in my local paper there was a article about the new vw vanagon that is only available in europe. It weighed 6500 lbs.and was powered by a inline 5 diesel with 300 ft.lbs. and 170 or so hp. It got 30 mpg. A 2.5 inline 4 cyl in a 4000 lb. ranger should get well over 30. If it doesnt then the engineers are terrible. I guess we will see if they make it or break it.
