Hummer H3 Real Gas Mileage: Cons
YearBody/PowertrainComment
2006 4dr SUV 220-horsepower 3.5L I5
4-speed automatic AWD w/low range		 It could be better... Why no medium-duty diesel? see full Hummer H3 review
2006 4dr SUV 220-horsepower 3.5L I5
4-speed automatic AWD w/low range		 I knew what I was getting into when I bought it. But come on, 14.8mg on the freeway? I would have bought an H2 if I knew that was going to happen. You have to drive like a grandpa to achieve 17mpg. i.e. - under 65 on the freeway. see full Hummer H3 review
