The Formula One cars which have entered the market now are heavier than the ones that came out previously. The limit of the minimum weight has been increased but in spite of this struggle is going on to keep the cars under weight. Sauber is the car which is currently over weight now. The probability of increasing the minimum weight was being discussed but is again postponed to the next year.
It was said by Felipe Massa that Adrian Sutil should accuse his own team for the crisis in weight which is creating dangerous circumstances in the races. To follow the new regulations Sutil has to give up on a lot of weight in order to become physically fit to drive. This German would drive at the deserted route without a bottle of drinks to avoid the excess weight and to save every bit of time. He had decided not to drink anything for the Bahrain. He had taken a little of tea for the Malaysia race which was considerably less.
It is known till date that Sauber have been over the new minimum weight of 629 kgs consistently. Both the car and the driver overshoot the limit by around 20 kgs. It is also said that the fault lies in the team and not F1. If the team is there with heavy engine the team members will have to take up the responsibility of doing a better job. So it depends on different teams as to how they mange to be lighter with their cars. It depends on various things and not just the on the drivers.
The teams were not willing to agree on the changes in the weight limit but Sutil mentioned that all the drivers could not unite together and take a collective decision.
