GKN’s all-wheel-drive rolls out in China

GKN Driveline’s Chinese Joint Venture is bearing fruits. Its partner SDS has commenced production of the complete all-wheel drive (AWD) Disconnect system for small to medium-sized vehicles in China.
The system will initially feature on the Jeep Renegade built for the Chinese market by GAC Fiat Chrysler Automobiles Co., Ltd. (GAC FCA) in Guangzhou City, southern Guangdong Province.
GKN’s Chinese joint venture, Shanghai GKN HUAYU Driveline Systems (SDS), will supply GAC FCA from its production facility in Shanghai. GKN manufactures the complete all-wheel drive system, including the power transfer unit (PTU), rear drive module (RDM), prop-shaft and side-shafts, as well as supplying software controls.
The move marks another milestone in the growth of GKNs AWD business in China. SDS successfully localised production of PTUs and RDMs for JaguarLandRover models in 2015, including the Range Rover Evoque and Land Rover Discovery Sport, as well as localising production for two further automakers last year. SDS is no doubnt pleased to have access to UK technology – something it could not have developed itself at such a fast rate and as a result more localisation programmes are due for SOP (start of production) over the next two years for a range of manufacturers.
SDS added six new AWD assembly lines and a new hypoid gear production line across two of its facilities in Shanghai during the past 18 months, as well as testing and other equipment, to support growing levels of business. The investment significantly expanded the companys AWD production capacity in China.
Phil Swash, chief executive officer, GKN Driveline, said: GKN has capabilities to manufacture sophisticated all-wheel drive systems on a global basis and thats why automakers choose to partner with us on their mega-platforms. The demand for all-wheel drive vehicles is growing at a rapid rate in China and GKN and SDS have a number of localisation and domestic programmes in the pipeline for the coming years.
GKN’s scalable AWD Disconnect system was first launched on the Jeep Renegade and Fiat 500X subcompact crossover SUVs. As well as China, GKN builds the system at facilities in Europe and North America, and supplies the system in India and South America.
The Disconnect function enables vehicles to combine enhanced traction, dynamics and stability of all-wheel drive with improved on-highway fuel efficiency. The system reacts to driver inputs and road conditions, allowing it to switch seamlessly between two-wheel drive and all-wheel drive.
During steady state cruising, the clutch system disengages the rear section of the driveline, eliminating rotating losses and improves highway fuel economy by up to 4% compared to standard AWD. If the driver or conditions require more traction, the system reconnects within 300 ms.
