Rating applies to 2002-04 models

Tested vehicle: 2000 Nissan Maxima GLE 4-door

The Nissan Maxima and the Infiniti I30 (renamed I35 beginning with 2002 models) were redesigned for the 2000 model year. All 2000 and later Maxima and I30/I35 models manufactured after November 1999 include structural and airbag modifications to improve occupant protection in frontal crashes (note: information about when a specific vehicle was manufactured is on the certification label typically affixed to the car on or near the driver door).

The Insurance Institute for Highway Safety has evaluated the crashworthiness of a Maxima with the structural and airbag modifications in a 40 mph frontal offset crash test into a deformable barrier.

Driver restraints and dummy kinematics

Action shot taken during the frontal offset crash test.

The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained reasonably well.

The seat-mounted side airbag deployed after the frontal airbag did. The dummy's head remained inside the occupant compartment on rebound, so there was no contact between the head and side airbag.

Footwell intrusion contributed to the likelihood of injuries to both lower legs.
