If you can swing the cost of a suburban, this would be better for 3 kids and the need for room behind the third row. The room behind the third row in the traverse is a true disapointment. I can't go to the grocery store and get groceries without having to lower one of the portions of the third row. In fact my Oldsmobile minivan has more room behind the third row than the traverse. Another plus with the suburban is that even with it being a larger, and heavier vehicle it does not get that much worse fuel economy. I think it get about a mile or two less that the traverse.
Depending on what model year thatís being compared (Iíll use the current model year), here is the fuel economy numbers;
2013 Chevrolet Traverse AWD and 2013 Chevrolet Suburban 4WD.
The 2013 Traverse AWD with the 3.6L, 6 cylinder engine along with the 6 speed automatic transmission has an estimated fuel economy of 16mpg city, 23mpg highway and 19mpg combined.
The 2013 Chevrolet Suburban 4WD with the 5.3L, V8 engine along with the 6 speed automatic transmission has an estimated fuel economy of 15mpg city, 21mpg highway and 17 mpg combined. This is with unleaded fuel not the E85 fuel.
