The passenger compartment of the Focus remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of both driver and passenger dummy.  Ford showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions.  In the full-width rigid barrier test, protection of the chest of the driver and rear passenger occupants was rated as adequate, with good protection of all other critical body areas.  In the side barrier test, protection of all critical body areas was good and the Focus scored maximum points.  In the more severe side pole impact, protection was good for everything except the chest, which was adequately protected.  Tests on the front seats and head restraints demonstrated marginal protection against whiplash injuries in the event of a rear-end collision.  A geometric assessment of the rear seats indicated good whiplash protection.  The autonomous emergency braking system performed well in tests of its functionality at the low speeds typical of city driving.  However, the points for AEB City were not awarded as good front head restraint performance is a pre-requisite for the the additional reward for active safety.

Good protection was provided to both the 6 and the 10 year dummies in the frontal offset and side barrier tests, the Focus scoring maximum points for 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.  All of the restraint types for which the car is designed could be properly installed and accommodated in the car.

The bonnet provided predominantly good or adequate protection to the head of a struck pedestrian, with some poor results only on the stiff windscreen pillars.  Protection of the pelvis was also good or adequate, with the bumper scoring maximum points for its protection of pedestrians' legs.  The autonomous emergency braking system performed well or adequately in all tests of its pedestrian and cyclist detection, in daylight and low-light conditions.

The Focus has a seatbelt reminder system as standard equipment.  A speed assistance system uses a camera and a digital map to recognise the local speed limit and allows the driver to automatically set the speed limiter accordingly.  In tests of its functionality at highway speeds, the autonomous emergency braking system performed well in all scenarios.  When the lane assistance system senses that the car is drifting out of lane, it warns the driver and applies a gentle steering correction to correct the path of the vehicle.
