Kinetic Drive, LLC is a Cleburne, Texas company developing a mechanical flywheel drivetrain that sits between a vehicle's engine and its drive wheels, spinning up on braking and feeding torque back to the axle on acceleration. The company states the system recovers about 95% of braking energy, stores 412 kJ at 28,400 RPM, and drops into existing vehicle platforms without batteries or charging infrastructure. It is led by inventor Raymond (Ray) Sherry, who holds a 2016 US patent on a flywheel-operated vehicle using a differential axle and completed a proof-of-concept vehicle in July 2023. The company's published roadmap lists a SEMA debut in 2025, a C/K1500 production launch and fleet pilots in 2026, and OEM licensing from 2027.
