Toyota bZ4X

The passenger compartment of the bZ4X remained stable in the frontal offset test. Dummy readings indicated good protection of the knees and femurs of both the driver and passenger.  However, Toyota did not demonstrate a similar level of protection for occupants of different sizes or those sitting in different positions.  Dummy readings of compression indicated a marginal level of protection for the driver’s chest.  Analysis of the deceleration of the impact trolley during the test, and analysis of the deformable barrier after the test, revealed that the bZ4X would be a moderately benign impact partner in a frontal collision. In the full-width rigid barrier test, protection of the chest of both the driver and rear passenger was rated as marginal, based on measured values of compression. In the side barrier test, protection of all critical body areas was good or adequate. In the more severe side pole impact, protection of the chest was adequate, with good protection of other 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 found to be good. The bZ4X 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 bZ4X 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.
