The 2012 Buick Lucerne, a full-size sedan, was the final iteration of a model line that had been in production for eight years. Launched in 2005 to replace the aging Park Avenue, the Lucerne aimed to offer a blend of classic American luxury, spaciousness, and comfort. While sharing its platform with the Chevrolet Impala and the Pontiac Grand Prix, the Lucerne differentiated itself with Buick's signature design language, featuring a bold grille, swept-back headlights, and a more formal, elegant styling. It offered a choice of two powerful V6 engines, a 3.8L or a 3.9L, providing ample power for highway cruising and towing. The 3.8L engine was mated to a four-speed automatic transmission, while the 3.9L received a six-speed automatic. The Lucerne was available in several trim levels, ranging from the base CX to the top-of-the-line CXL, offering features like heated and ventilated seats, a premium sound system, and a navigation system.

The Lucerne was known for its comfortable ride, spacious interior, and generous trunk space. Its focus on passenger comfort and refinement set it apart from its more sporty platform mates. Despite its comfortable nature, the Lucerne didn't shy away from offering a capable driving experience, feeling solid and secure on the road. While the Lucerne faced stiff competition from other full-size sedans, it remained a solid choice for drivers seeking a comfortable, spacious, and classic American luxury car. However, the market trend towards more fuel-efficient vehicles and the growing popularity of SUVs eventually led to the Lucerne's discontinuation in 2011, marking the end of an era for Buick's large sedan offering.
