I went and looked up the metric equivalent. That's 8.5 km/l or 14 l/100 km. That's honestly disgusting.
Especially disgusting when you know most people with an F150 use it 90% of the time to go to work, alone, without any 6m rebars in the bed and would be better served by a Yaris that can do 20-25 km/l (ie 45-60 mpg)
