kWh and up to 500 miles of range (and will support an electric Ram 1500 pickup).


Stellantis has big plans for the STLA Large platform, and is currently developing eight vehicles for it in the next three to five years. Examples of possible vehicles shown include a midsize Ram truck and a Jeep off-roader that could fight against the likes of the Toyota 4Runner. Stellantis design boss Ralph Gilles could be seen in a presentation looking over a Chrysler electric crossover based on this platform. We also saw a Wagoneer badge teased momentarily. There was a rendered silhouette of a crossover that looked like it could compete with the Ford Mustang Mach-E. Gilles said the platform would allow Stellantis to “create a long-range luxury sedan, an all-conquering muscle car, a heart-of-the-market DUV, a heart-of-the-market SUV, a very capable Jeep off-roading white-space opportunity vehicle as well as a new mid-sized truck.” See for yourself in this video starting at the 59-minute mark.

As for powertrains, Stellantis is developing three electric drive modules with a shared, scalable inverter, and other common components, as well as in-house software to control them. Those drive units will offer from 70 to 330 kW (94-402 horsepower). More specifically, one EDM will provide 70 kW, a second will provide 125-180 kW, while the most potent can produce 150-330 kW. Let us imagine, for a moment, an all-wheel-drive Dodge muscle car with two of those 330-kW drive units …


Finally, batteries are another core ingredient to the successful EV formula. Stellantis is pursuing a multi-pronged strategy on battery chemistries. One is NiCo-free (that is, free of nickel and cobalt), another other is nickel-based. Additionally, Stellantis plans to develop a solid-state battery by 2026. The bottom line is Stellantis believes it can lead the industry in cost per kilowatt hour, while providing flexibility to adapt to different needs for different body styles, different brands and different markets.
