The wife and I recently bought a pair of Kia's - a Serento AWD SUV and an Optima EX luxury...both with the 2.4L GDI motor and the active ECO tech. So we've been trying to compare our mileage (hers being the larger and heavier SUV...she's not getting the fuel economy I'm getting so far in the Optima).
