The 2009 Buick Lucerne has undergone some major transformations since the previous model year like an entirely new engine, upgraded technological features, and even alternative fuel adaptability. A revamped, high-end trim level has been introduced, and former upgrades have become standard features in the latest edition. Overall, the 2009 Lucerne maintains its reputation as a quality full-size sedan, beating out the likes of the Nissan TSX in interior room, but surpasses past model years with more bang for a buyer's buck.

Under the hood of the Buick Lucerne's entry level trim, the CX, buyers can expect a more powerful V6 than 2007's model year. The 3.9L GM 3900 V6 produces up to 233 horsepower and gets around 240-lb per foot of torque. This entry level model also comes equipped with Bluetooth capabilities. Bluetooth enables drivers to utilize their cell phones through a handsfree program installed directly into the vehicle's dash. Also, a new XM Satellite Radio is available with navigation and traffic updates incorporated into the stereo system. This way, drivers will no longer need a separate navigation unit to get directions or find local points of interest.

A long list of safety features are included in the 2009 Buick, but the most impressive are the anti-lock brake system, front and side curtain airbags, an anti-skid program, and traction control. OnStar is still a standard feature on the model and comes equipped with immediate collision alerts. Many insurance companies are now offering discounts to motorists who own vehicles with this innovative safety feature as well.

One of the most talked about new features in the 2009 Lucerne is the available flex-fuel system. This system allows drivers to power their Lucerne with more efficient, cleaner E85 fuel. The ethanol mixture burns cleaner so that fewer pollutants are emitted into the environment. The most attractive feature of this system is that Buick will equip the model with it at no extra charge, while most other manufacturers charge an additional cost to fit their models with the system. With an estimated combined 25 MPG, the Lucerne beats most of the competition. While estimated MPG statistics have not been released for the E85 version, drivers will be happy to know that the fuel economy is certainly even better than the gasoline-powered edition.

The exterior and interior are virtually unchanged in the 2009 Buick Lucerne, but the premier trim - the Lucerne Super - gets a more efficient 4.6L V6 and sportier suspension. By and large, the newest Lucerne is a well rated full-size sedan that can fit the whole family. The lower trims seat six passengers, while the Super trim can seat five. Also, the NHTSA gave this model the coveted five-star frontal crash test rating. List priced at $28,415, the Lucerne should be affordable for most families as well.
