    Buick LaCrosse — Epsilon II (second generation) (2010–2016)

    The second-generation LaCrosse is a four-door sedan in front- and all-wheel drive; the NICB 2010–2016 manuals list it as the CX, CXL and CXS for 2010–2011 (and as the LaCrosse/Allure in Canada for 2010), then by equipment group from 2012 (Base, Convenience, Leather, Premium I to III, Touring; 1SV for 2015 and Sport Touring for 2016). The engines in the rows are the 2.4L four (LAF) and 3.6L V6 (LLT) of 2011, then from 2012 the 3.6L V6 (LFX) and the 2.4L Ecotec four with eAssist (LUK); the 2015 guide pairs each of these two with a 6 speed automatic. The 2015 rows come from GM's 2015 fleet order guide (Wayback Machine captures); every other year comes only from the model-year RPO change lists GM Authority published for 2012, 2013, 2015 and 2016 (the 2012 and 2016 lists credited to GM), so a 2011 or 2014 row is a code those lists delete, rename or describe, middle years without a list are left out of a row, and no source read gives a code for 2010. Trim marks in Notes (O optional, S standard) are the 2015 guide's equipment-group columns: 1SV, 1SB (base), 1SL (Leather, FWD and AWD), 1SP (Premium I, FWD and AWD) and 1SR (Premium II, FWD).
