2006 Buick Lucerne
large car / 4-door sedan
Moderate overlap front: original test
Rating applies to 2006-11 models
Tested vehicle: 2006 Buick Lucerne CXL 4-door
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.

Action shot taken during the Institute's moderate overlap frontal crash test.
The dummy's position in relation to the steering wheel and instrument panel after the crash test indicates that the driver's survival space was maintained well (Institute test car shown).
Dummy movement was well controlled in both tests. During rebound, the dummy's head hit only the head restraint, as indicated by smeared greasepaint.
Forces on the lower right leg were high enough to indicate the possibility of injury in the Institute's test (shown). In GM's test, forces on both lower legs were sufficiently high to indicate the possibility of injuries.

View of the vehicle and barrier just after the crash test.
View of the vehicle after the crash with doors removed, showing the side airbags and damage to the occupant compartment.
Smeared greasepaint shows where the driver dummy's head was protected from being hit by hard structures by the side curtain airbag.
Smeared greasepaint shows where the rear passenger dummy's head was protected by the side airbag.
