The 2009 Buick Lucerne blends modern yet conservative sheetmetal with a few design cues from Buick’s past, and an understated interior.
“The sleek roofline holds a distinctively-shaped rear pillar,” says Kelley Blue Book. “The wheels fill their wells for a muscular stance, and the portholes are set at a slight angle to accentuate the body's wedgy profile.” Cars.com describes the styling cues in more detail: "a waterfall-style grille that uses thin vertical vanes and includes a chrome Buick tri-shield emblem.” They also note “Chrome portholes—machined and set high in each front fender—are reminiscent of those on historic Buicks...models with V-6 power have three portholes on each side, while V-8 sedans get four portholes per side—a differentiating feature that reaches as far back as 1949."
The Super gets a differently shaped grille that doesn’t impress Autoblog; it "comes to a point pretty far down the Lucerne's face. It looks like a beak to us, which takes away from the Lucerne's otherwise classy styling." Car and Driver is unimpressed as well: “Apart from the reinterpreted portholes, the wedgy shape seems familiar and tired, a repeat of a '90s Camry; only the big-eye look in front saves it from being a complete cliché.”
Automobile describes the 2009 Buick Lucerne's interior as having "quiet taste and subtle style." Car and Driver says it’s “fresh and appealingly minimal” and “very luxurious, especially in Super form, which features niceties such as a leather-finished dashboard and a heated wood steering wheel.”
Edmunds says that “the Lucerne's cabin is handsome and cleanly styled, and boasts simple, friendly controls.” Autoblog likes the Super version’s "interior wraps occupants in luxury including a leather-wrapped upper instrument panel with French-seam stitching, unique finish on the instrument panel center stack, leather seats with perforated suede fabric inserts for the outboard seating positions, and suede door trim inserts."
