The passenger compartment of the ET7 remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs of both the driver and passenger.  NIO demonstrated that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions.  Protection was good for all critical body areas of the passenger.  Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the ET7 would be an aggressive impact partner in a frontal collision, and the score was penalised accordingly. In the full-width rigid barrier test, protection of all critical body areas was good and the ET7 scored maximum points in this part of the assessment.  In the more aggressive side pole impact, protection of the driver’s chest was rated as marginal, based on dummy readings of rib compressions.  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 ET7 has a counter-measure to mitigate against occupant to occupant injuries in such impacts.  The system performed well in Euro NCAP’s test, with good protection of occupants’ heads.  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 ET7 has an advanced eCall system which alerts the emergency services in the event of a crash and a system which automatically applies the brakes to prevent secondary collisions.

The ET7 provided good protection for all critical body regions of both the 6 and 10 year dummies in the frontal offset and side barrier tests, and 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. All of the child restraint types for which the ET7 is designed could be properly installed and accommodated.

Protection of the head of a struck pedestrian was predominantly good or adequate.  The bumper offered good protection to pedestrians’ legs at all test locations but protection of the pelvis was predominantly weak or poor.  The autonomous emergency braking (AEB) system of the ET7 can respond to vulnerable road users as well as to other vehicles.  The system performed well in tests of its response to pedestrians and cyclists, with collisions avoided in most test scenarios.

The ET7’s autonomous emergency braking (AEB) system performed well in tests of its reaction to other vehicles.  A seatbelt reminder system is fitted as standard to the front and rear seats and the car is equipped with a system to detect 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.  A speed assistance system detects the local speed limit and the driver can choose to set the limiter or let the system do so automatically. [However, the speed limiter failed Euro NCAP’s accuracy requirements at one of the test speeds and that part of the system was not rewarded.  NIO have informed Euro NCAP that all cars will receive revised software to improve the accuracy of the system.
