The flexible platform can accommodate AWD, FWD, and RWD configurations as well as electric, hybrid, and internal-combustion powertrains.
Along with providing up to an estimated 500 miles of range, EV versions of STLA Large are claimed to deliver a zero-to-62-mph time of about 2.0 seconds.
Stellantis—the parent company of familiar brands like Chrysler, Dodge, Jeep, and Ram—today divulged details about its new STLA Large platform. The company said the flexible architecture is expected to underpin upcoming models from Dodge and Jeep that will launch later this year.
That implies the electric 2025 Jeep Wagoneer S, which yesterday was confirmed to be arriving in the U.S. this fall. Last week, Dodge released several teaser images of the 2025 Charger on its social media channels, mentioning that it'll be "available late 2024."
The timing of those announcements likely isn't coincidental, and that's why today's news about the STLA-L platform provides more details about both the new Charger and Wagoneer S as well as six other unspecified vehicles that will launch globally sometime during the next coupe of years. New models from Alfa Romeo, Maserati, and Chrysler will be the first of that bunch.
STLA Large Details
While STLA Large is an EV-centric platform that's available with either a 400- or 800-volt architecture, Stellantis says it can also accommodate hybrid and internal-combustion powertrains. That corroborates online reports that the new Dodge Charger will be offered not only as an EV, but also with a gas-fed engine—likely a version of the Hurricane twin-turbo 3.0-liter straight-six that's currently capable of producing over 500 horsepower.
STLA-L also supports transverse and longitudinal engines layouts and limited-slip differentials. Notably, Stellantis points out that the platform can handle "extreme power that will outperform any of the existing Hellcat V-8s." Considering the most powerful Hellcat engine (found in the Dodge Challenger SRT Demon 170) makes up to 1025 horsepower, we believe that's likely the bogey for the highest-performance version of the new Charger EV.
Thanks to its flexible nature, the STLA Large platform offers three different drivetrain configurations, including all-wheel drive, front-wheel drive, and rear-wheel drive. Its wheelbase can be stretched from 113.0 to 121.0 inches. Stellantis says overall lengths range between 187.6 and 201.8 inches; overall widths range from 74.7 to 79.9 inches. The platform's lowest ground clearance is 5.5 inches and the highest is 11.3 inches. For off-road-oriented models like the Jeep, Stellantis says the largest tire diameter that will fit is 32.6 inches.
STLA-L EV Details
Other details from today's announcement provide new details about the upcoming EV models that will use the STLA Large platform. Their battery capacities are said to range from 85.0 to 118.0 kWh, however, it's unclear whether that's their net or gross capacity (we suspect the latter). Stellantis says its targeting a 500-mile driving range for electric sedans with the 800-volt architecture. Although that estimate is likely based on the more optimistic European WLTP test cycle, suggesting an EPA equivalent of about 425 miles, which is still impressive.
Regarding the electric drive modules that incorporate the gear reduction, motor, and power inverter, Stellantis says it will use silicon carbide for the semiconductor material, which is intended to minimize losses compared with traditional silicon material. Porsche is doing the same with its PPE platform that will underpin the Macan EV. Stellantis also said that over-the-air updates will allow the powertrains' performance to be upgraded during the course of the vehicles' life. STLA-L will support the company's next-gen technologies, including STLA Brain, STLA SmartCockpit, and STLA AutoDrive.
Stellantis' other platforms include the STLA Small, Medium, and Frame designations. The latter will underpin the forthcoming electric Ram 1500 REV and Ram 1500 Ramcharger plug-in hybrid pickup trucks. We believe the first Chrysler EV (possibly based on the AirFlow concept) will use the STLA-M platform.
