Outline

BackgroundWorldSID InformationTest DetailsTest Results ObservationsFuture Research

BackgroundFMVSS 214 final rule released in September 2007Updated the dummies and test configurations

Added ES2re (50th male) and SIDIIs (5th female)20 mph oblique pole and MDB test configurations

NHTSA states it will begin evaluations with the WorldSID dummyDynamic pole tests have been conducted in 2007 and 2008 with the same fleet vehicles used to evaluate the ES2re.

ES2re vs WorldSIDHIC 36

Why different?Possible answers

Ford 500-Possible Sensor issue- airbags deployed at different times

WorldSID test- air bag deployed later in the event (22ms vs 37ms)

WorldSID sits differently in the seatVW Beetle and Subaru Forester-
