Front-seat-mounted side air bags and two-row side curtain air bags, which were optional on the 2006 Sequoia, are standard on the 2007 model. The entry-level SR5 model gets a color-keyed grille insert, while the top-of-the-lime Limited gets chrome mirrors. A redesigned Sequoia, based on the new-for-2007 Toyota Tundra pickup, is expected to debut as a 2008 model.
