The Terraza gets a power boost for 2007; the 3.9-liter V-6, which was introduced as an optional powerplant in 2006, is now the standard engine on all models. A flex-fuel model is slated for introduction later in the year and a new CX Plus trim level has been added to the mix. The 2007 Terraza also benefits from redesigned 17-inch, 8-spoke aluminum wheels, one year of OnStar’s Directions & Connections Plan with Turn-by-Turn Navigation, and three new exterior color options.
