The Buick LaCrosse is a large five-passenger sedan similar in size to Chevrolet Impala, Ford Taurus, and Toyota Avalon. At 197 inches long, the LaCrosse is about 7 inches longer than the next largest Buick, the Regal, yielding significantly more leg room. Most LaCrosse models are powered by a 3.6l V6 engine rated at 303-bhp. Buyers willing to trade performance for fuel economy will be interested in the LaCrosse eAssist model which pairs a four-cylinder engine with small electric motor to improve estimated fuel economy to 25/36 (city/highway). Buyers in the snow belt will appreciate that all-wheel-drive is available on six-cylinder models. The LaCrosse is a stylish sedan that compares favorably with its competitors. Models equipped with leather seats start at around $32,000.

The 2012 LaCrosse adds some basic hybrid technology to the 2.4l LaCrosse to improve fuel economy. Power on V6 models has increased to 303-bhp. Trim level and standard equipment changes.
