2005 Buick LaCrosse
large car / 4-door sedan
Moderate overlap front: original test
Tested vehicle: 2005 Buick LaCrosse CX 4-door
Rating applies to 2005-09 models
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.

Side: original test
Tested vehicle: 2006 Buick LaCrosse CX 4-door with optional front and rear side curtain airbags
Rating applies to 2005-07 models
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.
