Lexus RX

The passenger compartment of the Lexus RX remained stable in the frontal offset test.  Dummy readings indicated good protection of the knees and femurs of both the driver and passenger dummies.  Lexus demonstrated that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions.  Protection of the driver’s chest 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 car would be moderately benign partner in a frontal collision. In the full-width rigid barrier test, protection of the chest of the rear passenger was marginal, based on dummy readings of chest compression but that of other critical body areas was good or adequate.  In the side barrier test, protection was good for all critical body regions and the RX scored maximum points in this test.  In the more severe side pole impact, protection was good or adequate for all critical body areas.  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 adequate. The RX has a counter-measure to mitigate against occupant to occupant injuries in such impacts.  The system worked well in Euro NCAP’s tests, with good protection of the occupants’ heads.  However, Lexus did not demonstrate that the system would provide a similar level of protection in all cases.  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 RX has an advanced eCall system and is equipped with a system to prevent secondary collisions.
