2021 Buick Enclave: What's New, Specs & Features
Last updated August 4, 2026
The 2021 Buick Enclave is a true carryover with no major product changes from 2020. It keeps the same four trims, V6 powertrain, seven-passenger layout, styling, safety equipment, and infotainment.
About the 2021 Buick Enclave
2nd generation (2018-2024), fourth model year and last year before the 2022 refresh.
Buick markets the Enclave as a premium three-row SUV built around family life, comfort and quietness rather than rugged image or sportiness. Its pitch centers on a smooth V6, a hushed cabin, easy cargo and seating flexibility, and upscale touches that place it above mainstream family SUVs without pushing all the way into full luxury-brand pricing. The Enclave’s main draw is simple: lots of space, easy daily comfort and a more premium feel than a typical midsize three-row SUV.
For 2021, Preferred serves as the practical starting point, while Avenir is the luxury-focused version. Every trim has a 310-hp V6, nine-speed automatic, 8-inch touchscreen, Apple CarPlay, and Android Auto. Premium stands out with a fuller safety suite and massaging front seats, while Avenir adds built-in navigation, wireless charging, upgraded camera views, and richer cabin trim.
