The passenger compartment of the Eclipse Cross remained stable in the frontal offset test.  Dummy readings showed good protection of the knees and femurs of both the driver and passenger.  Mitsubishi demonstrated that a similar level of protection would be provided to occupants of different sizes and to those sat in different positions.  in the full-width rigid barrier test, protection of the chest of the rear passenger was rated as marginal, based on dummy measurements of compression but, otherwise, protection of both dummies was good or adequate.  In both the side barrier test and the more severe side pole impact, protection of all critical body areas was good and the Eclipse Cross scored maximum points.  Tests on the front seats and head restraints demonstrated good protection against whiplash injury in the event of a rear-end collision.  A geometric assessment of the rear seats also indicated good whiplash protection.  The standard-fit 'Forward Collision Mitigation' (FCM) system performed well in tests of its functionality at the low speeds typical of city driving, with collisions avoided at all test speeds.

In the frontal offset test, dummy readings in 10 year dummy indicated weak protection of the neck.  The protection of all other critical body areas was good or adequate for both the 6 year and 10 year dummies.  In the side barrier test, protection of both dummies was good and maximum points were scored.  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. Universal child restraints using the adult seatbelt cannot be installed in the rear centre position but, otherwise, restraints could be properly installed and accommodated.

The protection provided by the bonnet was good or adequate at almost every test location.  The bumper scored maximum points for its protection of pedestrians' legs.  Protection of the pelvis was also good at all test points except one, where protection was adequate.  The autonomous emergency braking system ('Forward Collision Mitigation') performed adequately in tests of its functionality when reacting to pedestrians.

The Eclipse Cross has a seatbelt reminder system as standard for the front and rear seats.  A lane assist system warns the driver when the car is drifting out of lane and a driver-set speed limiter helps maintain an appropriate speed.  Tests of the the 'Forward Collision Mitigation' system at highway speeds demonstrated good performance, with collisions avoided or mitigated in all test scenarios and at all test speeds.
