The passenger compartment of the Scenic E-Tech remained stable in the frontal offset test. Dummy numbers showed good protection of the knees and femurs of both the driver and passenger. Renault 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 chest of both the driver and passenger was rated as marginal, based on dummy readings of compression.   Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the Scenic E-Tech would be a somewhat 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, for both the driver and 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 marginal. The countermeasure to mitigate against occupant-to-occupant injuries in side impacts 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 indicated good whiplash protection.   The Scenic E-Tech has an advanced eCall system which alerts the emergency services in the event of a crash, and a system to prevent secondary impacts after the car has been in a collision.

In both the frontal offset and side barrier tests, protection of all critical part of the body was good or adequate, both for the 10-year and 6-year dummies.  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 the which the car is designed could be properly installed and accommodated in the car.

The protection provided by the bonnet to the head of a struck pedestrian was predominantly good or adequate, with some poor results recorded on the base of the windscreen and on the stiff windscreen pillars.  The bumper provided good protection to pedestrians’ legs at all test points.  Protection of the pelvis was mixed but predominantly good or adequate.  The autonomous emergency braking system, fitted as standard, can detect vulnerable road users as well as other vehicles.  The system performed well in tests of its reaction to pedestrians and cyclists, with collisions avoided or mitigated in most scenarios.

In tests of its response to other vehicles, the autonomous emergency braking system performed adequately.  A lane support system gently corrects the steering if the car is drifting out of lane and it can also intervene more aggressively in some other, more critical, situations.  The speed assistance system can detect the local speed limit and presents the information to the driver, allowing the speed limiter to be set appropriately.  A seat belt reminder is standard for all seating positions.
