Makes sense,being an automatic it'll be in overdrive thus not working hard while you're cruising at 40mph.
400km sounds about right,I get 400-440 in my 2200 with a 5 spd. Your fuel mileage will be a little lower because you have an automatic. 400km may not seem like a lot,but for that size of tank,it actually is pretty good.
I used to have a Ford Contour with a 4 cyl and 5 spd,it had a 57L tank and I could get almost 650km to a tank. My 3.1L V6 Rodeo automatic has an 82L tank and it's crying for more fuel around 500km! Thirsty!
