Responding to Infiniti's challenge of manufacturing a better-performing all-wheel-drive coupling, GKN Driveline will now provide its latest-generation coupling for Infiniti's FX crossover SUV. GKN Driveline had been supplying its coupling technology to the previous generations of the Infiniti FX, and the newest AWD coupling will be smaller and lighter, providing less friction and drag torque.
The AWD coupling is about 30% lighter than previous generations, and provides approximately 80% less drag torque. Integrated into the FX's transfer case, the coupling helps to increase fuel economy with the combination of less weight and increased efficiency with decreased torque drag. The coupling is an Electromagnetic Control Device (EMCD) that controls the driveline's power flow within the AWD system. The EMCD optimizes AWD performance, with up to 50% of the vehicle's power transferrable to the front wheels when needed to maximize traction in necessary driving situations.
Driving situations where power must be balanced between the rear and front wheels include accelerating from a stop, increasing traction and control in turns, and adjusting power for poor, slippery, or unpaved road conditions.
GKN Driveline also has provided its EMCD products for the Nissan Murano crossover and has supplied rear sideshafts for the Infiniti FX50.
