Karma Automotive and Factorial have launched the first solid-state battery production program in the United States aimed at passenger vehicles. The collaboration will integrate Factorial’s FEST® solid-state technology into Karma’s next-generation electric vehicle platform, starting with the all-electric Karma Kaveya super-coupe. The Kaveya is designed to deliver more than 1,000 horsepower and exceed 200 mph, with market introduction expected in late 2027.
By combining Karma’s fully American–based engineering, design, and manufacturing capabilities with Factorial’s U.S.-developed solid-state platform, the partners intend to reinforce domestic innovation in electric mobility. The program will validate FEST® technology in a production environment, advancing both electric and hybrid vehicle systems in the U.S. market.
Factorial’s FEST® cells use a high-energy electrolyte system that supports extended driving range and improved overall efficiency compared to traditional lithium-ion batteries. The design also allows up to 80 percent of existing lithium-ion production equipment to be reused, facilitating a faster scale-up of commercial manufacturing without the need for entirely new production lines.
“Karma Automotive was imagined to push the boundaries of what the ultra-luxury vehicle experience can be, and Kaveya is the vehicle that re-introduced Karma to the market in November 2023,” said Marques McCammon, President and Chief Executive, Karma Automotive.
“However, in 2025 we delayed launch because we did not yet see a clear path to fully delivering the uncompromising driving experience that should be expected from an American ultra-luxury vehicle company. Now through the partnership with Factorial and the integration of FEST®, we cannot only deliver that experience, but also open a pathway to stronger, more stable electrified drive systems for Karma owners and the broader industry,” concludes McCammon.
Siyu Huang, CEO of Factorial, described the program as a significant milestone for the company. “FEST® was designed for scalability and performance. This collaboration not only demonstrates the potential of solid-state technology in high-performance luxury vehicles but also highlights the strength of U.S. technology leadership,” Huang noted.
This partnership brings together American solid-state battery innovation and ultra-luxury vehicle engineering, aiming to accelerate the adoption of next-generation battery systems at scale.
