The Hyundai Santa Fe is the sister car to the Sorento. I like my brand new 2010 version, but the 4 banger is slightly underpowered. We recently put over 2,000 miles on it on a trip and only averaged about 25.5 MPG with the 4 cylinder and FWD (not the AWD version). Disclaimer, we were loaded (four passengers and the back was packed), and the trip was a lot of hills and passing slower vehicles on two-lane roads (kicking down a couple of gears). The V-6 would likely have done just as well on this trip for mileage.
In all, we really liked the car. Plus, the little covered storage bin in the bottom of the back can hold a home defense shotgun (with extra skeet barrel and full stock), an SKS - with TAPCO 922 compliance stock, a Winchester 94 carbine, a Ruger 10/22 with scope, some ammo, targets, hearing and eye protection, and a .40 cal pistol in the box. It closed down tight and you'd never know the stuff was in there. My buddies were impressed.
The V6 is too much fun to drive. I just could not go back to a I4.
