Small overlap front: driver-side

Rating applies to 2007-17 models

Tested vehicle: 2015 Jeep Wrangler Unlimited Sport 4-door 4wd

The Jeep Wrangler was redesigned for the 2007 model year, and a larger, heavier 4-door model was added for the first time.

Driver restraints and dummy kinematics
The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. However, the Wrangler is one of a handful of passenger vehicles still sold without standard side airbags to protect the head and chest from contact with side structure and outside objects.

Action shot taken during the small overlap frontal crash test.

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.

The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. However, the vehicle lacks standard side airbags to protect the head and chest from contact with side structure and outside objects.

Forces on the both the left and right lower legs were just high enough to indicate a moderate risk of injuries.

Action shot taken during the moderate overlap frontal crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained well.

Dummy movement was well controlled. During rebound, the dummy's head hit only the head restraint, as indicated by smeared greasepaint.

Forces on the lower right leg were just high enough to indicate the possibility of injury.

Side

Rating applies to 2007-17 models

Tested vehicle: 2008 Jeep Wrangler Unlimited Sahara 4-door 4wd without optional side airbags

The Jeep Wrangler was redesigned for the 2007 model year, and a larger, heavier 4-door model was added for the first time.

During the crash, the driver door opened. This opening didn't significantly affect dummy movement during the test but shouldn't happen because, in some crashes, it could allow partial or complete occupant ejection, especially if the occupant is unbelted. This door opening resulted in a structure rating downgrade from good to acceptable.

Driver head protection
Although the intruding barrier did not hit the dummy's head in this test, the head was not protected from contacts outside the vehicle. This indicates that only slightly different crash circumstances could produce a direct hit to a person's head.

Rear passenger head protection
The dummy's head was hit primarily by the window frame of the rear passenger door. This impact did not produce high head injury measures, but the head protection is inadequate.

Action shot taken during the side impact crash test showing the driver dummy's head leaning well outward and approaching the window sill. The broken glass is from the window of the driver door.

Smeared red greasepaint shows where the rear passenger dummy's head was hit by the rear door window frame.
