The 2021 Buick Enclave arrives as the fourth model year of the second-generation vehicle, following a mid-cycle refresh introduced for the 2020 model year. Compared to the refreshed 2020 model year, the 2021 Buick Enclave receives a few updates and changes, including deletion of the air ionizer feature.
Introduced with the debut of the second-generation Buick Enclave for the 2018 model year, the air ionizer feature provides improved air quality inside the cabin. The feature works by producing negatively charged particles that attract air-borne contaminants, breaking them down to scrub the air inside the cabin, and thus reducing odors, viruses, dust, pollen, and debris.
Tagged with RPO code KEM, the air ionizer feature was previously offered as standard on Essence, Premium, and Avenir trim levels for the 2020 Buick Enclave. The feature was unavailable on the 2020 Buick Enclave Preferred.
Now, however, with the introduction of the 2021 Buick Enclave, the air ionizer feature has been deleted across the trim level lineup.
Further updates for the 2021 Buick Enclave include the deletion of two exterior colors, as well as the deletion of the advanced twin-clutch all-wheel drive system.
Four trim levels are offered for the 2021 model year, starting with the Preferred, and followed by the Essence and Premium. Sitting at the top of the lineup is the 2021 Buick Enclave Avenir.
Under the skin, 2021 Buick Enclave rides on the long-wheelbase variant of the GM C1 platform, which is shared by the Chevy Traverse and Cadillac XT6. Providing the motivation is the naturally aspirated 3.6L V6 LFY gasoline engine, which is rated at 310 horsepower at 6,800 rpm and 266 pound-feet of torque at 2,800 rpm. Output is harnessed by a nine-speed automatic transmission, with both front-wheel drive and all-wheel available to put the power to the ground.
Production of the 2021 Buick Enclave takes place at the GM Lansing Delta Township facility in Michigan.
