Despite the challenges, all the Jeeps survived, which was a big surprise to the owners of highly modified off-road vehicles that were sharing the trail with us. In many spots, the Rubicon isn't wide enough for two-way traffic, so groups of 'wheelers waited as we passed, smirking, expecting the Wranglers to roll, get stuck, or break. None of that happened. Oh, sure, things scraped and the occasional muffler was reshaped, but everything got through. The new engine and trans worked well, and even though peak torque is now at a higher rpm, there was no noticeable difference when off-roading at low speeds.

Jeep's goal with this latest version of the Wrangler was to make the vehicle more refined and better on a day-to-day basis, without sacrificing the JK's off-road ability. The new Wrangler stays true to the model's 71-year-old roots, but now is a lot more fun to drive on-road.
