The RX scored maximum points for its protection of the 1½ year dummy in the dynamic crash tests. In the frontal impact, forward movement of the 3 year dummy, sat in a forward-facing restraint, was not excessive, although dummy readings of neck tension and chest deceleration were marginally high. 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 RX is designed could be correctly installed and accommodated in the car.

The RX scored maximum points for the protection provided to pedestrians' legs and to the pelvic region, with good results being recorded on the bumper and front edge of the bonnet. Head protection was predominantly good or adequate with only a few poor results recorded on the stiff windscreen pillars. The RX has an autonomous emergency braking system that detects pedestrians as well as other vehicles. Euro NCAP will start assesing such systems in 2016 so the system cannot be rewarded here.

All features assessed by Euro NCAP for Safety Assist are standard equipment on the RX: it has electronic stability control; a seatbelt reminder for the front and rear seats; a lane departure warning system; an autonomous emergency braking system that works also at inter-urban speeds and demonstrated good performance in Euro NCAP's tests, successfully avoiding impact against a slower-moving car and a braking car; and road-sign recognition, which advises the driver of the speed limit, although there is no provision for the driver to limit the speed of the vehicle.

The passenger compartment of the RX remained stable in the frontal impact. Dummy readings indicated good protection of the knees and femurs of both the driver and passenger dummy. Lexus 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 test, protection of the driver was good for all critical body areas except the chest, protection of which was adequate. Dummy readings of chest compression indicated weak chest protection for the rear passenger dummy, despite the standard-fit pre-tensioners and load limiters. Protection of the neck was adequate and that of other body areas was good. The RX scored maximum points in the side barrier impact, with good protection of all critical body areas. In the more severe side pole test, protection was still good except for the chest, protection of which was adequate. Tests on the front seats and head restraints demonstrated good whiplash protection in the event of a rear-end collision. A geometric assessment of the rear seats indicated good whiplash protection also for occupants of those seats. The RX has a standard-fit autonomous emergency braking system. In Euro NCAP's assessment of its low-speed performance, impact was avoided at every test speed against a stationary car, and the system scored maximum points.
