Buick's full-size luxury sedan gets a refreshed exterior for 2010 with front and rear fascias, rocker panels and fog lamps previously available only on the Lucerne Super model. Other changes include a different 18-inch chrome wheel design on Lucerne Super.

Other enhancements include backlit gauges on the instrument panel cluster for greater aesthetics and visibility, and available Bluetooth connectivity on the Lucerne 1CX model.

Three new exterior colors will debut; Pearl Frost Tricoat, Light Bronze Metallic and Sand Beige Metallic. All colors except White Opal will be available on the Lucerne Super. The Lucerne CXL Special Edition interior is upgraded to the Custom Perforated Suede-appointed Lucerne Super interior with heated seats standard on both. The 2010 Lucerne is available in CX, CXL, CXL Special Edition and Super models.

Powering Lucerne CX and CXL models is a 3.9L V-6 engine, delivering 227 horsepower and 237 lb.-ft. of torque. The ultimate Lucerne model carries Buick's historic "Super" designation and is powered by a 4.6L Northstar V-8 engine that is rated at 292 horsepower and 288 lb.-ft. of torque.

Lucerne's body structure is engineered to provide maximum occupant protection under a wide range of impact conditions. Active safety and handling features offered on Lucerne include a four-channel anti-lock braking system and traction control; an auto-leveling rear suspension that automatically adjusts the vehicle height for heavy loads; and four-channel StabiliTrak electronic stability control with brake assist, which senses emergency braking situations and boosts the power as needed.
