Stellantis’ electric STLA Frame gives vehicles 690 miles of range with an extender

STLA Frame supports bidirectional charging, and its pure EV version has an 800-volt architecture with up to 350kW of DC fast charging speeds that can add 100 miles in 10 minutes. When configured with a gas range extender (REEV), the platform uses a 400-volt architecture with up to 175kW charging that adds 50 miles in 10 minutes.

STLA Frame will give trucks like the Ram 1500 Ramcharger up to 690 miles of range with the help of a gas-powered range extender, or 500 miles purely on battery for the Ram 1500 REV. The platform can also handle 14,000 pounds of towing capacity and can hold a 2,700-pound payload.

The STLA Frame platform is designed for big vehicles like full-sized pickup trucks, SUVs, and commercial vehicles. Stellantis plans to use it for big Jeep SUVs and Ram trucks, including the Ram 1500 Rev, which is now being delayed from the end of 2024 to the first half of 2025. Meanwhile, the company’s STLA Large platform will underpin upcoming EVs like the Jeep Wagoneer S and Dodge Charger Daytona.

There’s also an STLA Medium for some European vehicles and will likely underpin an upcoming smaller Jeep vehicle in the US. The automaker also has a fourth STLA Small platform intended for Fiats and Peugeots, but it hasn’t been fully fleshed out yet.

The new platform is being announced at a critical time for the automaker. American dealers have accused Stellantis of not releasing affordable vehicles and degrading the brands. The company had cut its profit forecast for the year and had a leadership shakeup last month.
