Does the 1.3l fiesta need 8.4l/100km?

Hello in the Ford forum I have a FoFi 1,3l 44kw Bj.02.1994 GFJ and it needs easy 8,4 l on 100 km we also have an Audi80 B4 133Ps and it runs far below the consumption of the fofis and is still 2 years older. Ok I always drive full throttle naja fast is not really fast but ok if it runs times 120 I mean we fly away Have you ever had experiences with it needs your just as much? I wanted so n small car to save money but that was probably nix . Mfg Kathi
