The THOR-5OM dummy being developed as the next generation dummy for frontal impacts was leased out by NHTSA. This was mounted on a white body of a compact passenger car, and analyzed mainly were motions under relatively severe impact conditions using a HYGE sled at JARI. The characteristics of the THOR dummy were obtained by comparing the results with those of the HyIII dummy evaluated at 30 mph speed under three test conditions: an airbag only, a 3P seat belt only, and a 3P seat belt with an airbag system.
