The passenger compartment of the ZEEKR X remained stable in the frontal offset test. Dummy numbers showed good protection of the knees and femurs of both the driver and passenger. ZEEKR showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions. Protection was good for all critical body areas of the passenger. Analysis of the deceleration of the impact trolley during the test, and of the deformable barrier after the test, revealed that the X would be a moderately benign impact partner in a frontal collision. In the full-width rigid barrier test, protection was good for all body areas of the driver and good or adequate for the rear passenger. The X scored full points in the side impact barrier test, with good protection for all critical body parts. In the more severe side pole impact, protection of the chest was rated as adequate and that of other critical areas as good. 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 adequate. The X has a centre airbag mounted on the driver’s seat to mitigate against occupant to occupant injuries in such impacts. Dummy numbers were good in Euro NCAP's test, with equal protection to the front driver and passenger. Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision. A geometric analysis of the rear seats also indicated good whiplash protection. The X has an advanced eCall system which alerts the emergency services in the event of a crash. The car also has a system which applies the brakes after an impact, to avoid secondary collisions. ZEEKR demonstrated that if the car entered water, the doors, if locked, could be opened within two minutes of power being lost and that electric windows would remain functional long enough to allow occupants to escape.

In both the frontal offset and side barrier tests, good protection was provided to all critical body areas for both child dummies, and the ZEEKR X scored maximum points in this part of the assessment.  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.  The ZEEKR X is equipped with a direct 'child presence detection' system, which issues a warning when it detects that a child or infant has been left in the car. All of the child restraint types for which the X is designed could be properly installed and accommodated in the car.

Protection of the head of a struck pedestrian or cyclist was predominantly good or adequate, with poor results recorded only at the base of the windscreen and on the stiff windscreen pillars.  Protection of the pelvis and femur was mixed but that of the knee and tibia was good across the whole width of the car.  The autonomous emergency braking (AEB) system of the ZEEKR can respond to vulnerable road users as well as to other vehicles.  In tests of its reaction to pedestrians, performance was good.  The X scored maximum points for its performance when tested against a cyclist target, avoiding collision in all test scenarios, including ‘dooring’, where a door is suddenly opened in the path of a cyclist approaching from behind.  The AEB system performed well in all tests of its response to motorcyclists and the lane support function also performed well in this regard.

Overall, the autonomous emergency braking (AEB) system of the ZEEKR X performed well in tests of its reaction to other vehicles, although there was no performance in the head-on test scenarios.  A seatbelt reminder system is fitted as standard to the front and rear seats.  The car has a direct driver status monitoring system, and this scored well, detecting driver distraction as well as 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, and the driver can choose to allow the limiter to be set automatically by the system.
