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

The Nissan Altima was redesigned for the 2007 model year. Two tests of the Altima were conducted, one by the Institute and the other by Nissan as part of frontal crash test verification. Ratings are based on both tests.

Injury measures

In each test, measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head acceleration from the roof rail hit was low in the test conducted by Nissan.

Restraints and dummy kinematics

Dummy movement was well controlled in both tests. During rebound in the test conducted by Nissan, the dummy's head hit the roof rail. During the test conducted by the Institute, the driver side curtain and thorax airbags deployed, and the dummy's head rebounded into the side curtain airbag without coming close to any stiff structure that could cause injury.

Side crash test ratings can be compared across vehicle categories.

The Nissan Altima was redesigned for the 2007 model year. Beginning with 2010 models, the body side structure was modified to improve occupant protection in side impact crashes. Side ratings are assigned by the Institute based on a test conducted by Nissan as part of side crash test verification. The car tested was a 2009 model fitted with the improved body side structure and was representative of production 2010 models.

Injury measures

Driver — Measures taken from the dummy indicate that rib fractures as well as a left femur fracture would be possible 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.
