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

This rating applies to vehicles other than the specific model and body style tested.

The Infiniti EX35 was introduced in the 2008 model year and renamed the EX37 in the 2013 model year because the engine size was increased. The EX was renamed the QX50 beginning with the 2014 model year.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the roof/sunvisor hit was low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy's head contacted the side curtain airbag, which had deployed during the crash, and the roof and sunvisor.

Side crash test ratings can be compared across vehicle categories.

The Infiniti EX35 was introduced in the 2008 model year and renamed the EX37 in the 2013 model year. The vehicle was then renamed the QX50 beginning with the 2014 model year.

Starting with the 2016 model year, the QX50's wheelbase and overall length were increased primarily for more rear seat room. Side ratings are assigned by the Institute based on a test of a 2016 QX50 conducted by Nissan as part of side crash test verification.

Injury measures

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

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

Head protection

Driver — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof and a side airbag that deployed from the seat.

Passenger — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.
