CX and CXL models are powered by an all-new 227-horsepower 3.9L V6. The engine is FlexFuel-capable, which means it can run on gasoline or 85% ethanol. The Super derives its 292 hp from a 4.6L Northstar V8 engine. All Lucernes utilize a 4-speed automatic transmission.
The base CX includes standard amenities like single-zone air conditioning, power programmable door locks, OnStar Turn-by-Turn Navigation and a leather-wrapped steering wheel with audio and cruise controls. New this year is the addition of Bluetooth connectibility. Also standard is Buick's QuietTuning, an engineering initiative that reduces, blocks, and absorbs unwanted outside noises.
Luxury features abound on the Lucerne range, and they're grouped into several large packages. The Comfort and Convenience Package, which is standard on the CXL and Super, is available on the CX and brings heated outside mirrors, dual-zone automatic climate control, a garage door opener, cargo net and power passenger seat.
The Driver Confidence Group, which is standard on the Super and available on the CX and CXL models, includes remote start, ultrasonic rear park assist, heated washer fluid, rain-sensing wipers and StabiliTrak stability control.
The Luxury Package, standard on the CXL Special Edition and Super and available on the CXL, brings heated power front seats with lumbar adjustment and memory, a heated leather steering wheel, and more.
Finally, the Ultra Confidence Package makes available the side blind zone alert and lane departure warning system in all but the CX model.
Standalone options include the blind zone alert and lane departure warning systems, a heated wood steering wheel and heated/cooled seats, and a harman/kardon audio system (which is available on CX and CXL models and standard on Super models).
