It's interesting to note the different overseas front bumper, and the fact that their Rubicon doesn't have the BFGoodrich Rubicon Mud-Terrain tires that the U.S. models come with. The Jeep's performance in mud and dirt would undoubtedly be better if it had a proper set of mud-terrains.
The Wrangler in this video also happens to be a diesel model - I'd kill for one! But in all honesty, I'm satisfied with the performance of my 3.8-liter minivan motor. It's not a fantastic engine, but it does the job and still has more than adequate power even with 35" tires. If I want speed, I'll drive one of my cars.
What I care about is off-road performance, which is the whole reason why I bought a Rubicon.
