As the successor of P series, the Q differs considerably from the P-dummies. It is not only advanced in terms of its biomechanical and anthropometric characteristics, it is also developed to be used in both front and side impact testing, making it the first "multi-directional" (child) dummy. The Q series can be equipped with accelerometer, angular velocity transducer, load cell, displacement transducer, etc. to evaluate the injuries suffered in crash tests. The instrumentation is interchangeable within the dummy and between other members of the Q-series.
As the successor of P series, Q3 child dummy is the earliest developed dummy among Q series. Its potential application areas (including side impact test), biofidelity and injury assessment ability are all much better than TNO and P3 child dummy.
