What's interesting to me is that none of those five vehicles are exactly "cars."
Typically, vehicles designed for off-road use are going to have higher fuel consumption than similar-sized vehicles designed to stay on hard-surfaced roadways, as they will have heavier-duty (and heavier) components. If they frequently go off-road, they will suffer more wear and tear on those heavier-duty components, causing more frequent repairs, and each of those repairs will be more expensive because of the heavier-duty (and more-expensive) components.
Vans, even mini-vans, are bigger (and heavier) than cars of similar performance. So there's a similar cost-factor there.
But individual results may vary.
When I saw the headline, I thought that the "champions" might be Corvettes, Shelby Mustangs, Dodge Hellcats (800 hp, I think), and others of that ilk.
