• Stellantis has revealed more details about the STLA Frame platform, which will appear for the first time on the Ram 1500 REV And Ram 1500 Loader which will arrive next year.

• The platform will offer up to 500 miles of range in electric vehicle applications and 690 miles of range in plug-in hybrid range extender configurations.

• Stellantis also said these powertrains will offer a maximum towing capacity of 14,000 pounds and a payload capacity of 2,700 pounds.

In 2023, Ram revealed its future in the form of the 1500 REV electric pickup trucks and the Ramcharger plug-in hybrid pickup trucks. Both trucks are expected to be built on a new platform dubbed STLA Frame, and now Ram’s parent company Stellantis has disclosed more details about the body-on-frame platform that will support both plug-in hybrids fully electric and with range extender. powertrains.

The platform is designed for full-size body-on-frame pickup trucks and SUVs and will be used by the Jeep and Ram brands. With the two previously announced Ram models, we believe the platform could support future iterations of the Jeep. Wagoner And Grand Wagonnier SUV. Vehicle lengths on the STLA Frame platform will range from 216 to 234 inches, with wheelbases between 123.7 and 145.3 inches and vehicle widths between 81.2 and 83.6 inches.

The platform will contain liquid-cooled batteries ranging from 159.0 kWh to over 200.0 kWh, and Stellantis is targeting up to 500 miles of range in purely electric configurations and up to 690 miles with powertrains. with autonomy extension. The EV models will be capable of charging at up to 350 kW using an 800-volt electrical architecture, with the ability to add 100 miles of range in 10 minutes. In range extender configurations, a 400 volt system will result in a maximum charge of 175 kW and an additional range of 50 miles in 10 minutes. STLA Frame will also support bi-directional charging, where vehicles can send power to another electric vehicle, feed it back into the grid, or power a home in an emergency.

In electric vehicle and range extension applications, STLA Frame will feature front and rear electric drive modules that combine the motor, inverter and gearbox into a single package. The engines will be capable of producing up to 335 horsepower each, with a claimed sprint from zero to 60 mph in as little as 4.4 seconds.

For electrified applications, the maximum towing capacity will be 14,000 pounds and the payload will reach 2,700 pounds. Stellantis also claims the platform will allow fording up to 24 inches. STLA Frame will also support the fitting of air suspension and the ground clearance will vary from 6.6 to 10.3 inches depending on the model.

The STLA Frame platform is assembled from high-strength steel which Stellantis says provides high durability and rigidity while minimizing weight. The central section of the platform is widened to accommodate the battery of EV models and the frame rails are reinforced to protect the battery in the event of a side impact. There is also a full-length belly panel that reduces drag to increase range.

In addition to electric vehicle and range-extender configurations, Stellantis says the platform can support pure internal combustion, traditional hybrid, and hydrogen fuel cell powertrains in the future. During a press briefing, Stellantis CEO Carlos Tavares explained that although the company owns a 33% stake in Symbio, a company developing hydrogen fuel cell powertrains, it is still open to partnerships with other automobile manufacturers to reduce the costs linked to the supply of hydrogen. commercialize cell powertrains. However, he reiterated that Stellantis is currently focused on plug-in hybrid electric and range extender powertrains.

The first two models to feature the STLA Frame platform will be the Ram 1500 REV and 1500 Ramcharger. Although the vans were initially expected to go on sale by the end of 2024, Tavares said the trucks would now go on sale in the first half of 2025. The delay, he explained, was because Stellantis “is facing a significant amount of workload” and that the company wants to “be very careful in how we validate products.”

The STLA Frame is one of four new platforms launched by Stellantis as it prepares for an electrified future. The company has already detailed the STLA Large And STLA support platforms. More details on the STLA Small platform are expected in late 2025 or early 2026, Tavares said, although compact vehicles built on this architecture will be geared more toward the European market.
