Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Infiniti Q45 was redesigned for the 2002 model year, and the brake pedal was modified beginning with 2003 models to minimize its intrusion in frontal crashes. The car was discontinued after the 2006 model year.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

Dummy movement was well controlled. After the dummy moved forward into the airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.
