2013 Ford Escape 2.0 Ecoboost (see thread in Lightweight section). Have air-springs in rear coils and use a friction type sway bar. At 60mph I get 14mpg on the flats and 10-12mpg on the hills (I fill up a lot because of the 15gallon tank). At 65mph mileage drops by 1-2mpg. Tows fine except in very windy conditions, we definitely get wagged by the tail.
