We just returned from slightly more than 2 weeks in Florida. Four adults in the Terrian down and back to Southern Ontario. The Terrian performed very well. I am very impressed with its ride quality and stance at interstate speeds. The 4 cyl had no problems with the hills in the north east. The trip average was 7.9 L/100 Km which is 29.77 MPG (US) and 35.75 MPG (Imp). We typically drive between 65 and 70 mph on the interstate. I did notice a significant drop in mileage if our speed got above 75 MPH which it did on the flat sections of North Carolina and Georga. It's just over 1300 miles each way and we drove from Orlando to Tampa to Fort Myers then back to Tampa while we were there. Total fuel costs was just under $350 which is pretty cheap transportation for 4 people IMO.
