What is the Cadillac XT6?
The Cadillac XT6 is a three-row crossover SUV, with space for passengers across the cabin and a rear row for added flexibility. It sits in Cadillac’s SUV range between the XT5 and the larger Escalade. Its crossover layout gives it a family-focused role in the lineup.
The XT6’s first generation ran from 2020 to 2025. Cadillac introduced it as a three-row addition to a range whose SUV names use the XT designation. Its angular exterior styling carries through the brand’s design language.
