The passenger compartment of the UX remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs for both the driver and passenger. Lexus showed that a similar level of protection would be provided to occupants of different sizes and to those sitting in different positions. In the full-width rigid barrier test, protection was good or adequate for both the driver and rear seat passenger. In both the side barrier and the more severe side pole tests, maximum points were scored, with good protection of all critical body regions. Tests on the front seats and head restraints demonstrated good protection against whiplash injuries in the event of a rear-end collision. A geometric assessment of the rear seats also indicated good whiplash protection. The standard-fit autonomous emergency braking system scored full points in tests of its functionality at the low speeds at which many whiplash injuries occur, with collisions avoided at all test speeds and overlaps.
