What about Hybrid?

Because the Hybrid is a standardized data collection device, any part of a particular Hybrid type is interchangeable with any other. Not only can one dummy be tested several times, but if a part should fail, it can be replaced with a new part.

Hybrid IIIs are designed to research the effects of frontal impacts, and are less valuable in assessing the effects of other sorts of impacts, such as side impacts, rear impacts, or rollovers. After head-on collisions, the most common severe injury accident is the side impact.

The SID (Side Impact Dummy) family of test dummies has been designed to measure rib, spine, and internal organ effects in side collisions. It also assesses spine and rib deceleration and compression of the chest cavity. SID is the US government testing standard, EuroSID is used in Europe to ensure compliance with safety standards, and SID II(s) represents a 5th percentile female. BioSID is a more sophisticated version of SID and EuroSID, but is not used in a regulatory capacity. The WorldSID is a project to develop a new generation of dummy under the International Organization for Standardization.[12]

BioRID is a dummy designed to assess the effects of a rear impact. Its primary purpose is to research Whiplash, and to aid designers in developing effective head and neck restraints. BioRID is more sophisticated in its spinal construction than Hybrid; 24 vertebra simulators allow BioRID to assume a much more natural seating posture, and to demonstrate the neck movement and configuration seen in rear-end collisions.

THOR offers sophisticated instrumentation for assessing frontal-impacts.CRABI is a child dummy used to evaluate the effectiveness of child restraint devices including seat belts and air bags. There are three models of the CRABI, representing 18-month, 12-month, and 6-month old children.

THOR is an advanced 50th percentile male dummy. The successor of Hybrid III, THOR has a more humanlike spine and pelvis, and its face contains a number of sensors which allow analysis of facial impacts to an accuracy currently unobtainable with other dummies. THOR's range of sensors is also greater in quantity and sensitivity than those of Hybrid III.

One important sector of the traveling public has yet to be represented in mainstream crash testing — pregnant women. The first prototype pregnant crash test dummy has been built by engineering researchers at Loughborough University UK with the aim of improving seat belt design. It has a fluid filled container above the pelvis to replicate the foetus and womb. Belts can be uncomfortable for pregnant women so some choose not to wear them, reducing their safety at a time when it should be increased. A second pregnant crash test dummy has been designed by a student at the University of Idaho
