The Buick Enclave is a full-size luxury crossover SUV launched in 2007. The Enclave, the GMC Acadia, and Chevrolet Traverse all share the GM Lambda platform. The Enclave 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 Enclave replaced both of Buick's SUVs, the minivan-based Rendezvous and the truck-based Rainier, as well as the Terraza minivan. As of February 2014, the 2014 Enclave was the top-ranked Affordable Midsize SUV in U.S. News & World Report's rankings.
