Nissan Motor Company recently showed off a highly modified Xterra SUV,
called Project X, at the 2001 Gathering of Xterras (GOX 2001) during the
Labor Day Holiday Weekend in Ouray, Colorado. Project X provides an indication
of at least one new technology we expect Nissan to offer on its upcoming
2004 full-size and Frontier compact pickups - electronic locking front
and rear differentials.
differential solution demonstrated on Project X was developed in cooperation
with Eaton and its Torque Control Products Division. Known as ELocker,
the system is activated manually using switches on the truck's dash -
one for each axle.
allows your truck's wheels to spin at different rates through turns but
can be a handicap during some off-road conditions when a spinning wheel
can't get enough traction. Locking differentials prevent the wheel with
the least amount of traction from spinning and transfer up to 100% of
the spinning wheel's torque to the wheel with a better grip so you don't
get stuck in the sand, mud or snow.
locking differentials are activated either automatically or manually.
The ELocker's differential can be activated at any moment by the
driver to provide additional traction on demand in hairy off-road situations
and turned off just as quickly.
Toyota offers an electronically activated locking rear differential as
an option on their pickups.
trucks are available with optional front and rear automatic locking differentials.
Automatic locking diffs are typically activated when a slipping wheel
reaches a certain RPM and require no driver intervention.
clearly stated that it expects to set new standards with its 2004 full
size pickup and this will most likely be one of the innovations that will
