    Chevrolet Impala — tenth generation, Epsilon II (2014–2020)

    GM's fleet order guides for the 2014, 2015 and 2016 Impala (Wayback Machine captures) give the factory rows: in 2014 the LS (1LS retail, 1FL fleet), the Eco (1SA, 2SA) with the 2.4L LUK eAssist and the MHH automatic, the LT (1LT, 2LT) and the LTZ (1LZ, 2LZ), with the 2.5L LKW and MH7 or the 3.6L LFX and M7W; in 2015 the Eco is gone and the bi-fuel CNG 3.6L LFR arrives on 2FL and 3LT, with MHG behind the 2.5L; in 2016 the 2.5L LCV with stop-start replaces the LKW and the guide prints no 1LZ column. The repository holds no GM list for 2017 through 2020 (the 2020 guide capture is only the model index, listing the LT 1GY69 and Premier 1GZ69): those years come from GM's 2017, 2018 and 2019 RPO change lists as GM Authority printed them, GM Authority's 2020 changes page (single-source) and the trim codes the NICB VIN manuals print, so most codes carry no year after 2016 and the gaps are not filled by inference. The NICB manuals print two Impala carlines for 2014 through 2016: this car as "Impala" (LS, LS Fleet, LS ECO, 1LT, 2LT, LT ECO, LTZ and LTZ (2LZ) in 2014, then series names with the 1FL, 2FL CNG, 1LS, 1LT, 2LT, 3LT CNG, 1LZ and 2LZ codes, VIN series 1X to 17) and the previous body as "Impala Limited" (LS Fleet, LT Fleet, LTZ or LTZ Fleet and Police Vehicle, VIN series WA to WD, chevrolet/impala-gen9); from the 2018 manual the top trim is the Premier (2LZ), and the 2021 manual prints no 2021 Impala. Downgraded to single-source in review: the 2018 year of the rows that rest only on the narrative package contents of the 2018 GM Authority article, not on its credited 'Official RPO Changes' list, namely the packages Y3W, PI5, SPX, ACZ, WPV and WPW and the codes they include (A45, AG2, AP9, B36, B58, C9B, C9J, DD8, DLG, H0V, H1Y, HV9, KA1, KSG, KU1, KU3, N38, RAL, RQ9, TG5, UD7, UEU, UFG, UFL, UKC, UVD).
