Karma Automotive has partnered with Factorial to launch the first solid-state battery production program in the United States designed specifically for passenger vehicles. It’s a move that could reshape not just ultra-luxury EVs, but the broader direction of next-generation electric mobility.
At the center of this collaboration is Factorial’s FEST solid-state battery technology, which will be integrated into Karma’s upcoming next-generation vehicle platform. The first model to benefit? The all-electric Karma Kaveya, a jaw-dropping ultra-luxury super-coupé delivering over 1,000 horsepower and a top speed beyond 200 mph, expected to hit U.S. roads in late 2027.
Solid-state batteries are widely seen as the next major evolution beyond today’s lithium-ion cells—and for good reason. Factorial’s FEST technology uses a high-energy solid electrolyte, enabling: longer driving range, improved efficiency, higher performance and greater system stability.
For a high-performance vehicle like the Kaveya, these advantages are critical. Ultra-luxury buyers don’t just want speed—they expect consistency, durability, and cutting-edge tech that actually delivers in the real world.
Built in America, Scaled in America
What makes this partnership especially notable is its fully American foundation.
Karma’s vehicle design, engineering, and manufacturing operations are based entirely in the U.S., while Factorial’s solid-state battery platform is also developed domestically. Together, the two companies are strengthening the U.S. manufacturing ecosystem while accelerating innovation in electric and hybrid vehicle technology.
This isn’t just about one car—it’s about validating solid-state batteries in real production vehicles, not lab prototypes.
No Need to Reinvent the Factory
One of FEST’s biggest advantages is scalability. Unlike many solid-state concepts that require entirely new production lines, Factorial’s technology is designed to work with up to 80% of existing lithium-ion manufacturing equipment.
That means:
– Faster commercialization
– Lower transition costs
– Easier scale-up for mass production
For Karma, this creates a clear and realistic pathway to deploying solid-state batteries without waiting a decade for infrastructure to catch up.
A Delayed Launch, Now with a Clear Vision
Karma originally reintroduced itself to the market with the Kaveya in late 2023, but the company made the bold decision to delay its launch in 2025.
According to Karma CEO Marques McCammon, the reason was simple: the technology wasn’t quite there yet.
With Factorial’s FEST integration, Karma now believes it can deliver the uncompromising driving experience expected from an American ultra-luxury brand—while also laying the foundation for more robust and stable electrified drivetrains in the future.
A Milestone for U.S. EV Leadership
For Factorial, this partnership represents its first U.S. passenger-vehicle production program, marking a major milestone in bringing solid-state batteries out of the lab and onto the road.
High-performance luxury vehicles often serve as proving grounds for new technology—and this collaboration shows exactly how solid-state batteries could scale from halo cars to the wider market.
