2011 Buick Lucerne

Tested vehicle: 2006 Buick Lucerne CXL 4-door
Rating applies to 2006-11 models

The Buick Lucerne was introduced in the 2006 model year as a replacement for the Buick LeSabre and Park Avenue. The Cadillac DTS was introduced in the 2006 model year as a replacement for the Cadillac DeVille.

Two moderate overlap frontal tests of the Lucerne were conducted, one by the Institute and the other by General Motors. Ratings are based on both tests.
