Drive farther and smarter with Magna eDecoupling 

Magna eDecoupling is a stand-alone device that helps electric vehicles go longer distances by reducing drag torque. It also improves safety and makes driving easier. First-to-market and launched for German premium OEM in 2023.  

 

  • Increase driving range by up to 9% with reduced drag torque in e-motors and gearboxes
  • Compact packaging for seamless integration and minimal added weight in EVs
  • Rapid activation times and superior NVH characteristics for optimal performance and smooth ride
  • Enhanced safety with improved energy efficiency, traction, and stability

How it works:

eDecoupling reduces drag-losses in vehicles by disconnecting the differential, gearbox, and e-motor from the wheel axle when propulsion power is not needed. This helps improve the range of electric and hybrid vehicles by up to 9% by reducing the energy draw from the battery, especially in AWD and 4WD vehicles and BEV or hybrids with secondary axles. 

How it supports 2WD and 4WD driving:

It can seamlessly switch from 2WD to 4WD when road conditions are unstable. Magna's eDecoupling, along with the predictive software package "Decoupling+", enhances vehicle performance by reducing slip and vehicle yaw on high-speed corners under slippery road conditions. By utilizing vehicle sensory inputs, it automatically engages 4WD power before the vehicle starts to slip.

First-to-market innovation 

eDecoupling Family 

 

The new and innovative modular eDecoupling unit aligns perfectly with OEMs’ in-house manufacturing strategies for electric drive systems:  

  • Modular eDecoupling unit 
  • Fast activation time of less than 100 milliseconds
  • Compact size minimizes weight and package space in both axial and radial directions
  • Scalable for use across electric and hybrid vehicles from B segment up to SUVs and LCVs.
