Cadillac Escalade (incl. ESV) — T1XX, fifth generation (2021–2027)

The fifth-generation Escalade rides on GM's T1XX truck platform and is built at Arlington, Texas, in standard and long-wheelbase ESV bodies; it arrived for 2021, added the supercharged Escalade-V for 2023, lost its Duramax diesel after 2024 and was refreshed for 2025. GM's own lists cover 2023 (a body-builder RPO list that GM Upfitter also files under 2024), 2025–2027 (the fleet order guides, whose trim availability is given in Notes as O optional, S standard) and 2026 (a second body-builder list, whose Chevrolet and GMC package codes are left out). For 2021, 2022 and 2024 the years come only from GM Authority reports on a sample of codes, so a year missing from the Years column means no source was read for it, not that the code was dropped.

The RPO Codes dialogs captured with each 2025–2027 order guide (the …-fleet-order-guide-rpo-codes.txt files, Escalade and ESV) list the same codes and were used to check every code and the Escalade/ESV differences.
