Jeep Wrangler Origins
The Jeep Wrangler Unlimited is known as a big offroad sport utility vehicle. The powerful engine on the new models makes it a real contender in the SUV category as its four-wheel drive, skidplates, and high clearance improve its overall value.
Unfortunately, the Jeep Wrangler Unlimited suffers from a few design flaws. The removable soft top is difficult to use and poses a serious security threat by being easy to cut through by would-be thieves. About the Jeep Wrangler Unlimited
The 2012 Jeep Wrangler Unlimited is probably the best of the breed so far. It maintains its strong offroading tradition, and improves the design of the exterior and interior.
The Jeep Wrangler Unlimited is available in three different trim lines: the Sport, Sahara, and Rubicon.
The Sport is the base model that offers sparse features instead of luxury. The Sport comes with 16-inch wheels, front and rear tow hooks for pulling large loads, a six-speaker audio system, CD player, audio jack for music players, and steering-wheel controls.
The Sahara includes everything that the Sport offers but adds a better suspension, a bigger back seat, more trunk space, air-conditioning, and a 60/40 split backseat. A Power Convenience Group package is available that includes power mirrors, power locks and windows, and keyless entry for extra convenience.
The Rubicon adds a lot of off-road ruggedness to the vehicle. It has the base Sport accessories but adds 17-inch wheels, 32-inch tires, a heavy-duty axle that can take a real beating, electronically locking front and rear differentials, rock rails, skidplates, and satellite radio.
Several packages are available for all trim lines, including Bluetooth Connectivity, an iPod and USB interface, and a new trip computer. An optional hardtop that comes apart in pieces is also available.
The Jeep Wrangler Unlimited comes with a 3.6-liter V-6 that produces 285 horsepower with 260 lb-ft of torque, a massive improvement over earlier models. Four-wheel drive is standard as well. All models have a high- and low-gear transfer case, while the Rubicon adds the extra ultra-low-gear transfer case. The Wrangler Unlimited will run zero to 60 mph in 8.8 seconds, which is surprising considering how heavy it is.
The vehicle gets a disappointing 16/20 mpg city/highway, while its regular Wrangler counterparts and the Rubicon get 17/21 mpg city/highway.
Safety continues to be a bit of an issue with the Wrangler Unlimited, especially side impact. Anti-lock brakes come standard, as do stability and traction control and a hill-start assist system to prevent getting stuck in the mud. Front-side airbags are optional, and it’s a good idea to add them.
The doors are the source of the side-impact issues. The Wrangler Unlimited doors do not have the same structural support to protect the driver and passengers as other models in its class. The Insurance Institute of Highway Safety rated the Wrangler Unlimited as the second-worst "marginal" for side impacts.
The interior of the vehicle is still made of easy-to-clean surfaces, but some of the old plastic is now replaced with vinyl. The Wrangler Unlimited has room for three passengers in the back with plenty of legroom, a big improvement over the scrunched two-door wrangler. The four-door Unlimited also has 86 cubic square feet of cargo space with the second-row seat folded forward.
The Wrangler Unlimited is perfect in offroad situations. It is rare to find one of these stuck in even the muddiest and rockiest of terrains. The Unlimited isn’t quite as agile as its two-door counterpart, but it’s still a fun and powerful drive. Jeep Wrangler Unlimited Evolution
The Jeep Wrangler Unlimited was introduced in 2007 as part of the Wrangler’s third-generation line. The Unlimited was larger and had a stiffer body than previous versions of the Wrangler. Its wider body also gives passengers a little more room to breathe. All trim lines were available in the Limited, four-door variant.
The new generation also offers a better engine than previous versions. New vinyl upholstery replaces the old cloth that had been in the vehicle since its inception. Cheap plastic components were also replaced by sturdier materials.
