Rating applies to 1997-2006 models

Tested vehicle: 1998 Jeep Wrangler SE 2-door 4wd

The Jeep Wrangler was redesigned for the 1997 model year. As in previous model years, it was available only as a 2-door (the 4-door model was not introduced until the next redesign, in the 2007 model year).

Driver restraints and dummy kinematics
Dummy movement was reasonably well controlled. After the dummy moved forward into the airbag, it leaned toward the driver door. Its head and left shoulder moved outside the door because the doors on the soft-top model tested aren't high enough for optimal restraint.

Action shot taken during the frontal offset crash test.

The dummy's head and left shoulder leaned out of the vehicle after rebounding from the airbag. The problem is the driver door, which is too low to restrain the dummy optimally.

The driver space was maintained reasonably well, with only moderate intrusion into the footwell area.

Red paint on the knee bolster indicates where the dummy's left knee hit, producing moderately high forces on the femur.

Driver head protection
The dummy's head was hit by the window sill of the driver door. This impact did not produce high head injury measures, but the head protection is inadequate.
