New Fiesta – Engine power extremely bad

My wife bought the new Fiesta 60 HP. The car itself is great, but the engine power is extremely bad. From the 3 gear he does not pull a herring off the plate, comes with difficulty in 4 to 100. When I turn then in 5, is at 130 (after a long time) the end. Lt. papers he should run 152, but reaches in 5 not and in 4 only mountain downhill. That is not normal, isn’t it? In order for him at least a little acceleration, you have to drive the almost always full throttle. Now three times fueled, always through hnitt 8,7 liters / 100. For the lame toad a lot. Can you check the engine power somewhere, if this is all ok? Or is the known that the new 60 hp Fiesta has such bad driving values? Had a 65 hp Corsa, which ran the highway, that was a pleasure. The Fiesta is life-threatening with its extremely lame acceleration.
