The passenger compartment remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of both driver and passenger.  Opel showed that a similar level of protection would be provided to occupants of different sizes and to those sat in different positions.  Protection of the driver's chest was rated as marginal, based on dummy readings of chest compression.  In the full-width rigid barrier test, protection of the driver and rear passenger was good or adequate for all critical body areas.  In the side barrier test, protection was good and the Grandland X scored maximum points.  In the more severe side pole impact, protection of the chest was adequate and that of other critical body areas was good.  Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  A geometric assessment of the rear seats also indicated good whiplash protection.  The Grandland X has an autonomous emergency braking system as an option.  The system performed well in Euro NCAP's tests but is not included in this rating of standard equipment.

In the frontal offset test, protection of the 6 and 10 year dummies was good or adequate with the exception of the chest of the 6 year dummy, for which readings of decelerations indicated marginal protection.  In the side barrier test, protection of both dummies was good for all critical body areas.  The front passenger airbag can be disabled to allow a rearward-facing child restraint to be used in that seating position.  Clear information is provided to the driver regarding the status of the airbag and the system was rewarded.  All of the restraint types for which the Grandland X is designed could be properly installed and accommodated in the car.

Good or adequate protection was provided to the head of a struck pedestrian over most of the bonnet surface, with poor results recorded at the base of the windscreen and on the stiff windscreen pillars.  The bumper provides good protection to pedestrians' legs and protection of the pelvis is also mostly good.  The optional autonomous emergency braking system can detect pedestrians and performed well in tests of this functionality but, as it is not standard equipment, an assessment of this system is not included in this rating.

The Grandland X has a seatbelt reminder for the front and rear seats as standard. A lane departure warning system is also standard equipment, as is a speed assistance system which identifies the local limit and allows the driver to limit the speed of the vehicle appropriately.  A more sophisticated system is available as an option which gently corrects the car's trajectory when it is drifting out of lane.  The autonomous emergency braking system is an option and, while it performed well in Euro NCAP's tests, its results are not included in this rating of standard safety equipment.
