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.
