    First Take
    This is a twin of the Chevrolet Suburban, which had more agile handling in our testing and better steering and brakes than its predecessor. The ride is supple and controlled. Interior quality and seat comfort are much improved, with seating for up to nine. It can tow a heavy trailer and swallow more cargo than most minivans, but the third row is too low and doesn't fold into the floor. The standard 5.3-liter V8 is powerful but delivered only 14 mpg overall. The selectable full-time 4WD system can remain engaged at all times. ESC is standard. The Yukon Denali models get the 6.2-liter V8 and six-speed automatic for 2009.
