Sigma Powertrain makes the world's most advanced electric powertrains. Our flagship product is the EMAX.

The EMAX is a multi-ratio gearbox. Multiple ratios allow for greater efficiency and a better driving experience.

It can accept up to 4600 NM of torque in just an 18″ package, providing power and flexibility in placement.

As a modular powertrain, the motors, extension housings, and output shafts can all be changed without having to change the transmission.

Our MID series, while also modular, is a plug and play powertrain. 

Our products are on display and a demo drive is available.
