This is an absolutley eloquent vehicle. It appears that one thing that GM has done very successfully with the GMT-900 program is enhance the workmanship of these vehicles. I do not think anyone would argue that the GMT-800's didn't have some of the finest engineering and quality of construction, BUT the problem was that it did not show on the surface. This time around the outside package (including the interior and exterior) demonstrates the same WORLD-CLASS engineering that goes into the rest of the vehicle, ie. the hydro-formed construction, top of the class drive-train, and durability of chasiss.
At first glance and with GM poor photography department, the GMT-900's appear bland in the side profiles, but with a careful eye the level of detail and panel fits is AMAZING. There is nothing bland about these vehicles, GM has a hit on its hands and its competitors are going to be caught with their pants down. Its about time because it has always seemed that the competitors did this to GM.
Another key to remember if the 20/27 MPG numbers are correct is that they did not get all of those improvements from the drivetrain, extensive work went into the design to reduce air turbulance thus increasing the aerodynamic performance of these vehicles.
