Tested vehicle: 2003 Infiniti FX35 4-door 4wd

The Infiniti FX was introduced in the 2003 model year. There are two models, the FX35 (equipped with a V6 engine) and the FX45 (equipped with a V8 engine).

The Insurance Institute for Highway Safety has evaluated the crashworthiness of the FX in two 40 mph moderate overlap frontal crash tests into deformable barriers. In the first test, the driver frontal airbag deployed late, with the result that high forces were recorded on the dummy's head, indicating the likelihood of head injuries. This led Infiniti to modify the frontal airbag deployment characteristics on models produced after September 10, 2003. Also, Infiniti initiated a service campaign to modify at its cost vehicles produced earlier.

The Institute tested a second FX with the modified driver airbag, and the airbag inflated much earlier. Ratings of the FX are based on the results of the second test, except structural performance is based on both tests.

Action shot taken during the second of two frontal offset crash tests. The side curtain airbag and the side chest airbag on the driver side inflated during the crash.

The dummy's position in relation to the steering wheel and instrument panel after both crash tests indicates that the driver's survival space was maintained very well (second test shown).

The dummy's head lightly contacted the side curtain airbag and its fabric cover during rebound.

Intrusion into the driver's space was minimal, and forces on the legs and feet were low.
