Buick upgraded the 2014 LaCrosse with ubiquitous LED headlight and taillight accents while the interior received new seats and dashboard. Base models still use the 3.6 litre V6 developing 303 horsepower and 264 lbs.-ft. of torque with a six-speed automatic transmission. The 2.4L four-cylinder used in conjunction with the e-Assist system, and all-wheel drive are still available.
