It’s been about 3 years since Buick wowed us with the gorgeous Avenir concept; a car that was expected to foretell a future flagship sedan for GM’s premium division. Instead, it’s spawned a new sub-brand designating the highest trim level available. The 2018 Enclave Avenir was first and coming early in 2018 is the LaCrosse Avenir. Distinguished by its three-dimensional grille with chrome wings, Avenir script badging and exclusive 19” and 20” wheel designs, Buick says this LaCrosse feeds their customers’ needs for subtle and tasteful details as part of a timeless design. Features available on other LaCrosse models come standard on the Avenir, including a 310-horsepower V-6, nine-speed automatic transmission, navigation and Bose Centerpoint Surround Sound premium audio, as well as a panoramic moonroof.
