Step over to the Wrangler Unlimited and you get 20.6 inches of additional wheelbase, for a total of 116 inches. That earns you more cargo space, along with a bigger back seat; so while the standard Wrangler is strictly a 2+2, the Unlimited is a true four- or five-seater, with about the seating space of a compact crossover.
Inside, the Wrangler Unlimited is pretty snug, but four or five can fit reasonably well; you might not find the Unlimited particularly fit for a long road trip, though, the ride can be a bit bouncy or harsh. Seat bottoms and backrests also aren't as kind as those in most vehicles.
Just as in the 2012 Wrangler models, Jeep has introduced an all-new 3.6-liter Pentastar V-6 and new five-speed automatic transmission to the Wrangler Unlimited, and it makes this serious off-roader feel a lot quicker and more composed on the road. The zero-to-60 dash now takes just 8.4 seconds in the Unlimited and 7.7 seconds in two-door Wranglers.
The trail, the sand, and the boulders are of course the Wrangler's reason for being. With several different available drive ratios (including the Rubicon's incredible 4.10:1), a low-speed transfer case, and electronically detachable stabilizer bars, plus a body-on-frame layout and solid axles front and back, the Wrangler Unlimited's off-road capability is unparalleled.
