Stellantis has  unveiled their all-new multi-energy STLA Frame platform, a modular foundation for internal-combustion, hybrid and all-electric vehicles.

The STLA Frame has joined the previously announced STLA Medium and STLA Large platforms. The STLA Frame, to be utilized first by Jeep and Ram vehicles like the upcoming all-electric Ram 1500 REV, will provide a versatile body-on-frame basis for gasoline, hybrid, hydrogen, and battery-electric solutions, the latter also including range extender electric vehicle (REEV) tech, such as that previously announced on the Ram 1500 Ramcharger.

On this platform, BEVs will see up to 500 miles of range on a full charge, while REEVs are estimated up to 690 miles (for those unclear on the concept, range extended EVs utilize an onboard, internal-combustion generator that recharges the battery). Underpinning full-size pickups, SUVs and commercial vehicles, the STLA Frame features standard all-wheel drive with dual electric drive modules (EDMs). It’s capable of hosting 800-volt EV architecture, recouping 100 miles of range in 10 minutes when being juiced up by a 350 kW DC fast charger; bidirectional charging (using stored energy to charge other vehicles, for example) is also supported.

Those EDMs are rated up to 250 kW each, capable of 0-60 mph sprints of 4.4 seconds. The platform can accommodate different suspension setups, including air suspensions; and as for towing, Stellantis provided a max towing figure of 14,000 lbs, joined by a payload rating of 2,700 lbs. 

The STLA Frame can support vehicles between 216-234 inches long, with wheelbases between 123.7-145.3 inches. At these sizes, the ability to support adequate battery packs is, of course, a necessity, and this foundation is designed to support liquid-cooled packs as small as 159 kilowatt-hours and packs larger than 200 kilowatt-hours. Its high-strength steel composition is said to have improved durability and rigidity with less weight. The center section has been widened to accommodate the battery pack, and the frame rails have been bolstered to better protect said battery during side impact collisions. The whole thing is underscored by a full-length belly pan, improving aerodynamics.

Stellantis is investing heavily into their goals of 50% passenger car and light-duty truck BEV sales in the U.S. by 2030, and 100% passenger car BEV sales mix in Europe.
