Karma Automotive and Factorial have jointly unveiled what they describe as the first solid-state battery production program in the United States aimed at passenger vehicles, marking a significant push in domestic electric vehicle (EV) innovation. The collaboration pairs Karma, known as America’s only full-line ultra-luxury automotive manufacturer, with U.S.-based solid-state battery specialist Factorial to integrate next-generation battery technology into future EVs.
Under the new arrangement, Factorial’s FEST solid-state battery technology will be incorporated into Karma’s next-generation vehicle architecture, beginning with the all-electric Karma Kaveya super-coupe. The luxury EV is positioned as a high-performance model, boasting more than 1,000 horsepower and a top speed exceeding 200 mph, and is scheduled to hit roads in late 2027.
The partners say the initiative not only seeks to elevate vehicle performance but also to fortify U.S.-based manufacturing and technology leadership in the EV sector. Karma brings 100 % American engineering, design and production to the project, while Factorial contributes its domestically developed battery technology designed to enhance energy performance and efficiency compared with traditional lithium-ion systems.
Central to Factorial’s approach is the FEST battery system’s compatibility with existing lithium-ion production infrastructure, designed to work with up to about 80 % of current battery manufacturing equipment. This compatibility is expected to accelerate commercial scaling of solid-state battery production alongside Karma’s vehicle rollout.
Karma’s leadership described the partnership as a key milestone in delivering an uncompromised ultra-luxury driving experience. According to company executives, technical hurdles that previously delayed the Kaveya’s launch have been addressed through the integration of advanced battery systems, paving the way for more stable and powerful electrified drivetrains in future Karma vehicles.
Factorial’s CEO also highlighted the broader implications of the deal for U.S. clean-technology innovation, noting that the collaboration reinforces American leadership in advanced battery development. The companies say their work together will help validate solid-state technology in real-world passenger EVs and support the broader transition to cutting-edge electric and hybrid mobility solutions.
