    Cadillac XT6 — C1XX (2020–2025)

    The XT6 is a Cadillac three-row crossover with a 2.0L turbocharged 4 cylinder or a 3.6L V6 and a 9 speed automatic, sold as Luxury, Premium Luxury and Sport (Wikipedia; NICB VIN manuals 2020 and 2025). The only factory list with RPO codes is the 2025 GM Fleet Order Guide, so every row is dated 2025 and carries trim availability from that guide. The 2021 guide capture shows only the model page (Luxury, Premium Luxury and Sport models), and no source lists RPO codes for 2020 through 2024.
