Stellantis tests solid-state cells in Dodge Charger as battery race intensifies

Stellantis has integrated solid-state battery cells from Factorial Energy into a Dodge Charger Daytona development vehicle and launched a road-testing program to evaluate performance, safety and reliability, according to Design and Development Today. The automaker said the move marks the first integration of solid-state cells into a Stellantis vehicle. The battery uses Factorial's FEST (Factorial Electrolyte System Technology) platform, which the supplier has positioned as a path to higher energy density and faster charging.

The test represents Stellantis' latest push into next-generation battery chemistry as the industry competes to reduce weight and cost while extending driving range. The Turin-based automaker, which produces vehicles across North America and Europe, has positioned solid-state technology as critical to its electrification strategy. The real-world testing program will assess how the cells perform under operational stress—a crucial step before any volume production commitment.
