Leon 1.4 TSI extremely high consumption, low final speed

Good evening, today I picked up my new Leon 1.4 TSI and covered a distance of about 1,000 km. I must say, I am very disappointed by the so-called miracle engine. Up to the 4th gear the car proves to be powerful and fast, from the 5th gear it becomes tough, the 6th gear is completely useless. I have driven the vehicle carefully at changing speeds and speeds. Maximum final speed after long running according to Tacho 190 km/h average consumption up to 13 l/100 km Is this normal or should I worry about it? Best regards mapSpain
