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

The Buick LaCrosse was introduced in the 2005 model year as a replacement for the Buick Century and Regal. (A limited number of Buick Century models were produced for the 2005 model year.) The Pontiac Grand Prix was redesigned for the 2004 model year and was was discontinued after the 2008 model year.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity. Head accelerations from the roof contacts were low.

Restraints and dummy kinematics

Dummy movement was well controlled. During rebound, the dummy’s head hit the roof in two places.

Side crash test ratings can be compared across vehicle categories.

The Buick LaCrosse was introduced in the 2005 model year as a replacement for both the Buick Century and Regal. (A limited number of Buick Century models were produced for the 2005 model year.) The Pontiac Grand Prix was redesigned for the 2004 model year and was was discontinued after the 2008 model year.

NOTE: In 2006-07 LaCrosse models, side airbags were standard, except in cars sold to fleet buyers that could be ordered without side airbags. Caution: This means that when LaCrosse fleet cars without side airbags are eventually sold, they will be available to retail purchasers. Beginning with 2008 models, side airbags were made standard for retail and fleet buyers.

Side airbags remained optional in all 2004-08 Grand Prix models, and therefore these ratings apply only to Grand Prix models (and 2005-07 LaCrosse models) equipped with the side airbag option.

Injury measures

Driver — Measures taken from the dummy indicate that rib fractures and/or internal organ injuries would be likely in a crash of this severity. A fracture of the pelvis would also be possible, and loading to the shoulder was excessive.

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.
