The passenger compartment remained stable in the frontal impact. Dummy readings indicated good protection of the knees and femurs of the front seat occupants. However, structures in the dashboard were thought to present a risk to occupants of different sizes and to those sat in different positions. In the side impact test, protection of the chest was adequate while that of other body areas was good. No pole test was done as the H-1 is not equipped with a head-protecting airbag. A geometric assessment of front and rear seats revealed poor protection against whiplash injury in the event of a rear-end collision.
Based on dummy readings in the dynamic crash tests, the H-1 scored maximum points for its protection of the 3 year infant. In the frontal test, forward movement of that dummy, sat in a forward-facing restraint, was not excessive. In the side impact, both dummies were properly contained by their restraints, minimising the likelihood of head contact with parts of the vehicle interior. The front passenger airbag cannot be disabled so a rearward-facing child restraint should not be used in that seating position. The dangers of doing so are clearly indicated inside the vehicle.
The bumper scored maximum points for the protection offered to pedestrians' legs. However, protection provided to the head was predominantly poor, both in the areas likely to be struck by a child and those where an adult's head might strike. Assessment of the front edge of the bonnet was no appropriate owing to shape and size of the vehicle.
The Hyundai H-1 has electronic stability control as standard equipment. However, there is no seatbelt reminder system, even for the driver's seat, and a speed-limitation system is also not available.
