2007 Jeep Wrangler

Most automakers have one: an iconic model that historically, or currently, embodies the spirit and essence of their brand. BMW has its 3-series, Porsche has the 911, and Jeep has the Wrangler. With so much symbolically riding on this single model, it was imperative for Jeep not to screw it up - especially considering how much the introduction of the front-wheel-drive, unibody Compass cute-ute has irked the Jeep faithful.

But Jeep made it adamantly clear that the new Wrangler is no watered-down, sissified pretender. Whereas all the other current Jeep models have abandoned solid front axles, the Wrangler still proudly rides on front and rear Dana axles, a Dana 30 front and Dana 35 rear. The Rubicon model sports Dana 44s front and rear, as do any models with the tow package.

Incorporating a version of the system first showcased on the Dodge Ram Power Wagon, the Wrangler offers an electronically disconnecting front stabilizer bar - Active Sway Bar System (ASBS) - delivering additional wheel travel for traversing the toughest trails. Thanks to this bit of techno-wizardry, the new '07 Jeep Wrangler boasts a 652 ramp travel index with the front stabilizer bar engaged and an 832 RTI with the front stabilizer bar disconnected - a 28-percent increase. Jeep claims an approach angle of 44.3 degrees and a breakover angle of 25.4 degrees, along with a 40.4-degree departure angle.

For the (few) fans of the four-cylinder Wrangler, there is some bad news for 2007. The four-banger is discontinued, at least for now. Though many expected the venerable 4.0L inline-six to be replaced with the 3.7 SOHC 90-degree V-6 widely used in the Dakota and Liberty, the new Wrangler will have a version of the 60-degree, 3.8L pushrod V-6 out of the minivans. In the Jeep application, the engine produces 205 hp at 5,200 rpm, and 240 lb-ft of torque at 4,000 rpm, an increase of 15 hp and 5 lb-ft, respectively.

The Rubicon model features a Rock-Trac NV241 two-speed transfer case with a 4.0:1 Low-range gear ratio, as well as electric front- and rear-axle lockers and 32-inch BFGoodrich Mud Terrains. The X and Sahara models feature the second-generation Command-Trac NV241 part-time, two-speed transfer case with a 2.72:1 Low-range gear ratio. In addition, a Trac-Lok limited-slip rear differential provides extra torque and grip during low-traction situations, such as driving over sand, gravel, snow, or ice.

Much to the chagrin of hardcore Jeepers, some electronic nannery has made its way onto the Wrangler but may actually be of some benefit off-road. Standard on the new Wrangler is an Electronic Stability Program (ESP), which aids the driver in maintaining vehicle directional stability in severe driving maneuvers on any type of surface. Thankfully, the ESP features three modes: Full On, Full Off, and Partial On. Also making its debut on the Wrangler is Electronic Roll Mitigation - a system that observes and monitors the vehicle roll attitude and lateral force to estimate the potential for a rollover situation. If necessary, the engine torque is reduced, and a short burst of full braking is applied to the appropriate wheel to help stabilize the vehicle attitude and reduce the vehicle's lateral force.

New four-wheel-disc antilock brakes are standard on all new Wrangler models. An off-road antilock braking feature enables sustained wheel lockup for improved performance on plowable surfaces, including loose dirt, gravel, sand, and mud.

Although Jeep heavily emphasized the increased capabilities of the new Wrangler, it did not neglect upgrading the comfort and convenience features, traditionally a weak point for the Wrangler.

A 2-inch-longer wheelbase, 3.5-inch-wider track, and 5.5 inches more overall width allowed for 4.6 inches more hip and 5.1 inches more shoulder room, as well as an additional inch in rear-seat legroom and 2 inches more cargo storage length behind the rear seat. Addressing what's long been a shortcoming of the Wrangler, the new model features a lockable underfloor storage area behind the rear seat.

Much to the delight of cheerleaders and sorority girls everywhere (ironically another strong constituency of Wrangler owners), an all-new, three-piece modular hardtop system features three configurable panels - left- and right-front passenger panels and a rear panel - providing more options for open-air driving in the all-new '07 Jeep Wrangler. Jeep claims removing the left- and right-front passenger panels is simple and can be accomplished quickly by one person.

Sure to delight backcountry rockhounds and ditzy blondes alike is the availability of an optional full-screen navigation system and Sirius satellite radio. Also a Wrangler first, power windows and door locks are available. But fear not, the doors are still removable, and yes, you can still get optional half doors.

So, does Jeep's new icon have the trail moxie to run with its predecessors? Jeep certainly thinks so. As soon as we get a chance to get behind the wheel of one, we'll let you know what we think. Look for the new Wrangler to roll into dealerships in the fall of '06.
