First US solid-state EV battery to power 1,000+ hp Karma electric car

Factorial Energy has launched its first commercial solid-state battery program in the US, partnering with Karma Automotive to integrate its FEST (Factorial Electrolyte System Technology) batteries into Karma’s ultra-luxury electric vehicles. The collaboration will debut with the Karma Kaveya, an all-electric super-coupe boasting over 1,000 horsepower, 1,270 lb-ft of torque, a range exceeding 250 miles, and a 0-60 mph time under 3 seconds. Scheduled for a late 2027 US launch, this program aims to validate solid-state battery technology in real-world passenger vehicles while advancing domestic EV battery innovation. The FEST batteries offer significant advantages, including 500 to 600+ miles of range, approximately 40% weight reduction compared to traditional lithium-ion cells, and compatibility with up to 80% of existing lithium-ion manufacturing equipment. This compatibility facilitates faster scaling and production without the need for entirely new manufacturing lines. Karma’s president emphasized that the partnership enables delivering
