Re: Not a lot!
What Nigel says is true, but at the nicer end of the fuel consumption scale, although no world record, I get about 35mpg at a constant 80mph, well thats what it worked out as when I drove to the South of France and back in the Summer in my 1.6. City driving you'll probably squeeze about 20-25mpg, using steady acceleration and rolling down hills. I too used to have a 1.1 pop fiesta (it was given when I was a student) and in comparison it was very economical
