The next-generation Jeep Wrangler will undergo few notable modifications, that signifies that new underpinnings are in play.

Up front the hood is extended a bit aft of the front fenders, suggesting a different dash-to-axle ratio for the new off-roader. A matte finish on some of the prototypes also hints that certain body panels may incorporate aluminum to save weight. The new Wrangler isn’t likely adopt a fully aluminum body like the Ford F-150 pickup, but certain parts like the doors, tailgate, fenders, and hood are expected to use the lightweight material.

Another significant change is a new suspension setup that’s visible in the rear. The current Wrangler’s rear crossmember is absent from these mules, making us think that the new SUV will use a different rear suspension geometry, though it’s too early to tell what that might be. The Jeep Wrangler currently uses a live axle with coil springs, trailing arms, and a stabilizer bar.

The 2018 Jeep Wrangler is expected to arrive in early 2018, possibly at the Dtroit Auto Show.
