Platform Heritage

The Buick Enclave is a three-row full-size crossover SUV produced by General Motors since 2007. It was previewed at the 2006 North American International Auto Show, officially as a concept car, making it the first Lambda vehicle to be displayed. The Enclave is partially based on the Buick Centieme concept shown at the 2003 Detroit Auto Show. The first-generation Enclave, the Saturn Outlook, the original GMC Acadia, and the first-generation Chevrolet Traverse all shared the GM Lambda platform. The Enclave replaced both of Buick's SUVs, the minivan-based Rendezvous and the truck-based Rainier, as well as the Terraza minivan. The second-generation Enclave was officially revealed at the 2017 New York International Auto Show.
