The 2018 model year Buick LaCrosse Avenir is the luxury version of the standard LaCrosse, coming with unique styling cues, more standard features, and premium materials.
Visual cues that differentiate the two are the meshed grille, lower bumper, rims, and foglight surrounds. Inside, Avenir-exclusive details include a Chestnut interior color theme, embroidered first-row headrests and Avenir-scripted sill plates. Features available on other LaCrosse models come standard on the Avenir, including a powerful 310-horsepower V-6, nine-speed automatic transmission, navigation and Bose Centerpoint Surround Sound premium audio, as well as a panoramic moonroof.
