HYUNDAI claims the Elantra's stronger body improves its crash performance. The stronger, bigger bodyshell features reinforced one-piece centre pillars and an uprated lower dash crossbar. High-tensile steel is used in the doors' side impact intrusion beams. A driver's airbag and front seatbelt pretensioners with a load-limiting device are now standard. Anti-lock brakes and a front passenger's airbag with a passenger presence detection device are optional. Rear disc brakes are only available on the hatch variant. Head restraints and retractable lap-sash seatbelts are provided for all five occupants. The former Lantra base model did without rear head restraints - the rear bench seat of all Elantras now has three. The centre rear seat position made do with a lap-only seatbelt. It now has a retractable three-point belt. Child seat anchor brackets are now fitted to three points in both the sedan and hatch. Previously only one position was utilised.
