The six toughest braking sections of the 2016 F1 world championship

3/11/2016

 When Formula one drivers break, they are subjected to incredible forces: up to six times their weight

​In the 2016 World Championship, Formula 1 drivers are called to face a variety of about 200 braking manoeuvres, each one distinguished by specific characteristics. During the entire 2015 Championship there were 183 braking sections; this season will combine those with seven more at Hockenheim, which is back on the calendar after a year off, and approximately ten at Baku, the location of the European GP.


Figuring out the Championship's most challenging braking manoeuvres on paper is not an easy task, not even for Brembo, since there can be numerous indicators.


One of the most important, according to Brembo technicians, is the deceleration that the single-seaters and the driver within are subjected to at each bend, called G-force in jargon. The number of Gs is equal to acceleration multiplied by the driver's mass, and represents the force that he is exposed to. For example, with a deceleration of 4-G (four times that of gravity), the driver experiences a force that weighs four times what he would feel when stationary.

​The G-force that the driver's body is subjected to while braking is magnified by the grip and the aerodynamic load. Braking performance being equal, indeed greater load force and grip force contribute to increasing the G-force that the driver experiences. This is why the braking sections with greater G-force are found mainly on the inside of circuits with medium-high aerodynamic load.


On the other hand, on tracks where the drivers reach extremely high speeds, in spite of low aerodynamic load, the G-force is high due to the brutality of some of the  braking sections and the intense reduction in speed. Taking into account the entire 2016 Championship season, there are about thirty turns marked by a negative-G (deceleration) not less than 5, and about fifty that start at 4-G. On the contrary, there are only twelve turns in which the drivers are subjected to less than 1.5-Gs.


The most difficult by far is expected to be the Prima Variante at Monza, or rather the first chicane after the Italian finish line where the drivers arrive at about 350 km/h, followed by a 6-G deceleration. Second to this, in view of data Brembo has available, ought to be turn 12 at the Circuit of The Americas in Austin. Trailing closely behind, with fairly similar numbers, ought to be the Louis Chiron turn (turn 13) in Montreal, the chicane at Eau Rouge in Spa, the Elf turn (turn 1) in Barcelona, and once again Monza with the Variante Ascari.
