Dodge Charger Daytona To Debut Solid-State Batteries In 2026
Stellantis is helping advance solid-state battery technology, with plans to incorporate the technology into a demonstration fleet of Dodge Charger Daytonas by 2026.
Partnering with Massachusetts-based Factorial Energy, Stellantis will use Factorial’s Electrolyte System Technology (FEST) to enhance EV performance, pushing potential ranges beyond 600 miles per charge. This would substantially improve on the current offer from lithium-ion batteries, which typically deliver around 300 miles of range.
Solid-state batteries differ from conventional lithium-ion batteries by utilizing a solid electrolyte instead of a liquid one, which increases energy density, reduces weight, and improves overall efficiency. If successful, this breakthrough could reduce charging times and offer longer driving ranges, addressing range anxiety—a major concern among potential EV buyers. The partnership between Stellantis and Factorial began in 2021 with a $75 million investment from the automaker.
The 2026 Dodge Charger Daytona models will be built on Stellantis’ STLA Large platform, a versatile architecture designed for electric and hybrid vehicles. Testing in real-world conditions will help validate solid-state battery capabilities and their potential to revolutionize electric mobility. If successful the program could evolve to include other STLA Large-based vehicles from Jeep, Alfa Romeo, Maserati, an Chrysler.
Despite the promise, experts believe that widespread adoption of solid-state batteries could still be years away due to production challenges. Factorial is working to scale up manufacturing, but significant hurdles remain before the technology can be applied at an industry-wide level.
