The Lucerne CXS is certainly the most enjoyable of the new Buicks to drive, thanks to its powerful V8 engine and Magnetic Ride Control, an adaptive sports suspension developed for the Corvette. Yet we might opt for the Lucerne CXL V6, a very enjoyable car to drive, with agile handling and plenty of performance. The V6-powered Lucerne CXL is positioned to compete against the Toyota Avalon and Lexus ES 330, while the V8-powered CXS aspires to the Lexus GS and Infiniti M luxury sedans.

As it has done from time to time throughout its 103-year history, Buick is rethinking, renewing, revising and rationalizing its model lineup. The Buick Lucerne replaced the Park Avenue and LeSabre when launched as a 2006 model. The Lucerne benefits greatly from the structure and chassis hardware that it shares with the recently launched Cadillac DTS. In this, Lucerne is not breaking tradition but confirming it. The biggest Buicks have shared body structure with Cadillacs since the 1930s, if not before; and they have shared significant chassis pieces since 1965.
