The Wrangler Rubicon performed flawlessly in the rough and rugged. It boasts a cadre of 4WD technology that includes a transfer case designed with a 4:1 low range (the previous off-road version was 3.73:1), which delivers more power at the slow speeds required for off-road driving. Locking differentials, actuated when the driver presses a switch on the dash, prevent power from being directed away from the tires with the best grip. Dana model 44 axles, considered by enthusiasts to be the cream of the crop, come standard on the Rubicon model and are strong enough to handle all manner of off-road conditions.
We drove the new smooth-shifting automatic transmission, as well as the well-geared five-speed manual transmission, and both match up well to the inline six-cylinder engine. Jeep's inline-6 produces ample power in all conditions: 190 horses at 4600 rpm and 235 lbs.-ft. of torque at 3200 rpm.
Boasting Big Foot stature in a mini footprint, the Rubicon wears aggressive Goodyear Wrangler 31-inch tires that help it achieve more than 10 inches of ground clearance on a short (93.4-inch) wheelbase, which makes this a nimble vehicle in the backcountry. Added to that are laudable approach (45-degree), departure (34 degree), and ramp breakover (25-degree) angles. This means you can drive up, down and over steep grades, tall boulders and fallen logs with greater ease.
Off the trail, driving the Rubicon is another matter. The tall tires and off-road suspension, which add capability in the backcountry, become a liability around town. The ride is harsh and choppy. It's a tall step up to get inside and a long reach to access gear stowed in the rear seats. On the plus side, however, is a torque-sensing limited-slip feature on the rear axle for better traction on the road.
We also drove a Wrangler SE with the new 2.4-liter four-cylinder engine. There's not much power here and we wouldn't want to drive all the way across the U.S. in one, but it is an appealing vehicle. The low-cut doors and soft top are cool and it's a more comfortable vehicle than before. And the low price is attractive.
