A unique version that opens its cargo bed to the sky is the 2004 highlight for GMCs midsize SUV. Envoy shares a basic GM design with the Buick Rainier, Chevrolet TrailBlazer, Oldsmobile Bravada, and Isuzu Ascender. Envoy comes as a 5-passenger regular-length model and as the 7-passenger extended-length XL. The new XUV uses the extended-length body, seats five, and has a power sliding roof section over its cargo area. It also has a midgate wall behind the rear seat that, along with the rear seats, folds to extend the length of the cargo floor. The midgate includes a glass divider window that powers down. XUV has a dual-action tailgate that drops or swings open on side hinges; it also has a power window.
