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

The Buick LaCrosse was redesigned for the 2010 model year. Frontal ratings are assigned by the Institute based on a test conducted by General Motors as part of frontal crash test verification.

Injury measures

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

Restraints and dummy kinematics

Dummy movement was well controlled. The driver side curtain airbag deployed during the crash. After the dummy moved forward into the frontal airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.

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.
