YearBody/PowertrainComment
2011 4dr SUT 320-horsepower 5.3L V8
6-speed shiftable automatic 4WD		 what fuel economy? bought it to pull a Brenderup horse trailer (3300lbs including 1 horse) that can be pulled with a 4cyl car in europe.... doing 22l/100km on flat roads with light foot. more than double combined rating ....GM unresponsive!
2007 4dr SUT 320-horsepower 5.3L V8
4-speed automatic 4WD w/low range		 It only averages around 14 to 15 in a mostly city driving environment. Was hoping the V4 mode would kick in more often to help improve the economy.
2007 4dr SUT 320-horsepower 5.3L V8
4-speed automatic RWD		 14MPG in the city sucks.
