The helical -
bevel gear motor reduces energy loss by up to 40 %, while a variable speed AC
drive provides soft - starting to reduce product breakage.
However, an extra shaft from this differential also
drives a
bevel gear housed in the transfer case that permanently turns a driveshaft for the rear wheels (i.e. there is no longer a «center» differential).
Designed with a classic
bevel gear layout, it sent 50 percent of the torque to the rear axle via the prop shaft in every
driving situation.

However, as the development process continued, engineers at BorgWarner discovered that, with clever software programming, they could control the variable electromagnetic multi-disc clutch to a point where it would allow the front and rear
drive shafts to turn at different rotational speeds on its own, without the aid of a planetary or
bevel geared center differential.
Unlike the process used by the existing Torsen torque sensing quattro system, the only rear - wheel
drive components engaged when running in front wheel
drive are the
bevel gears within the axle and
gears within the differential — the latter of which compensate for differences in the speed of rotation of the wheels during cornering.
Only the axle
bevel gear and the compensating
gears in the differential, which compensate for differences in the speed of rotation of the vehicle's
drive wheels during cornering, continue to rotate under zero load.
