Stellantis has announced plans to launch a demonstration fleet of new Dodge Charger Daytona vehicles equipped with Factorial’s solid-state in 2026. In rolling out this fleet, both companies are looking to enable both the validation of Factorial’s technology and assess its performance in real-world driving conditions.
The fleet will launch as part of an expanded partnership between the companies, through which they are more broadly aiming to develop and deploy next-gen EVs powered by Factorial’s solid-state battery technology. This initiative builds upon the $75 million investment Stellantis made in Factorial in 2021.
Factorial will supply Stellantis with cells based on its proprietary FEST solid-state battery technology, which enables a specific energy density exceeding 390 Wh/kg. Factorial has said that FEST offers higher energy density, reduced weight, improved performance and a potential for further reduction in total vehicle cost over time when compared to traditional lithium batteries. Through these qualities, the company believes FEST to be an ideal candidate for powering next-generation EVs.
These solid-state batteries will then be fitted into STLA Large, Stellantis’ multi-energy EV platform. STLA Large was chosen based on its ability to form the base of high-volume electric SUVs and performance vehicles. For Stellantis, this platform represents a key element of its Dare Forward 2030 strategic plan and is being utilized across its brand portfolio in vehicles by Jeep, Dodge, Chrysler, Alfa Romeo, and Maserati.
