Ram has unveiled its plan for the future with the introduction of the electric 1500 REV and the plug-in-hybrid Ramcharger pickup trucks in 2023. These trucks will be built on the new STLA Frame platform, and Stellantis, the parent company of Ram, has shared more details about this body-on-frame platform that will support both fully electric and range-extender plug-in hybrid powertrains.
The STLA Frame platform is specifically designed for full-size body-on-frame pickup trucks and SUVs, and it will be utilized by both the Jeep and Ram brands. In addition to the Ram models, this platform could potentially be used for future versions of Jeep’s Wagoneer and Grand Wagoneer SUVs as well. The vehicles built on this platform will vary in length from 216 to 234 inches, with wheelbases ranging from 123.7 to 145.3 inches and vehicle widths between 81.2 and 83.6 inches.
In terms of electric-vehicle applications, the STLA Frame platform will accommodate liquid-cooled battery packs with capacities ranging from 159.0 kWh to over 200.0 kWh. Stellantis is aiming for up to 500 miles of range in fully electric setups and up to 690 miles in range-extender configurations. The platform will support fast charging with the ability to add 100 miles of range in just 10 minutes for EV models.
For range-extender setups, a 400-volt system will allow for peak charging of 175 kW and the addition of 50 miles of range in 10 minutes. The bi-directional charging feature of the STLA Frame platform will enable the vehicles to transfer energy to other EVs, back to the grid, or even power a home during emergencies.
The platform will feature front and rear electric drive modules that combine the motor, power inverter, and gear reducer into a single package. Each motor can produce up to 335 horsepower, enabling the vehicles to accelerate from zero to 60 mph in as little as 4.4 seconds. The maximum towing capacity for electrified applications will be 14,000 pounds, with a payload rating of up to 2700 pounds. Additionally, the platform will allow for water fording of up to 24 inches and can support air suspension for varying ground clearance between 6.6 and 10.3 inches depending on the model.
Constructed from high-strength steel, the STLA Frame platform provides durability and rigidity while minimizing weight. The widened center section of the platform accommodates the battery pack for EV models, and the reinforced frame rails offer protection for the battery in case of a side impact. Furthermore, a full-length belly pan reduces drag to enhance driving range.
Apart from EV and range-extender setups, Stellantis has noted that the platform has the potential to support other powertrains in the future, including pure internal-combustion, traditional hybrid, and hydrogen fuel-cell options. While Stellantis has a stake in a company developing hydrogen fuel-cell powertrains, the company remains open to partnerships to reduce costs for bringing such technologies to market. However, the current focus is on electric and range-extender plug-in-hybrid powertrains.
The STLA Frame platform is part of Stellantis’ strategy to embrace an electrified future, with plans to launch four new platforms. While the STLA Frame is geared towards full-size vehicles, the company has also introduced the STLA Large and STLA Medium platforms. Details about the STLA Small platform are expected to be revealed in the coming years, with a focus on compact vehicles more suited for the European market.
