How many km did you travel and how many litres did you put in?
It is possible why not?

But you forgot to mention the speed you were going when you got only 4.94L/100km?

Just a few things that affect fuel economy:

Keeping the speed around 90km/h (105km/h on Polo clock could be 95km/h in reality)
Aerodynamics
Outside temperature, humidity
Tyre pressure, type and condition
Flat long roads or hills.
Stop start
Weight the car is carrying
Mechanical condition of the car. ( if new are there any modifications?)
And the most important is the driver's experience and knowledge how to achieve the best fuel economy
