About the 2009 Buick Lucerne
1st generation (2006-2011), fourth model year; meaningful V6 and equipment update year, not a redesign.
Buick positions the Lucerne as a traditional full-size luxury sedan built around quietness, space, and an easygoing ride. The core appeal is a hushed cabin, simple controls, generous rear-seat room, and classic Buick comfort rather than sporty handling. In 2009, that identity still defines the model: it is aimed at shoppers who want a roomy American sedan for relaxed highway travel, with the upper trims adding more power or a richer interior while keeping the Lucerne’s comfort-first character.
The 2009 Lucerne lineup spans the comfort-focused CX, the more upscale CXL, the appearance-focused CXL Special Edition, and the V8-powered Super. The CXL stands out for heated leather-trimmed seats, driver memory, and a heated steering wheel, while the Special Edition adds chrome details and contrast stitching. The Super pairs a 4.6-liter V8 with heated and cooled front seats and model-specific steering and ride tuning.
