It could be better... Why no medium-duty diesel? see full Hummer H3 review

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

The MPG is not terrible(22-24 combined mpg). But for a small car, most people would expect 30+mpg(28 at the least). see full Volvo C30 review

Ill admit that when I drove the C30 I was driving fast. I rented it for a weekend to see if I wanted to buy it or not. And I went thru an entire tank in less than 200 miles. see full Volvo C30 review
