With the Jeep Wrangler Unlimited, you get 20.6 inches of additional wheelbase—a total of 116 inches—plus a bigger rear-seat design, which together takes the Wrangler from essentially feeling like a 2+2 in base form up to a true four- or five-seater. And even when you're not carrying backseat passengers there are other advantages: the ride quality is better and more settled, while you also get a lot more interior space that can be used for cargo.
Otherwise, all the same goodness is here. The most hardcore off-roaders might opt for the Wrangler (in Rubicon trim, of course) over the Unlimited because of its better breakover angles, but all of its other off-road prowess is present—provided you get the right trim and option packages. Just as the standard Wrangler, the Unlimited is only offered with a torquey 4.0-liter V-6, and several soft and hard top choices are available—including the three-piece Freedom Top. This year, two special editions—the Mojave, and the Call of Duty: Black Ops cater to off-roaders who want a distinct look.
