The Fiat Punto model is available in four variants including Active, Dynamic, Emotion and Emotion pack. It is capable of providing mileage of around 14 kmpl in city traffic conditions and around 18 kmpl on highways. However, fuel economy differs from driver to driver, depending on their respective driving behavior.
Sir, if all the engineers are saying that there is a problem in Punto than they might be right, then you should test another Punto in same variant for that problem. If you feel the same problem in the other car also than the engineers are right. But if you won't found the sane in test vehicle, then there Might be a problem with your tyre or wheel or it might be a problem in suspension system. If the problem is with tyre, then it is a regular problem. But you are saying that the problem appears when it just jumps over a bump. By this, it is sounding as a problem with suspension system.
