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

The Infiniti G was redesigned for the 2014 model year and renamed the Q50. Beginning with 2016 Q50 models, the frontal airbags and driver seat belt were modified. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Nissan as part of frontal crash test verification.

Because the vehicle structure was unchanged, the structure rating is based on results from both this test and an earlier test conducted by Nissan on a 2014 Infiniti Q50.

Injury measures

Measures taken from the neck, chest, and both legs indicate low risk of injuries to these body regions in a crash of this severity. A high head acceleration occurred when the dummy's head hit the steering wheel through the airbag, indicating that head injuries would be possible. Head acceleration from the grab handle hit during rebound was low.

Restraints and dummy kinematics

Dummy movement was well controlled. The driver side curtain and side thorax airbags deployed during the crash. During rebound, the dummy's head hit the grab handle above the side curtain airbag..

Side crash test ratings can be compared across vehicle categories.

The Infiniti G was redesigned for the 2014 model year and renamed the Q50. Side ratings are assigned by the Institute based on a test 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.

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.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.

Low beams

On the straightaway, visibility was fair on the left side of the road and inadequate on the right side. On curves, visibility was good on both right curves, fair on the sharp left curve and inadequate on the gradual left curve.

The low beams never exceeded glare limits.

High beams

On the straightaway, visibility was good on the right side of the road and inadequate on the left side. On curves, visibility was good on the gradual right curve, fair on the sharp right and gradual left curves, and inadequate on the sharp left curve.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
