Both the CX and CXL models also receive numerous new standard features. The CXS model of 2008, which used a lower-horsepower version of the Super’s V8 engine, has been discontinued.

The larger of Buick’s two sedan models, the Lucerne is available as the CX and CXL, with 3.9-litre V6, and as the Super, with 4.6-litre V8. Both engines mate to a four-speed automatic transmission.

Features on the CX include 17-inch alloy wheels, air conditioning, heated mirrors with driver’s side auto-dimming, front cornering lights, variable intermittent wipers, cruise control, stain-resistant carpet floor mats, driver information centre, compass, tire pressure monitoring system, auto-dimming rearview mirror, leather-wrapped tilt wheel with audio controls, illuminated vanity mirrors, power windows with driver’s express-down, six-way power driver’s seat, cloth upholstery, CD stereo, Bluetooth hands-free connectivity, power locks with keyless entry, automatic headlamps, traction control, and OnStar with Turn by Turn Navigation plan.

The CXL adds dual-zone automatic climate control, heated mirrors with driver’s side auto-dimming and integrated turn signals, cargo net, heated wheel, garage door opener, driver’s side memory, eight-way power leather seats, and XM satellite radio.

The Super adds 18-inch alloy wheels, fog lights, Super-specific grille and moldings, heated washer fluid system, rain-sensing wipers, power tilt and telescopic heated wheel with wood accents, heated and cooled perforated leather seats with suede inserts, four-way power lumbar adjusters, six-CD Harman Kardon premium sound system, speed-sensitive variable assist steering, remote starter, theft deterrent system, rear parking assist, and StabiliTrak electronic stability control.

With the new 3.9-litre V6 and the discontinuation of the CXS, the Lucerne line slims down but still offers a range of driving experiences, from the more basic CX to the smooth and powerful Super model. Available options, depending on the model, include a sunroof, Special Edition package, and navigation system. The CX and CXL can be optioned with the Super’s standard StabiliTrak stability control, as well as a front bench seat that turns them into six-passenger models.
