To say that today's car market, the best expression of the original four-wheel drive vehicle spirit model, it must be non-Jeep Wrangler is none other than. It has four-door and two-door wheelbase models of the Sahara and Robin Hood. Among them, the two-door model is the most authentic four-wheel drive cross-country replica. Wranglers rely on the retro-style body shape, non-loaded body + transfer box Rock-Trak time-sharing four-wheel drive system advantages, in the hearts of many off-road players occupy a pivotal position. Not long ago, JEEP Wrangler launched a new 2012 model. 
Analysis of main features: body size is different, new leather seats are the highlights
The 2012 Wrangler has no apparent change in appearance compared to the old model. The vehicle size of the 2 door model is 4223x1873x1840mm and the wheelbase is 2424mm. The size of the 4 door model is 4751*1877*1840mm. It is 2947 mm. In terms of off-road capability, the Wrangler's approach angle, passing angle and departure angle are 38 degrees, 22 degrees (18 degrees for the four-door version) and 31 degrees respectively.
In addition to the difference in body size, the Wrangler's differences in the configuration of the entire model are only reflected in the rear seats of the two-door model, which can be put down as a whole, and the rear seats of the four-door model can be scaled down, with a rear cup holder. And back door electric windows. In addition to rear-door power windows, this configuration is different from the differences in the configuration of the body structure. The differences in other functions reflect the different positioning requirements of the 2-door and 4-door models. 
In terms of overall interior design and detail design, though the 2012 Wrangler still continues the rough style of the old models, the details of the design is still bright, and there are also Jeep's signature 7 holes above the interior rearview mirror. The grille, and the Jeep logo on the silver air outlet, even the handrail in front of the first officer marked the Wrangler's birthday. This design also provides JEEP loyal fans with more reasons to choose Wrangler.
In the interior part, compared to the older models, the most important change in the 2012 JEEP Wrangler came from the addition of leather seats, and the addition of seat electric heating buttons under the center console. This configuration is in the cold The north is still very crucial. For the performance of the Wrangler in urban pavement, the function of the leather seat + seat electric heating also improves the comfort of the passenger.
The 2012 JEEP Wrangler chose the Goodyear WRANGLER series of tires for tires. Its main goal is to ensure the tire's grip on muddy road conditions, but its ability to pass through steep slopes and gravel roads is slightly insufficient. The tire size of all models is 245/75 R17. From the tire data point of view, the tire flatness ratio of 75 is also designed for the Wrangler's passability. 
Conventional configuration: The configuration is not rich enough to meet daily driving needs
In the car headlight configuration, all Wrangler models use halogen headlamps and no lenticular lenses are used. This is also based on off-road considerations, as halogen bulbs are easier to replace than xenon headlights. The cost is lower. All models are equipped with front fog lamps and headlights with adjustable height, which improves driving safety performance.
In terms of safety configuration, all Wrangler models use the basic active safety configuration of ABS (Brake Antilock) + EBD (Brake Force Distribution) as well as ESP (Automobile Stability)/ASR (Traction Control). Electronic stability programs, etc., provide sufficient guarantees for safe driving of Wranglers, especially when driving Wranglers to shuttle on non-paved roads. This series of active safety systems ensures driving safety. It is worth mentioning that none of the reversing radars are used in any of the Wrangler models, and this design also shows that the Wrangler is not the location of the urban SUV. 
In the aspect of passive safety configuration, all Wrangler models use only two airbags, one for the pilot and one for the driver, and the protection capability is limited to the front-front collision. Of course, this type of design in the Wrangler model also takes into account the minor collisions that may occur during the off-road process. If airbags of other locations are used at this time, the sudden ballooning of the airbag during driving will inevitably cause greater harm.
It is worth mentioning that none of the JEEP Wrangler models are equipped with electric sunroof as a comfort configuration. Although this type of design limits the Wrangler's comfort, it improves the overall body rigidity and provides more comfort to the rural wilderness. For a strong security guarantee. However, consumers do not have to regret that the entire Wrangler model can be removed through the roof to obtain the effect of convertible models. This design believes that it is better to pull the wind from the panoramic sunroof. The leather steering wheel equipped with the entire system also relieves the off-road process from the discomfort between the steering wheel and the palm to a certain extent, and enhances certain driving comfort.
Four-wheel drive system comparison: Rock-Trak time-sharing four-wheel drive system, Robin Hood equipped with front and rear differential lock
After introducing the major configuration differences, configuration highlights, and configuration upgrades of the JEEP Wrangler, our text on the configuration content has come to an end. From this part of the content, we can easily see that the JEEP Wrangler's launch of the four models in the configuration performance is almost no difference, and the different body structure also created two different styles of Wrangler, so in the configuration link comparison, The choice of two doors or four doors is still based on personal preferences. In the following, we will talk about the difference between Saharan Wrangler and Robin Hood. Both Sahara and Robin Hood have two doors, four doors and two versions. There is no difference in configuration between the two models. Their main difference is from the four-wheel drive system. The JEEP Wrangler adopts the Rock-Trak time-sharing four-wheel-drive system, in which the Rock-Trak is essentially the name of the mechanical transfer case installed in this set of four-wheel-drive systems. There is no differential device in this transfer case. Therefore, when the driver starts the four-wheel drive mode, the transfer case is connected to the front axle rear axle drive shaft. At this time, the transfer case is rigidly connected. Since there is no differential function, when the transfer case is connected, It can also be considered that the vehicle is in the center differential lock state at this time. 
When the vehicle encounters extreme conditions, one side of the wheel loses its adhesion. At this time, under the influence of the differential, the power is distributed to the side of the wheel with the least resistance. Therefore, the wheel that has lost adhesion will madly skid. Adhesive wheels will not be assigned to a trace of power and the vehicle will not be able to escape from it. After locking the mechanical differential lock, the differential is not involved in the work. At this time, the power distribution between the wheels is 1:1, that is, the wheel with a large adhesion has a driving force, and this operation is Can help the car off the hook.
Here, the difference between Saharan and Robin Hood emerged. In the Sahara's four-wheel drive system, only the central transfer case is used. In the limit state, the front axle rear axle power distribution can be fixed at 1:1, but no differential lock is designed for the front axle rear axle. Therefore, before and after The Robin Hood model has a mechanical differential lock on the front and rear axles, so that if one side of the wheel has the adhesion, it can drive the vehicle to disengage. Dilemma. 
Summary: Through the understanding of the JEEP Wrangler, we are now not difficult to choose a model as a recommendation. For those who are pursuing off-roading, the SUV with all-terrain off-road capability is their dream. Looking around the market, the Wrangler Robin Hood models rely on the Rock-Trak time-sharing four-wheel drive system + non-load-bearing body + front and rear axle machinery. The design of the differential lock is far ahead of the 50 million hardcore SUV model camp. The Sahara’s off-road capability is not as good as that of Robin Hood, but the pass-through of the time-sharing four-wheel drive system is obviously better than that of other four-wheel drive systems. Therefore, choosing a Sahara model to freely change roles in urban and rural areas is also a good choice. What’s more important is that Yes, the selling price of 400,000 yuan is also very attractive to consumers. As for the choice of two doors and four doors, if you are an off-road enthusiast, you are advised to choose a two-door model.
