The LaCrosse is comfortable, luxurious and easily the best-looking Buick since the Clinton administration. More important, Buick didn't turn it into a sports sedan something no one ever asked of the brand, and a temptation I'm glad GM didn't give in to. All-wheel drive is optional on the CXL. With this redesign, the LaCrosse moves to a new platform from last year's Chevrolet Impala-based model. The LaCrosse CXL got a 3.0-liter V-6, with a six-speed auto. Safety - Standard safety features include antilock brakes, an electronic stability system, and six airbags. Seat-mounted backseat side airbags are optional, raising the airbag total to eight. A blind-spot warning system and adaptive cornering headlights, which automatically swivel a few degrees to illuminate upcoming curves when you turn the steering wheel, are optional.
