2009 Buick Lucerne

An alluring approach to style and comfort

2009 Buick Lucerne

On the President George Bush Freeway, which slices through posh North side sections of Dallas, we’re cruising in a center lane while encased in the velvet comforts of the top luxury sedan from Buick, the super Lucerne Super.



1. The Lucerne is offered with a standard 227hp 3.9-liter V6 or an optional 292hp 4.6-liter V8.

2. Pricing ranges from $26,265 to $40,205.

3. The Lucerne Super comes with high-end features like StabiliTrak, a nine-speaker 280-wattt Harman Kardon audio system, heated and cooler front seats, wood trim, Side Blind Zone Alert and GM’s Lane Departure Warning system.

As Buick’s grand-size luxury sedan in front-wheel-drive (FWD) format, the nameplate popped up first on a performance edition of the Lucerne for model-year 2008 outfitted with premium equipment and packing a NorthStar V8 engine plus a tuned chassis with GM’s Magnetic Ride Control (MRC) variable suspension for a refined ride quality.

That NorthStar V8, an aluminum 4.6-liter plant with 32-valve dual overhead cam, romps with 292hp at 5600 rpm and 288 ft-lbs of torque at 4500 rpm. The V8 teams with a four-speed automatic transmission with electronically controlled shift sequences for unobtrusive transitions. Dubbed 4T80, this GM Hydra-Matic permits the application of more engine torque to accommodate the forceful V8.


For 2009, Buick has forged two new trims for the Lucerne: CX and CXL.

Motivation for CX and CXL comes from a more powerful V6 engine with flex-fuel capability to run on 100 percent regular unleaded gasoline, up to 85 percent ethanol (E85) or variations of these two fuels.

The iron-block 3.9-liter V6 delivers 227 hp at 5700 rpm and torque of 237 ft-lbs at 3200 rpm.

A smooth and responsive automatic transaxle, GM’s 4T65 Hydra-Matic with electronic controls, four forward gears and the shifter lever mounted on the steering column, comes with the new V6 in the Lucerne.

The federal Environmental Protection Agency sets the fuel economy numbers for the Lucerne V6 at 17 mpg city and 26 mpg highway using gasoline, or 13 mpg city and 20 mpg highway with E85 ethanol.

The Super edition of the Lucerne extends into Buick’s 2009 line with new safety devices including the Side Blind Zone Alert system and the Lane Departure Warning system, which are added to an upgrade Driver Confidence Package that brings a remote starter and theft-deterrence system, plus Ultrasonic Rear Park Assist, StabiliTrak skid controls and RainSense windshield wipers.

For the Side Blind Zone Alert system, radar sensors mounted on sides of the vehicle emit beams which sweep adjacent traffic lanes to spot any flanking vehicles and then alert the Lucerne driver via a lighted LED icon in the side rearview mirror.

For the Lane Departure Warning system, an on-board camera positioned behind the windshield near the interior rearview mirror notes traffic lane stripes and provides audible signals to alert the driver when the vehicle crosses a stripe to another lane.


The Lucerne’s external styling looks smooth with ripe lines and a bold face focused on a chrome-rimmed grille. The slinky body features Buick’s signature grille with vertical bars in chrome and flanking pairs of shimmering multi-lens headlamps. Below the grille a body-colored fascia contains split air intake ports and round foglamps. A canted hood incorporates striking curves from the headlamps and draws them in taut lines rearward to the base of a raked windshield. Sides reveal smoothly rolled shoulders and arched wheelwells with body-colored molding streaking across the double doors. Chrome-coated portholes on the front fenders, hallmarks in Buick history, denote engine size – three portholes for the V6 and four for the V8. And the line of the roof is a smooth arch that tapers to a rolled tail.

The unit-body structure for the Lucerne has a long wheelbase that extends to 115.6-inches – and those extra inches show up in the passenger compartment with more backseat room to stretch (there’s up to 41 inches of rear legroom).

Within the cabin, the Lucerne reveals an impressive quality of quietness in terms of reducing noise, vibration and harshness (NVH). All external NVH seems to be locked outside, the result of wrapping the passenger compartment liberally with sound-deadening material.

The effort to control NVH inside Lucerne is labeled by the Buick marketing team as QuietTuning and represents a sense of refinement more akin to elite premium cars. Buick’s QuietTuning measures include thick layers of laminate applied to the windshield and all four side windows, adding composite nylon baffles inside all structural roof pillars and rocker panels and cross-car braces, multi-layer steel laminate employed for the dashboard design, along with noise-paring exterior rearview mirrors and low-profile windshield wiper blades.

Lucerne’s cabin also contains fancy gear, either stock or optional, depending on trim level. The standard seat plan shows a pair of bucket seats in front of a bench for three, although CXL issues may be ordered with a three-person front bench split 40/20/40 percent to boost total capacity to six.


For 2009 the base CX model gets added standard features including air conditioning and power controls for windows and door locks, heated power outside rearview mirrors and cornering lamps, six-way power for the driver’s seat and front passenger seat, an extended-range key fob, a stereo kit with CD player and audio controls mounted on the steering wheel, and 17-inch painted wheels.


As for the CXL, it gets rain-sensing windshield wipers, leather upholstery and a twin-zone automatic climate system, the front seats are heated and move eight ways with memory settings, a leather-wrapped steering wheel also has an internal heat element, exterior rearview mirrors carry integrated turn signal indicators and the vehicle rolls on 17-inch premium wheels.

As for the Lucerne Super, it comes with MRC and StabiliTrak, a 280-watt Harman Kardon stereo audio with nine speakers and a six-disc CD/MP3 player, a leather-clad instrument panel with French seam stitching, suede trim on doors as well as the heated and cooled front seats, and real walnut wood trim.


Buick is a brand General Motors hopes will flourish for many years. That is, of course, assuming GM itself is around as a whole. Designed to appeal to the luxury buyer, the Lucerne offers an alluring approach to both style and comfort.

As a driver’s car, it performs well, but never crosses the line into sportiness. That’s a good thing. Given the buyer demographic Buick’s typically reach, good looks and a relaxed environment for driving are significantly more important than speed and agility.

Overall, there is every reason to believe the Lucerne will stand the test of time.
