The reason I asked the question is because people will buy a small SUV, use it as an SUV once in a while and commute with it most of the time. Because of that, it makes a small SUV a good candidate for some help. I know the pure of heart would only consider a small sedan, but for the convience of having a small SUV, sort of a pickup with a camper shell that can not be removed, and for the fashion statement, they will buy the SUV. All this talk about the best mileage for the small sedans should be extended to small SUV's. There is too much talk about the best mileage an ideal sized sedan can get. This hybrid and diesel stuff should be extended to all SUV's and pickups. You should not have to buy an earth mover sized pickup to get a diesel engine. There would be more savings in fuel if solutions would be applied to the middle of the road vehicles. No matter what you did, they would never become the best, but better is good.
