Based on information reviewed by Euro NCAP, a similar level of safety performance can be expected from the Seat Leon ST (estate)
The passenger compartment of the Leon remained stable in the frontal impact. Dummy readings indicated good protection of the knees and femurs of the front seat passengers. Seat showed that a similar level of protection would be available to occupants of different sizes and to those sat in different positions. The Leon scored maximum points in the side barrier test, with good protection of all body regions. In the more severe side pole impact, protection of the chest and abdomen was adequate and that of the head and pelvis was good. The seat and head restraint provided good protection against whiplash injury in the event of a rear-end impact.
The Leon scored maximum points based on readings from the child dummies in the dynamic tests. In the frontal impact, forward movement of the head of the 3 year dummy, sat in a forward facing restraint, was not excessive. In the side impact, both dummies were properly contained by the protective shells of their restraints, minimising the risk of head contact with parts of the car's interior. The passenger airbag can be disabled to allow a rearward-facing restraint to be used in the front passenger seat. Clear information is provided to the driver regarding the status of the airbag and the system was rewarded. The dangers of using a rearward-facing restraint in that seating positions without first disabling the airbag is clearly and permanently indicated.
The bumper scored maximum points for the protection it offered to pedestrians' legs. However, the front edge of the bonnet was marginal or poor in all areas tested. The bonnet offered good protection in most areas likely to be struck by a pedestrian's head.
Electronic stability control is standard equipment and met Euro NCAP's test requirements. There is a standard-fit seatbelt reminder on the driver and front passenger seats. A driver-set speed warning system is available on the Leon but it was not assessed by Euro NCAP as it is not standard on all variants.
