As Buick’s flagship sedan, the 2020 Buick LaCrosse offers the generous size and accommodations traditionally associated with the brand. Passenger space is copious, with rear legroom rivaling that of some executive-class luxury sedans. Pleasingly, the LaCrosse isn’t a snooze to drive either, which you might otherwise assume given the brand’s history.
2020 LaCrosse: The base LaCrosse comes with dual-zone automatic climate control, 18-inch alloy wheels, 8-way power front leatherette seats, HID headlights, 4G LTE mobile hotspot and an 8.0-inch touchscreen infotainment system with integrated Apple CarPlay and Android Auto.
2020 LaCrosse Preferred: The Preferred adds a power tilt and telescoping wheel as well as a cargo net.

2020 LaCrosse Sport Touring: The Sport Touring trim features a black mesh grille, a rear spoiler, body-color fender vents, and 19-inch black aluminum wheels.

The LaCrosse comes standard with a 2.5-liter four cylinder eAssist mild hybrid system making 194 hp and 187 lb-ft of torque, mated to a six-speed automatic transmission driving the front wheels. The mild hybrid system replaces the alternator with a motor/generator, capable of recouping small amounts of electricity in a lithium-ion battery. The compact electric motor is used for smoother stop/start transitions. The eAssist system is EPA-rated at 25/35 city/highway. The 3.6-liter V-6 engine produces 310 hp and 268 lb-ft paired with a nine-speed automatic and is available with front-wheel drive (20/30) and all-wheel drive (20/29 for the 2018 model) models.
The 2020 LaCrosse received a five-star overall safety rating from the NHTSA (out of a possible five stars). From the IIHS, the LaCrosse received a front crash prevention designation of Superior by the IIHS (Superior is the highest possible rating), with tests performed on a LaCrosse equipped with the Driver Confidence Package 2. The LaCrosse fully avoided a collision in the 12-mph low-speed autobrake test, and in the 25-mph high-speed autobrake test, impact speed was reduced by 24 mph.
As the only remaining full-size sedan in Buick’s lineup, the spacious LaCrosse has room for five. Front- and rear-seat legroom is 42 and 38 inches, respectively. Trunk space in V-6 models measures 15 cubic feet, while the battery in four-cylinder eAssist models reduces space to 14.3 cubic feet. The rear seats fold down in a 60/40 split configuration.
