Transmission Technology for Tomorrow’s Industry

Sigma Powertrain’s EMAX Transmissions and MID-Series combine technology and software to provide state of the art power for any class vehicle.

With over 100 combined years of experience in the automotive engineering industry, the core team of engineers, programmers, and technical personnel have over 50 patents in the field of electric powertrains.


EMAX Transmission

Your Single Powertrain Solution

Designed to work with any size or class vehicle.

Extremely high power density. The EMAX is only 18″ long with 4 CVT modes capable of a combined 4600 Nm of input torque. Capacity for a class 8 Semi-Truck yet small enough for a class 1 F150.

Modularity – Common gearbox with interchangeable inputs and outputs.

This is a multi-mode powertrain. Each e-motor operates at 3 and 2 unique ratios respectively, each with independent power flow through a common box thus maximizing system efficiency by keeping more of the drive cycle in the sweet spots for the e-motors.

All Electric powertrain with no hydraulics.

MID-Series Transmission

Multi-Mode Electronic Transmission

Reliable, compact power for your electric vehicle.

Completely integrated 300HP 3-speed BEV to include inverters, heat exchangers, water pump, oil pump and pan. The MID series come complete with integrated powertrain controller, control software, and default calibration.

The MID series is sized for classes 1-6 with a max torque 1370 NM on the output shaft with a top speed of 8000 RPM

The clutches are patented all electric clutches with extreme efficiency and power density.

All versions of the powertrain include electric park and hill hold function
