    What is it?
    2003 Jeep Wrangler Rubicon

    What's special about it?
    All production Jeeps must be able to survive a trip down California's Rubicon Trail, 22 miles of some of the hairiest off-roading available in North America. For 2003, Jeep creates the Wrangler Rubicon, a serious off-road package engineered to tackle the most serious of trails right out of the showroom.

    Jeep started by adding front and rear Dana 44 axles with 4.10 gearing and locking differentials that can be activated with the vehicle in low range and traveling at less than 10 mph. A pneumatic pump running at 5 psi mechanically locks the axle shafts together to drive all four wheels at the same speed. When not locked, the rear features a torque-sensing limited-slip differential. Completing the hardware package is a specially designed 4:1 low-range transfer case and heavy-duty driveshafts with 1330 universal joints.

    Goodyear Wrangler "maximum Traction/Reinforced" P245/75R16 31-inch tires are designed with a tread pattern that wraps around the sidewalls to grab ledges along the trail. Constructed with a three-ply sidewall and an advanced silica compound, the Goodyears are engineered for durability and puncture resistance. They add half an inch of ground clearance and are mounted to new dished five-spoke wheels. Four-wheel-disc self-cleaning antilock brakes come standard.

    Visually, in addition to the unique alloy wheels, the Rubicon sets itself apart with diamond-plate sill protectors, a "Rubicon" graphic on the sides of the hood, special interior colors and a four-spoke steering wheel. An additional power outlet is added to the dash, and redesigned seats with more seat-track travel make the Rubicon more comfortable. The rear seats are also revised to tumble and fold more easily and now include a LATCH child-seat anchoring system.

    The Wrangler Rubicon is powered by a 190-horsepower inline six-cylinder engine mated to either a five-speed manual transmission or an automatic. It goes on sale in the summer of 2002.

    Why should you care?
    Unless you're a die-hard off-road fan, you won't have much use for the new Rubicon. Those who use a Wrangler the way God intended will appreciate the factory upgrades included in the Rubicon package. We just like the nice new wheels. — Christian Wardlaw
