The passenger compartment of the CX-5 remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of both the driver and passenger.  Mazda showed 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 both the driver and the rear seat passenger was good or adequate.  In both the side barrier test and the more severe side pole impact, protection of all critical body regions was good and the CX-5 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 indicated good whiplash protection there too.  The CX-5 has autonomous emergency braking as standard equipment.  Tests of its functionality at the low speeds typical of city driving at which many whiplash injuries are caused showed good performance, with collisions avoided at all test speeds.

In the frontal offset test, protection of the 10 year dummy was good for the chest and the head.  However, dummy readings of neck tension indicated poor protection of this part of the body.  Protection of the chest of the 6 year dummy was marginal but that of the head and neck was good.  In the side barrier test, both dummies were well protected.  The front passenger airbag is automatically disabled to allow a rearward-facing child restraint to be used in that seating position.  Mazda showed that the system worked robustly and the system was rewarded.  Some universal child restraints should not be used in the front passenger and rear centre seating positions but all restraints tested by Euro NCAP could be properly installed and accommodated in the rear outboard seats.

The bonnet provided good or adequate protection to the head of a struck pedestrian over most of its surface.  The bumper provided good protection to pedestrians' legs while the front of the bonnet showed mixed result in Euro NCAP's tests.  The autonomous emergency braking system can detect pedestrians as well as other vehicles.  In tests of this functionality, the system performed well, nearly gaining full points with collisions avoided in almost every test scenario.

The CX-5's standard-fit autonomous emergency braking system works at highway speeds and performed well in tests of this functionality, with all collisions avoided or mitigated.  The vehicle has a seatbelt reminder for the front and rear seats and a speed assistance system as standard.  A lane assistance system is an option and not included in this assessment.
