The LaCrosse lineup starts with the straightforward 1SV, CX, and base models. CXL, Convenience, Leather, and Preferred add everyday comfort and cabin polish, with equipment ranging from practical convenience upgrades to leather and heated seats. Older CXS, Premium III, Super, and Touring models form the loaded, stronger-performance branch. Sport Touring emphasizes darker styling, while Essence, Premium, Premium I, and Premium II focus more on upscale comfort. Avenir sits at the top with distinctive design details and a broader set of luxury features.
The 1SV, CX, and base versions are the simplest, most efficiency-focused LaCrosse models, known for a quiet ride, roomy cabin, and useful everyday equipment.

Buick changed the naming system several times. Early cars used CX, CXL, CXS, and Super. Later versions used names such as Convenience, Leather, Premium I–III, and Touring. The final generation used Base, Preferred, Essence, Premium, Sport Touring, and Avenir.
On newer LaCrosse models, Preferred mainly adds a power-adjustable steering column while retaining the base car’s touchscreen, smartphone integration, power front seats, dual-zone climate control, remote start, and keyless start. It is a modest convenience step, not a major luxury upgrade.
On newer models, Essence is the meaningful cabin upgrade. It adds perforated leather-appointed seats, heated front seats, wireless phone charging, driver memory, and an auto-dimming driver-side mirror over the more basic Preferred trim.
In the third-generation lineup, Premium builds on Essence with ventilated and massaging front seats, extra lumbar adjustment, a heated steering wheel, a head-up display, an air ionizer, and more driver-assistance features, including forward-collision warning and lane-keeping help.
On 2018–2019 cars, Avenir is the more distinct luxury version. It combines V6 power with unique exterior and interior trim, a panoramic moonroof, navigation, Bose 11-speaker audio, wireless charging, an air ionizer, and a head-up display.
No. Sport Touring is mainly an appearance package with a darker grille, distinct 19-inch wheels, and other sportier-looking details. Later examples also use the V6 as standard, but the trim keeps the LaCrosse’s relaxed, comfort-focused character.
On late third-generation cars, Sport Touring emphasizes darker styling, 19-inch wheels, and standard V6 power. Premium focuses on cabin comfort and safety technology with massaging and ventilated front seats, a heated steering wheel, a head-up display, and added driver warnings.
On early second-generation cars, CXL is the more upscale trim. It adds leather-appointed seating, heated front seats, dual-zone climate control, Bluetooth, fog lights, and upgraded mirrors. Some CXL versions also offered all-wheel drive, while CX was the simpler entry model.
In the equipment-group era, Leather adds the upgrades its name suggests: leather-appointed heated front seats. It also brings a power front-passenger seat, keyless access with push-button start, rear parking sensors, driver memory, and an upgraded driver-side mirror.
On later second-generation cars, Premium II builds on Premium I with navigation and more advanced suspension hardware, including adaptive damping and Buick’s upgraded front-suspension design. Both include V6 power, ventilated front seats, a heated steering wheel, and upgraded audio.
In the early equipment-group lineup, Premium III supplies most of the cabin luxury, including a V6, ventilated seats, a heated steering wheel, a rear sunshade, and Harman Kardon audio. Touring goes further with adaptive suspension, navigation, blind-zone warning, and a head-up display.
CXS is the driver-focused upper trim from the early second-generation lineup. It pairs a 3.6-liter V6 and upgraded front suspension with ventilated leather-appointed seats, a heated steering wheel, push-button start, and rear parking sensors.
Super is the high-power version from the first generation. It uses a 5.3-liter V8 with 300 horsepower, firmer suspension tuning, stability control, a rear spoiler, unique trim, heated leather-appointed seats, and an upgraded nine-speaker audio system.
On newer models, Essence is the balanced comfort choice. It adds leather-appointed heated seats, wireless charging, a power-adjustable steering column, and driver memory without moving into Premium’s massaging seats and broader driver-assistance equipment.
For 2018–2019 cars, Avenir is the top luxury trim, with unique styling, richer cabin trim, a panoramic moonroof, navigation, Bose audio, wireless charging, a head-up display, and standard V6 power. In older lineups, Touring or the highest Premium tier filled the top role.
