Karma Automotive, the only U.S. manufacturer offering a full lineup of ultra-luxury vehicles, has partnered with Factorial Energy, a U.S.-based leader in solid-state battery technology, to launch the nation’s first solid-state battery production program for passenger cars.
As part of the collaboration, Factorial’s FEST solid-state battery technology will be incorporated into Karma’s next-generation vehicle architecture, starting with the all-electric Karma Kaveya super-coupe. This ultra-luxury, high-performance vehicle is expected to deliver more than 1,000 horsepower, exceed 200 mph in top speed, and enter the U.S. market in late 2027.
Combining Karma’s fully U.S.-based engineering, design, and manufacturing capabilities with Factorial’s domestically developed battery platform, the partnership strengthens America’s electric vehicle manufacturing ecosystem. Together, the companies aim to advance U.S.-led electric and hybrid vehicle innovation while proving solid-state batteries in real-world production vehicles.
Factorial’s FEST solid-state battery technology enables higher performance through a high-energy electrolyte system designed to support extended driving range and enhanced overall vehicle efficiency compared to conventional lithium-ion batteries. These attributes make FEST particularly well-suited for the performance and design requirements of the Karma Kaveya.
“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.
FEST technology is engineered to integrate into today’s lithium-ion battery factories. Rather than relying on entirely new production lines, Factorial’s FEST cells work with up to 80 percent of existing lithium-ion manufacturing equipment. This compatibility enables rapid scale-up of Factorial’s commercial production program with Karma Automotive.
“Launching our first U.S. passenger-vehicle program with Karma is a meaningful milestone for Factorial,” said Siyu Huang, CEO of Factorial. “FEST was built to scale, and this milestone not only highlights the energy and performance solid-state technology can deliver but also underscores the global leadership of U.S. technology innovators. High-performance luxury vehicles require cutting-edge innovation, and this collaboration showcases what’s possible when performance leads.”
This partnership brings Factorial’s American solid-state battery cell technology into a U.S.-designed, engineered, and manufactured ultra-luxury automotive architecture, pioneering a new path that accelerates the transition to next-generation battery technology at scale in a way that is innately American.
