awd and 4×4 are the same . the 4×2 gets the better mileage. get one with a overdrive for the best mileage.
4X2, but you potentially lose some "utility" with that isn’t an issue then just buy a car, minivan, or wagon which all get better gas mileage.
. Petrol in US will soon be @ $4/gal. And you want an SUV?
oh well, maybe a Toyota?
