JeepRubicon Edition Wrangler
Jan 7, 2002
AUBURN HILLS, Mich., Jan. 7 /PRNewswire/ -- The Rubicon name isn't just
for a Class 10 off-road trail anymore -- it's also what the Jeep brand is
calling their ultimate off-road rig. Jeep owners travel from around the world
to test their four-wheeling skills on the Rubicon Trail in Northern
California, considered one of the most demanding 22 miles of off-highway
driving in America. Jeep engineers have designed the most capable Wrangler
model ever -- and true Jeep owners will realize exactly what that means.
The 2003 Jeep Wrangler Rubicon is engineered to take on the most demanding
trails, even those previously reserved for only highly modified vehicles.
"The 2003 Jeep Wrangler Rubicon features an off-road performance package,
as only Jeep can engineer, allowing serious off-road enthusiasts the
opportunity to drive over some of the most extreme trails in the country, and
then drive it home," said Craig Love, Vice President - Activity Vehicle
Product Team, DaimlerChrysler Corporation.
While its beefy off-road tires and diamond plate sill protectors hint at
the tremendous capability of the Jeep Wrangler Rubicon, it's the underpinnings
that make it worthy of wearing the Rubicon name. On sale in summer 2002, the
Jeep Wrangler Rubicon model features Tru-Lok locking front and rear
differentials, front and rear Dana model 44 axles and the Rock-Trac
4:1 low range transfer case in response to the most demanding off-road
Jeep Engineered Off-Road Package
The new Jeep Wrangler Rubicon has locking differentials that can be driver
actuated when the transfer case is in low range and the vehicle speed is less
than 10 miles per hour. A dash-mounted rocker switch allows the driver to
lock the rear axle and toggle the front axle locker on and off for improved
maneuvering. A pneumatic pump runs at just five pounds per square inch for a
more reliable and quieter system than is available in the aftermarket. This
mechanically locks the axle shafts together to drive all four wheels at the
same speed. When not locked, the rear axle has a torque-sensing limited slip
feature to provide better traction and handling on-road. Dana model 44 axles
with 4.10:1 ratios for both front and rear provide the durability and strength
needed for extreme off-road driving.
"This combination of what would typically be aftermarket hardware provides
tremendous off-road capability to give our enthusiast owners a rig that is
ready for their favorite trails right out of the box," continued Love.
A transfer case with 4:1 low range slows vehicle speed down to give the
driver more control and increases the amount of torque available at the
wheels. This fixed-output NVG241OR transfer case was engineered specifically
for the Jeep Wrangler Rubicon to meet the demanding durability requirements of
an intense off-road vehicle. Also for that reason, this package includes
heavy-duty drive shafts with 1330 universal joints.
Goodyear Wrangler "Maximum Traction/Reinforced" 31-inch tall tires feature
a beefy tread pattern that wraps around the sidewall to help grab ledges along
the trail. This state-of-the-art off-road tire includes a three-ply sidewall
and advanced silica compound for excellent durability and puncture resistance.
The new pattern provides increased tread stiffness and uniform tread wear.
Adding a half-inch of ground clearance over the 30-inch tires, these
LT245/75R16 tires are mounted on new 16-inch, five-spoke aluminum wheels
designed with a dished face to protect the wheel from off-road obstacles.
Standard on Jeep Wrangler Rubicon, four-wheel disc brakes are
self-cleaning off road and provide better brake feel on road, with decreased
stopping distance and reduced brake fade.
Jeep Proven System
The 2003 Jeep Wrangler Rubicon has passed extensive durability and
capability testing created just for this model. Jeep engineers added features
to current test regimens, as well as new tests, to ensure the durability of
this model in severe off-road conditions.
The "K4" durability cycle is a mixture of on- and off-road driving focused
on evaluating body and suspension components. New sections of track were
built for Wrangler Rubicon's version of this test requiring a 4:1 low range
transfer case and axle lockers. Engineers have even recreated a section of
the "Little Sluice" from the famed Rubicon Trail for testing. Development and
validation trips were taken over some of the most challenging trails across
the country. In addition to overall vehicle testing, vigorous bench testing
was conducted on key components such as the axles and transfer case.
Unique Exterior Appearance
The Jeep Wrangler Rubicon features unique exterior design cues and will be
available in Inca Gold as well as the other nine Wrangler exterior colors. A
22-inch long "Rubicon" graphic is prominently placed on each side of the hood.
Heavy gauge diamond plate sill guards are bolted to the body sides to protect
rocker panels from damage in off-road driving.
Rugged Powertrain Choices
The Jeep Wrangler Rubicon features as standard the 4.0-liter PowerTech(TM)
I-6 engine mated to a five-speed manual transmission. Also available with an
automatic transmission, the 4.0-liter engine is rated at 190 horsepower at
4,600 rpm and 235 lb.-ft. of torque at 3,200 rpm.
New Interior Features Complement Rugged Rubicon Exterior
Wrangler Rubicon gets several interior refinements, while still preserving
the true essence of the Jeep brand icon.
