The GMC Acadia is a full-size crossover SUV from GM. The GMC Acadia, Chevrolet Traverse, Buick Enclave and Saturn Outlook share the new GM Lambda platform. The Acadia went on sale in the United States in December 2006, and in Canada in January, 2007. The Acadia replaces 3 of the 7/8-passenger vehicles on the Pontiac-Buick-GMC dealership network, the mid-size GMC Safari van, the GMC Envoy, and the Pontiac Montana SV6 minivan for the USA Only. As of 2009, the Lambda vehicles have replaced the Buick Rainier, Buick Rendezvous and the Buick Terraza, and then subsequently the GMC Envoy and the Chevrolet TrailBlazer. A Denali version of the Acadia debuted in 2010 as a 2011 model. The Acadia augments GMC with an entry level truck-like SUV and is the first unibody vehicle from the marque. It is also GMC's first front-wheel drive passenger vehicle and GMC's first crossover SUV. The Acadia features seating for eight, generous interior space, and either front or all-wheel drive.
