Stellantis N.V. announced plans to launch a demonstration fleet of Dodge Charger Daytona vehicles equipped with solid-state batteries by 2026, marking a significant advancement in its partnership with battery maker Factorial Inc.
The initiative expands on Stellantis’ $75 million investment in Factorial made in 2021. The automaker will use Factorial’s FEST solid-state battery technology, which delivers an energy density exceeding 390 Wh/kg. The technology promises higher energy density, lighter weight, and improved performance compared to conventional lithium-ion batteries.
The demonstration vehicles will be built on Stellantis’ STLA Large platform, designed for electric SUVs and performance vehicles across brands including Jeep, Dodge, Chrysler, Alfa Romeo, and Maserati. The platform is expected to support production of up to two million vehicles globally.
“This demonstration fleet is an important milestone in our partnership with Factorial,” said Ned Curic, Stellantis’ Chief Engineering and Technology Officer. “By integrating Factorial’s innovative battery solution into the STLA Large platform, we are validating its potential to enhance our electric vehicle lineup, ensuring customers benefit from improved performance, longer driving ranges and faster charging times in the coming years.”
Factorial CEO and Co-Founder Siyu Huang said, “We are honored to be part of this journey with Stellantis to accelerate the adoption of electric vehicles. We believe solid-state technology can play a crucial role in enabling the next generation of EVs with improved performance and reduced costs.”
The real-world testing program will evaluate the performance of Factorial’s solid-state technology under actual driving conditions. The partnership aligns with Stellantis’ Dare Forward 2030 strategic plan, which emphasizes the company’s transition to electric vehicles.
