- Stellantis’ STLA Frame platform supports gas, plug-in hybrid, and electric powertrains
- 2025 Ram 1500 REV and 1500 Ramcharger confirmed as first STLA Frame vehicles
- Electrified Jeep Wagoneer SUV based on STLA Frame expected in late 2025
Stellantis on Tuesday confirmed specifications for its STLA Frame modular platform, which the automaker will use for future full-size SUVs, pickup trucks, and light commercial vehicles, including many powered purely by batteries.
The STLA Frame is one of four highly modular platforms to underpin gas, plug-in hybrid, and pure electric vehicles across Stellantis’ diverse range of brands, including here in the U.S. It also supports some hydrogen powertrains, though Stellantis didn’t detail what type.

In addition to the STLA Frame, there’s also the STLA Small, STLA Medium, and STLA Large, and all are designed with commonality and updatability of parts in mind, specifically when it comes to the battery cell chemistry, electric motors, power inverters, and software control. The STLA Large platform will soon be available in U.S. showrooms in the 2024 Dodge Charger.
The STLA Frame is coming soon. It has already been announced for the 2025 Ram 1500 REV electric truck and 2025 Ram 1500 Ramcharger series plug-in hybrid, both of which are due at dealerships shortly. It is also set to go into new electrified Jeep Wagoneer SUVs due from late 2025.

According to Stellantis, the platform is capable of delivering up to 500 miles of range in EVs and up to 690 miles in series plug-in hybrids, essentially EVs with gas engines that serve purely as generators to top up the battery as well as help deliver extra energy to the motors during high-load situations.
Stellantis said owners of vehicles built on the STLA Frame platform can expect up to 14,000 pounds of towing capacity and a payload rating of 2,700 pounds. Those figures are better than what some of Ram’s current light-duty vehicles deliver. Additionally, the platform supports water fording up to 24 inches, making it ready for off-road applications.

The STLA Frame platform, as the name suggests, features a ladder-type frame chassis, albeit with a widened center section to hold a battery for electrified vehicles built on the platform. A full-length belly pan also reduces aerodynamic drag to help maximize driving range. Vehicles based on the platform can range in length from 216-234 inches, feature wheelbases ranging from 123.7-145.3 inches, and sport ground clearances of 6.6-10.3 inches. Stellantis also said tires up to 33 inches in diameter can be fitted.
Battery sizes will initially range from 159 kwh to more than 200 kwh, and thanks to an 800-volt electric architecture, high-speed charging at rates of up to 350 kw will be supported. According to Stellantis, in optimal conditions, as much as 100 miles of range can be added in just 10 minutes of charging. The series plug-in hybrids use a 400-volt system enabling charging at rates of up to 175 kwh. Bi-directional charging capability is also supported.

For electrified vehicles, the STLA Frame platform supports motors at the front and rear axles to form all-wheel-drive systems. The most powerful electric motors generate 335 hp, and Stellantis said some vehicles on the platform will have 0-60 mph times as low as 4.4 seconds.
Stellantis is also expected to introduce vehicles based on the STLA Medium platform in the U.S., though it isn’t clear whether any STLA Small-based vehicles will end up here.
