Small overlap front: driver-side

Rating applies to 2018-21 models

Tested vehicle: 2019 Jeep Wrangler Unlimited Sport 4-door 4wd

The Jeep Wrangler was redesigned for the 2018 model year. The previous design was built concurrently through much of the same model year and was renamed the Wrangler JK. Three driver-side small overlap frontal tests of the Wrangler were conducted, two by the Institute and the other by Fiat Chrysler. Ratings are based primarily on the Institute's tests and apply only to the redesigned model.

In both of the Institute's tests, the vehicle tipped onto its passenger side after striking the barrier. The partial rollover presents an additional injury risk beyond what the standard criteria are intended to measure in small overlap frontal crash tests. A vehicle tipping onto its side is not an acceptable outcome for a frontal crash and, as a result, the Wrangler's overall rating was downgraded to marginal.

Action shot taken during the second of two Institute-conducted driver-side small overlap frontal crash tests just before the vehicle tipped on its side.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained well (second test shown).

The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. The combination head and torso side airbag deployed but does not have sufficient forward coverage to protect the head from contact with forward side structure and outside objects. The vehicle lacks side curtain airbags (second test shown).

The driver's space was maintained well, and risk of injuries to the dummy's legs and feet was low (second test shown).

The partial rollover presents an additional injury risk beyond what the standard crash test criteria are intended to measure (second test shown).

Tested vehicle: 2018 Jeep Wrangler Unlimited Sahara 4-door 4wd

The Jeep Wrangler was redesigned for the 2018 model year. The previous design was built concurrently through much of the same model year and was renamed the Wrangler JK. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Fiat Chrysler and apply only to the redesigned model. These ratings also apply to the Jeep Gladiator.
