I rented a Dodge Grand Caravan GT this weekend and was a little disappointed in the fuel economy. We have a Chrysler Town and Country at work and trips across Ohio to Cleveland from Louisville, KY I regularly get 29-30 mpg doing 75-80 mph. The Dodge was getting about 25 average but there were a=some additional variable as in driving to Charleston, SC more hills and had family in minivan with me so extra weight. I thought losing 3-5 mpg was a bit much though and wonder if the GT has any performance additions that may have taken away fuel economy such as engine or transmission geared to performance possibly. I didn't really drive it hard to see if I could feel a difference in performance.
