Integrated powertrain systems built around advanced gearbox technology.

Sigma Powertrain delivers complete propulsion solutions for light-, medium-, and heavy-duty commercial vehicles. Our proprietary gearbox platforms form the foundation of systems engineered for torque control, efficiency, durability, and drivability.

We design and integrate the full powertrain architecture, including motor pairing, controls, cooling, and calibration. The result is optimized performance and long-term reliability across on-road and off-road applications from last mile delivery and long haul to ports logistics.
