EMAX Transmission
Your Single Powertrain Solution
Designed to work with any size or class vehicle.
One size fits all
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.
Multiple motor inputs to meet any power needs
Modularity – Common gearbox with interchangeable inputs and outputs.
Multi-mode maximizes electric efficiency
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.
No hydraulics
All Electric powertrain with no hydraulics.

MID-Series Transmission
Multi-Mode Electronic Transmission
Reliable, compact power for your electric vehicle.
Completely integrated
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.
Sized for classes 1-6
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
