Ford Focus ST recommended ?

Buenas stilles, yesterday I had my first test drive with the new FF ST. All in all, I liked the ride. What I noticed negatively was the high fuel consumption. The dealer wanted then also nothing to beautify. ” Such a “strong” engine needs well and likes its 13-15 liters”. Is the Ford technology so far after the others? At the moment I drive a 6 Zyl. BMW with about the corresponding output, only I never consume over 11 liters, since I can do what I want. What does your experience say? As far as equipment is concerned and the car itself, I can’t complain at all, just cream. What does the insurance take? I think a simple 5 cyl should not consume more than 10 l. Always assuming you drive a normal cut. If I’m not mistaken even a turbo is installed that should seem sprite-saving in my view, right? So far I wasn’t convinced to drop my little beamer after a test drive. I’m sorry, but I’m sorry, but I’m sorry, but I’m sorry, but I don’t know what I’m saying.
