REDDITCH, England, Sept. 3, 2013 /PRNewswire/ --The new 2014 Range Rover
Evoque has a unique "disconnect" all-wheel-drive system developed by GKN
Driveline. The system is designed to improve fuel efficiency while providing
outstanding off-road performance with dynamic agility and enhanced traction.

Land Rover's Active Driveline system reacts to the driving environment and
driver intention by automatically disconnecting the major rotating driveline
components to reduce energy losses. Traction and driving stability are
optimized by an Active Torque Biasing feature that offers advanced control on
the distribution of torque between the front and rear wheels.

The Active Driveline system demonstrates the benefits of partnering with GKN
Driveline on whole driveline supply and integration. The co-development of
Land Rover's Active Driveline has achieved a significant reduction in
driveline spin loss, which in turn contributes to the 2014 Range Rover
Evoque's overall fuel-consumption reduction of up to 11.4 percent (depending
on model).

The GKN all-wheel-drive system includes a GKN power transfer unit (PTU),
linked to the transmission's final drive differential, containing a
synchronizer and brake to disconnect the all-wheel-drive system upstream of
the PTU hypoid gears.

At the rear of the system the GKN TWINSTER^® rear drive module (RDM) drives
each rear wheel via an independent wet multi-plate clutch that can disconnect
the all-wheel-drive system downstream of the RDM hypoid gears.

The GKN PTU synchronizer and GKN TWINSTER^® are controlled by a dedicated
driveline control unit designed to constantly monitor vehicle dynamics,
disconnecting during steady-state driving speeds above 22 mph and
automatically reconnecting (within 300 milliseconds) when required.

In addition to the disconnect function, the GKN TWINSTER^® also acts as an
electronic differential combining drive vectoring and limited-slip
differential technology for active torque biasing.

"We are delighted to have worked with Land Rover to develop and supply this
advanced GKN all-wheel-drive system incorporating our TWINSTER^® rear-drive
module," said Rob Rickell, GKN Driveline's global engineering director. "The
step change in vehicle efficiency and dynamic performance sets a new industry
benchmark for this type of vehicle."

In addition to the innovative Active Driveline, GKN Driveline also supplies
the all-wheel-drive system for the 2014 Range Rover Evoque's Standard
Driveline. Power transfer units and rear-drive modules for both variants are
produced at GKN Driveline Koping in Sweden with front sideshafts and
propshafts supplied out of GKN Driveline Birmingham, UK.
