The Buick Lucerne is a full-size car manufactured by General Motors from 2005 to 2011. Named for the city of Lucerne, Switzerland, it served as Buick's top-of-the-line sedan until it was replaced by the second generation Buick LaCrosse.
History
The Lucerne replaced the full-size LeSabre and the Park Avenue in the Buick range, and used a revised G platform, nonetheless referred to by GM as the H platform.[1]
The Lucerne was introduced with the standard 3.8 liter Buick V6 (also known as the GM 3800 engine) or optional 4.6 liter Cadillac Northstar LD8 V8 as well as optional active suspension, marketed as Magnetic Ride Control. For 2005, all General Motors vehicles equipped with the 3.8 L V6 become the first SULEV-compliant vehicles.
