Most of Jeep's Wrangler mules have been four-door 'Unlimited' models.

[Update: We have obtained some additional photos of the 2-door Jeep Wrangler in profile. They have been added to the gallery.]The two-door version of the 2018 Jeep Wrangler has finally been spotted again, and as we creep ever closer to the new 4x4's unveiling, we're getting more and more of Jeep's mules to look at.

This is the most we've seen of a two-door model so far, but it's not like the Wrangler is a platform historically known for styling surprises. If you told us this was just an elaborate cover-up job of a current-generation model, it would require effort on our behalf to dispute that claim.

Really, the most important thing about this sighting is that it happened at all. The absence of two-door mules was becoming somewhat conspicuous. With the pickup model already being held back a model year after the traditional Wrangler's release, many were starting to wonder if more delays were going to materialize. After all, the four-door Wrangler is the nameplate's bread-and-butter these days. A wait for the two-door wouldn't have been all that surprising.

Quite a bit about the new Wrangler's engineering remains a mystery. We're not certain how extensively lightweight materials (most notably aluminum) will be employed, nor are we completely certain of the final powertrain variants. For the time being, we expect two gasoline engines (four- and six-cylinder, specifically) and a diesel model. We wouldn't call the last a certainty at this point, however, given FCA's recent diesel woes. A plug-in hybrid may not be entirely out of the question, either.

We do know, however, that the 2018 Wrangler is pretty close to production-ready based on the fact that these mules appear to be running around with full interiors. 2018 is just around the corner, so we don't expect we'll have to wait too long to learn the rest.
