On the 20th December 2018 DENATRAN (Departamento Nacional de Trânsito) published a new resolution that establishes future vehicle performance requirements in pole side Impacts in Brazil (Resolution 751/18). This new resolution gives the option to comply with Annex II (equivalent to UN R.135) or Annex III (equivalent to FMVSS 214). Although this will be applicable to new vehicle registrations from the 1st January 2030, it is possible to anticipate its total or partial adoption. This paper will focus on the effect of implementing UN R.135 and, specifically, on the differences found by using the WorldSID (World Side Impact Dummy) 50th Percentile Dummy instead of its predecessor (EuroSID-II) for this test. The above-mentioned side impact test will consist of a side impact test at 32 km/h against a rigid pole. The tested vehicle will be rotated 75° from the direction of impact and the only vehicle occupant will be a WorldSID dummy in the driver position.

Studies in the EU and the USA found higher deformation and occupant injuries in frontal crashes when the vehicle was loaded outboard (frontal crashes with a small overlap). Due to that, in 2012 the IIHS began to evaluate the small overlap front crashworthiness in order to solve this problem.A set of small overlap tests were carried out at IDIADA’s (Institute of Applied Automotive Research ) passive safety laboratory and the importance of identifying the forces applied in each structural element involved in small overlap crash were determined. One of the most important structural elements in the small overlap test is the wheel. Its interaction in a small overlap crash can modify the vehicle interaction at the crash, which at the laboratory the interaction is with a barrier. That interaction has a big influence at the vehicle development and design strategy.
