BorgWarner is supplying its
GenV all-wheel drive (AWD) coupling for the BMW Group’s all-new 2 Series Active
Tourer. The electro-hydraulically actuated AWD coupling automatically
distributes power between the front and rear wheels of BMW brand’s first-ever
front-wheel drive vehicle. Apart from optimising traction and vehicle dynamics
under almost all conditions, the GenV AWD technology enhances the vehicle’s
driveline efficiency and features an Efficient Mode for reduced driveline
losses.
BorgWarner’s advanced AWD
technology is available in the BMW 220d xDrive Active Tourer as well as in the
BMW 225i xDrive Active Tourer since November 2014, helping both models set new
benchmarks in efficiency and dynamic performance.
“We are proud to expand our
successful relationship with the BMW Group and provide improved traction,
stability and handling for their first front-wheel drive vehicle with our
latest AWD technology,” said Dr. Stefan Demmerle, President and General
Manager, BorgWarner TorqTransfer Systems, adding that “Our GenV coupling
features market-leading advanced electronic controls to meet automakers’
customized requirements in terms of driving behavior and fun-to-drive
characteristics.”
BorgWarner adapted the GenV
integrated electronic control module to match BMW’s unique driving characteristics
and its demanding specifications for improved traction and handling. The
advanced software calculates and delivers pre-emptive as well as immediate
response with high-torque accuracy based on data supplied by the on-board
electronics to provide exceptional dynamic performance. Without any driver
input, the electronically controlled multi-plate clutch distributes power
between the front and rear axles automatically. In addition, the GenV AWD
coupling improves fuel economy by providing only the requested amount of torque
to the rear axle, optimised for nearly all driving situations. If necessary,
full locking torque is available at any given time and speed, depending on road
conditions and vehicle load distribution.
For the first time,
BorgWarner’s GenV coupling is equipped with the Efficient Mode functionality
featuring an intelligent valve that manages the clutch lubrication to
significantly reduce losses. In this mode, the coupling provides better fuel
economy when AWD function is not needed. BorgWarner’s AWD coupling features a
lightweight and compact design for reduced vehicle complexity and simplified
integration into the powertrain. As a result, the GenV delivers improved
traction as well as extremely agile, precise and stable handling.
