The passenger compartment of the Model Y remained stable in the frontal offset test. Dummy numbers showed good protection of the knees and femurs of both the driver and passenger. Tesla showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions.  Protection of the front passenger was good for all critical body areas.  Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the Model Y would be a benign impact partner in a frontal collision. In the full-width rigid barrier test, the all critical body areas were well protected for the driver and were at least adequately protected for the rear passenger. In the side barrier test, protection of all critical body areas was good and the car scored maximum points in this part of the assessment. In the more severe side pole impact, protection of all critical body areas was good or adequate. 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 found to be adequate. The Model Y has a counter-measure to mitigate against occupant to occupant injuries in such impacts and this performed well in Euro NCAP's test. 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 Model Y 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.

The Model Y provided good protection to both child dummies in both the frontal offset and side barrier tests, 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 Model Y is designed could be properly installed and accommodated in the car.

The bonnet provided good or adequate protection to the head of a struck pedestrian over almost the whole bonnet area, with weak or poor results at the base of the windscreen and on the stiff windscreen pillars.  The protection offered by the bumper to pedestrians’ legs was good at all test locations, as well protection of the pelvis area.  The Tesla Model Y has an autonomous emergency braking (AEB) system which can detect vulnerable road users, as well as other vehicles.  In tests of the system’s response to pedestrians, the system performed well.  In tests of the system’s response to cyclists, the Model Y scored maximum points.

The autonomous emergency braking (AEB) system performed well in tests of its response to other vehicles.  The Model Y has a seatbelt reminder for all front and rear seats.  Its ‘Collision Avoidance Driver Monitoring’ system uses camera-based direct monitoring to detect a distracted driver and automatically changes the sensitivity of the Forward Collision Warning System to be more reactive.  The lane support system gently corrects the vehicle’s path if it is drifting out of lane and intervenes more aggressively in some more critical situations, to avoid road departure.  The car uses digital mapping and camera inputs to determine the local speed limit and the driver can opt to let the system limit the maximum speed accordingly.
