The federal government hasn't yet tested the Wrangler under its revised, and more stringent testing system, but the results that are out there point out that you might have better choices for on-the-road safety. In Insurance Institute for Highway Safety (IIHS) testing, the two-door Wrangler is rated 'good' for frontal impact, 'moderate' in the seat-based rear-impact test, and just 'poor' for side impact; the four-door Wrangler Unlimited has the same frontal and rear ratings but a better (though still worrisome) 'moderate' rating for side impact.
One other surprise shoppers might find in this respect is that side-impact bags remain an option ($430), in a class where they're almost taken for granted. Otherwise, it's all included though, with anti-lock brakes and stability control both on the roster for all Wranglers. Also included are two off-road aids: Hill Start Assist (HSA) to prevent rollback on graded surfaces, and Trailer Sway Control (TSC), which monitors vehicle movement relative to the intended path.
