The next season the cars of Formula 1 must weigh a minimum of 722 kilograms, 20 more than at present and the whopping 117 kilograms more than in 2009. With the arrival of energy recovery systems (KERS and now ERS), the FIA has been increasing steadily the weight of the cars. In 2017, with the new tires, it is expected an increase of five kilograms only in that section and it makes the car less agile and more difficult to stop.
In the past, Singapore Grand Prix, in which the cooling of the brakes is critical for the appearance of the circuit and how hard it is to overtake, there were several riders that were problems to keep the temperature of your brakes under control.
One of them was Lewis Hamilton, who states that he spent a large part of the race with problems and not able to push its rivals so as not to suffer a dropout. “It started to overheat, so I had to slow down, I could only see the other guys away while I thought of different ways to try and keep them under control (the brakes). I was able to do it temporarily when I did my second or third stop, but towards the end even had a little hot”.
Lewis Hamilton goes further and expresses concern about what will happen in 2017, with cars 20 kilograms heavier this year. “I Think that what comes to mind is how much to make the situation worse the next year when we have cars heavier. It is a shame that the cars are so heavy, because you can’t tighten, you can’t compete well when you go behind the other”, said the briton.
The teams are trying to minimize at maximum the size of the brake ducts because exert a very negative effect on the aerodynamics of the car, causing a lot of air resistance and, therefore, penalizing the tip speed and creating turbulence that foul flows aerodynamic circulating in the direction of the rear of the car.
