Jeep Grand Cherokee

The passenger compartment of the Jeep Grand Cherokee remained stable in the frontal offset test.  Protection was good for all critical body areas of both the driver and passenger.  Jeep demonstrated that good protection would also be provided to the knees and femurs of occupants of different sizes and to those sitting in different positions.  Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the car would be an aggressive partner in a frontal collision and it was penalised accordingly. In the full-width rigid barrier test, protection of the chest of the rear passenger was marginal, based on dummy readings of chest compression.  Otherwise, protection was good or adequate for both occupants.  In both the side barrier and side pole tests, all critical body areas were well protected and the Grand Cherokee scored maximum points in this part of the assessment.  Control of excursion (the extent to which a body is thrown to the other side of the vehicle when it is hit from the far side) was poor. The Grand Cherokee does not have a counter-measure to mitigate against occupant to occupant injuries in such impacts.  Tests on the front seats and head restraints demonstrated marginal protection against whiplash injuries in the event of a rear-end collision. A geometric analysis of the rear seats indicated good whiplash protection.   The Grand Cherokee has an advanced eCall system which alerts the emergency services in the event but lacks a system to prevent secondary collisions.
