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.

In both the frontal offset and side barrier tests, good or adequate protection was provided to all critical body areas for both child dummies.  The Grand Cherokee automatically disables the front passenger airbag when a rearward-facing child restraint is put in that seating position.  Tests showed that the system worked robustly and it was rewarded.  All of the child restraint types for which the Jeep Grand Cherokee is designed could be properly installed and accommodated in the car.

Protection of the head was predominantly good or adequate.  The bumper provided good protection to pedestrians’ legs and protection of the pelvis was also good at all test locations.  The autonomous emergency braking (AEB) system of the Jeep can respond to vulnerable road users as well as to other vehicles.  The system performed well in tests of its response to pedestrians and also in tests of its response to cyclists, with collisions avoided in most cases.

The autonomous emergency braking (AEB) system of the Jeep Grand Cherokee performed adequately in tests of its reaction to other vehicles.  A seatbelt reminder system is fitted as standard to the front and rear seats and the car is equipped with a system to detect driver fatigue.  The lane support system gently corrects the vehicle’s path if it is drifting out of lane and also intervenes in some more critical situations.  The speed assistance system identifies the local speed limit, allowing the limiter to be set appropriately.
