The passenger compartment remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of the driver and passenger.  Ford 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 impact, protection of both the driver and rear passenger was good or adequate with the exception of the rear passenger's chest, protection of which was marginal.  In the side barrier test, the Fiesta provided good protection to all critical body areas and scored full points.  In the more severe side pole test, protection of the chest was adequate and that of other critical body areas was good.  Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision.  A geometric assessment of the rear seats also indicated good whiplash protection.  An autonomous emergency braking system is available as an option.

In the frontal offset test, dummy readings indicated marginal protection of the neck and chest of the 6 year dummy but, otherwise, protection of it and the 10 year dummy was good.  Protection was also good for all critical body areas for both dummies in the side barrier test.  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 Fiesta is designed could be properly installed and accommodated.

The bonnet provided good or adequate protection to the head of a struck pedestrian over most of its surface.  However, weak and poor results were recorded at the base of the windscreen and along the stiff windscreen pillars.  The bumper provided good protection to pedestrians' legs and the pelvis region was also well protected by the front edge of the windscreen.  A pedestrian-detecting autonomous emergency braking system is available as an option.

A seatbelt reminder is standard equipment for front and rear seats.  The Fiesta has as standard a driver-set speed limiter and a lane keeping system which gently steers the car if it detects that the car is drifting out of lane.  An autonomous emergency braking system is available as an option.
