2021 Cadillac XT6: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for the 2021 Cadillac XT6 is a new Luxury trim with a 2.0-liter turbo four-cylinder engine, expanding the lineup from two trims to three. The rest of the XT6 receives a light equipment update rather than a redesign.
About the 2021 Cadillac XT6
1st generation XT6 (2020-2025), second model year.
Cadillac positions the XT6 as a stylish three-row luxury SUV for families who want real passenger space without stepping up to the much larger Escalade. The model leans on upscale design, an easy-to-use infotainment setup, and distinct trim personalities rather than off-road focus or extreme performance. Its main draw is combining premium-brand looks and features with practical three-row seating, usable cargo room, and a choice between a simpler luxury setup and a darker, more athletic Sport flavor.
The Luxury trim is the simpler entry point, but it still has three-row seating, a panoramic sunroof, heated front seats, Bose audio, and core driver-assistance features. Premium Luxury adds a V6, leather seating, and extra convenience features, while Sport pairs the V6 with a more advanced all-wheel-drive system, a performance-focused suspension, and gloss-black trim.
