Karma Automotive and Factorial Announce First U.S. Commercial Solid-State Battery Program for Electric Vehicles
IRVINE, Calif. and BOSTON, Mass., [February 5, 2026] –Karma Automotive Inc (“Karma Automotive), America’s only full-line ultra-luxury automotive manufacturer, and Factorial Inc. (“Factorial”), a U.S.-based leader in solid-state battery technology, today announced the launch of the first solid-state battery production program in the United States for passenger vehicles.
The collaboration will integrate Factorial’s FEST® solid-state battery technology into Karma’s next-generation vehicle platform, beginning with the all-electric Karma Kaveya super-coupe, a high-performance ultra-luxury super car delivering over 1,000 horsepower and top speed in excess of 200mph which is scheduled to arrive on American roads in late 2027.
By pairing Karma’s 100% America-based engineering, vehicle design, and production with Factorial’s U.S.-developed solid-state battery platform, the collaboration strengthens the manufacturing ecosystem and domestic innovation for next-generation electric mobility. Together, the companies aim to accelerate U.S.-led electric and hybrid vehicle technology advancements while validating solid-state technology in a production passenger vehicle environment.
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.
