The passenger compartment of the Mustang Mach-E remained stable in the frontal offset test.  Dummy numbers showed good protection of the knees and femurs of both the driver and passenger.  Ford showed that a similar level of protection would be provided to the legs of occupants of different sizes and to those sitting in different positions.  Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the Mustang Mach-E would be an aggressive impact partner in a frontal collision. In the full-width rigid barrier test, good or adequate protection was provided to all critical body areas.  In both the side barrier test and the more severe side pole impacts, protection of all critical body areas was good and the car scored maximum points for this part of the assessment. The Mustang Mach-E has a centre airbag to mitigate occupant to occupant injuries in the event of a lateral collision.  In Euro NCAP’s test, the airbag worked well, with good protection of the dummies’ heads.  Limitation of the extent to which a body is thrown to the other side of the car in a side impact was rated as marginal.  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 Mustang Mach-E has, as standard, an advanced emergency call system which alerts the emergency services in the event of a crash. The car also applies the brakes after a collision to prevent secondary impacts.

In the both the frontal offset test and the side barrier impact, protection of all critical body areas was good for both child dummies and the car scored maximum points in 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.  One universal child restraint could not be properly installed in the rear outboard seats. Otherwise, all of the child restraint types for which the Mustang Mach-E is designed could be properly installed and accommodated in the car.

A seatbelt reminder is standard for the front and rear seats.  A driver monitoring system monitors steering inputs for signs of fatigued driving.  However, the system is not on by default at the start of every journey and no points were scored.  The autonomous emergency braking system showed good performance in tests of its reaction to other vehicles.    Speed assistance is provided by a system which informs the driver of the local limit, allowing the limiter to be set appropriately.  A lane support system gently corrects the course of a car which is drifting out of lane and also intervenes in more critical situations.
