In order to keep up with the competition and also allow it to meet the latest safety standards, the upcoming Wrangler is going to be an all new model. While many people are excited about it, the new model is not going to be perfect. In fact, Jeep is going to take some great features of the car in the sake of safety and fuel efficiency but more on that later. The largest change for the upcoming 2018 Jeep Wrangler is going to be the move to an aluminum body. This has been rumored for a long time and only recently Jeep confirmed it.
