The title Jeep was given to the vehicle by the soldiers after a dog-like creature called Jeep which could travel anywhere.

Since at that time the new vehicle was highly efficient and had the reputation of driving over difficult terrains, it was termed a jeep. The name was later officially adopted, thus, leading to the present-day jeep wrangler.

Jeep Wrangler Generations, Versions & Models, Body Styles By Year

The First Generation- Civilian Jeep (CJ)

After the remarkable success of the military vehicle, the jeep was introduced for civilian use in 1986. The exact model was released in 1994 and was termed the civilian jeep or CJ. There were some modifications in the CJ model in terms of design to cater to the use of local people. This included the addition of a gear lowering, canvas top, as well as tailgate into the jeep to further boost its performance and improve its aesthetic appeal for civilian use.

However, after a few years of its introduction, there were some speculations and reports regarding the safety concerns of the product. It was highlighted that the jeep has a higher chance of rollover, which can contribute to fatal injuries to the driver and passengers. This impacted the reputation of the civilian jeep and highly affected its safety procedures.

Although tests were carried out later on and all the claims regarding the risk of rollover were proved to be wrong. However, the damage was already done and the overall reputation of the brand was already affected. Hence, it led to lower sales and a lack of consumer trust in the manufacturer. To address the issues, the makers decided to modify the vehicle a bit and changed its name from civilian jeep to jeep wrangler.

The Second Generation – Jeep Wrangler YJ (1986 – 1995)

Now after the modification of the civilian Jeep, the Jeep Wrangler YJ came into the scene. The first model was introduced in 1986 for common use in the Chicago Auto Show and highly inspired the users in terms of design and features. The new version came with some advanced attributes such as anti-roll bars that not only boosted the performance of the vehicle but also improved its overall security practices.

Another significant component of the YJ version included a wider base, and leaf spring suspension, alongside the presence of trackbar suspension. The engine was also improved to a 2.5 liter AMC 150 straight-4 engine. This model continued till 1995 before being replaced by the third generation and kept on upgrading the overall design of the jeep within its functioning years. For example, the standard engine discussed above was replaced with a 4.2-liter AMC 258 straight-6 engine after 1990.

Various other improvements were also carried out during the time period which significantly improved the abilities of the YJ model. Some prominent changes among which include the inclusion of anti-lock brakes in 1992 and three-speed automatic transmission in 1994. Furthermore, the jeep also became safer for riders and was perfect for off-roading. However, what led to the discontinuation of this model was the introduction of square headlights which was not well received by the consumers and led to a decline in its purchase.

The Third Generation – Jeep Wrangler TJ (1996 – 2006)

Now it is time to proceed towards the third generation of the Jeep Wrangler that was introduced right after the discontinuation of the Jeep Wrangler YJ and was termed the Jeep Wrangler TJ. This version of the popular vehicle continued from 1996 to 2006 for ten years and gained wide popularity for its user-friendly design and exceptional features. One of the most loved attributes of this particular version was the replacement of square headlights with circular headlights that were used in the CJ model.

Along with this, new tire options were also presented and an eight-speaker stereo system was also incorporated to offer you full entertainment on long-distance trips with deeper bass and high-quality audio.

Despite this latest addition to the system, the JK model still retained some of the features from the previous models which mainly include the separate body and frame and the part-time four-wheel drive. The earlier versions used a 3.8-liter EGH V6 engine, however, it was later replaced by the 3.6 liter Pentastar V6 engine in 2012.

Moreover, the six-speed manual transmission and four-speed automatic transmission was upgraded to 5-speed automatic transmission in a similar year and significantly enhanced the performance of the vehicle.
