    Buick LaCrosse — E2XX (third generation) (2017–2019)

    The third-generation LaCrosse is a four-door sedan on GM's E2 platform, built at Detroit-Hamtramck for the 2017 to 2019 model years in front- and all-wheel drive; the NICB 2020 manual lists no 2020 LaCrosse. It came as the base LaCrosse, Preferred, Essence and Premium with the 3.6L V6 (LGX) and an 8 speed automatic; 2018 added the Avenir, a 2.5L eAssist four-cylinder (LHN) with a 6 speed automatic, and a 9 speed automatic for the V6, and 2019 added the Sport Touring. The 2017 rows come from GM's fleet order guide (Wayback Machine captures); 2018 and 2019 come from GM's order guides as posted by GM Authority (the 2018 guide is the March 2017 edition, printed before the Avenir) and from GM Authority's color and changes pages. Trim availability in Notes (O optional, S standard) is from the latest guide that lists the code; Base is the 1SV LaCrosse.
