Important: Frontal crash test ratings should be compared only among vehicles of similar weight.
The Jeep Cherokee was re-introduced for the 2014 model year after last being sold in the U.S. as a 2001 model.
The driver space was not maintained well, with maximum intrusion of the lower interior of 21 cm at the lower hinge pillar. Upper interior intrusion measured 17 cm at the hinge pillar and 13-15 cm at the instrument panel. The door sill was pushed in laterally 6 cm toward the driver.
Measures from the dummy indicate that injuries to the left knee and left lower leg would be possible in a crash of this severity. The dummy's left forearm skin was cut by the interior door latch.
Restraints and dummy kinematics
The dummy’s head barely contacted the frontal airbag before sliding off the left side as the steering column moved 15 cm to the right, leaving the head vulnerable to contact with forward side structure. Additionally, the seat belt allowed excessive forward excursion of the dummy’s head and torso. The side curtain airbag did not deploy, leaving the dummy's head vulnerable to contacts with side structure and outside objects.
