The passenger compartment of the Ford Tourneo Custom remained stable in the frontal offset test. Dummy numbers showed good protection of the knees and femurs of both the driver and passenger. Ford did not demonstrate that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions, and protection of this area was downgraded to ‘marginal’.  Analysis of the deceleration of the impact trolley during the test, and of the deformable barrier after the test, revealed that the Tourneo Custom would be a moderately benign impact partner in a frontal collision. In the full-width rigid barrier test, protection of all critical body areas was good or adequate for both the driver and rear passenger.  In both the side barrier and the more severe side pole tests, protection of all critical body areas was good, and the Tourneo Custom 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 good. The Tourneo Custom 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 Tourneo Custom 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.  Ford demonstrated that if the car entered water, the doors, if locked, could be opened within two minutes of power being lost.

In both the frontal offset and side barrier tests, good protection was provided to all critical body areas for both child dummies, apart from the neck of the 10 year old, protection of which was adequate.  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 Ford Tourneo Custom is not equipped with 'child presence detection', a system which issues a warning when it recognises that a child or infant may have been left in the car.  All of the child restraint types for which the Tourneo Custom 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.  Protection of the pelvis and femur was good at all test locations, while that of the knee and tibia was predominantly good.  The autonomous emergency braking (AEB) system of the Ford can respond to vulnerable road users as well as to other vehicles.  In tests of its reaction to pedestrians, its overall performance was adequate.  The system performed well in tests of its response to cyclists, but not for ‘dooring’, where a door is suddenly opened in the path of a cyclist approaching from behind.  Overall, the AEB system performed well in tests of its response to motorcyclists.

Overall, the performance of the autonomous emergency braking (AEB) system was marginal in tests of its reaction to other vehicles, with no points scored in the head-on and crossing scenarios.  A seatbelt reminder system is fitted as standard to the front and rear seats.  The car has an indirect driver status monitoring system, detecting 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.  The driver can choose to allow the limiter to be set automatically by the system, although this is not on by default.
