The 21st and last race of the Formula 1 World Championship is scheduled for November 29th to December 1st at Yas Marina Circuit in Abu Dhabi. The track is on the man-made island of the same name, next to Ferrari World, in the area north-west of the capital of the United Arab Emirates. Even though there are 21 corners, the drivers only use their brakes 11 times each lap.Only the city track in Singapore has more braking points: 15.The brakes are used for a total of almost 18.5 seconds each lap, which equals 17 minutes over the course of the whole race, 19% of the GP. The average peak deceleration per lap is 3.7 G, but taking into account just the first 11 corners, the average exceeds 4.6 G, a figure never approached in the remaining turns.The energy dissipated during braking in the whole GP from each single-seater is 242 kWh, which is quite similar to the Hungarian GP. From the starting line to the checkered flag, each driver exerts a total load of 53.5 tons on the brake pedal.On the single lap though, the load exceeds 970 kg.
Built in 1940, the circuit has been modified throughout the course of the years, most recently in 1990.The cars drive counterclockwise and the straights are fairly short: As a consequence, there is only one occasion when braking is used to drop the speed by more than 200 km/h (124 mph). The track is very drivable with frequent changes in direction, but it also has high-speed turns that don't require use of the brakes. Every lap, the brakes are used barely seven times, but it is not the negative record for the World Championship: in Hockenheim are used five times, in Monza and Montreal six.Overall, during one lap at Interlagos, the brakes are used for almost 12 seconds which comes to 19% of the duration of the race.The presence of few hard braking points results in the average peak deceleration per lap of 3.6 G.Even the energy dissipated in braking by each single-seater during the entire GP is contained: 206 kWh.From the starting line to the checkered flag, each driver exerts a total load of 40 tons and a half on the brake pedal, which is almost identical to the Russian GP.
As per tradition, the MotoGP World Championship will end with the Valencian Community Grand Prix, being held this year from November 15-17. Stage of the race weekend, Circuit Ricardo Tormo is located just outside Valencia and is named for the first world champion rider from Valencia who died prematurely in 1998. Each lap, the MotoGP riders turn to their brakes nine times, splitting fairly evenly the amount of left and right-handed turns: there are five left-handed corners and four right-handed. On one full lap, the MotoGP riders use their brakes for a total of 27 seconds, which is equivalent to 31% of the time needed to complete a lap. The average peak deceleration per lap is 1.16 G, the highest of the four Spanish tracks used in MotoGP. If the section composed of turns 4 and 5 were eliminated, this figure would definitely be higher.Summing up all of the force applied by a rider on the brake lever from the starting line to the checkered flag, the result comes in at about 1,020 kg (2,249 lbs). There are a good seven corners where the load reach at least 4 kg (8.8 lbs).
Formula 1 is back in the United States for the 19th race of the 2019 World Championship from November 1 to 3 at Circuit of the Americas. Located in the hills overlooking the center of Austin, Texas, this track was designed by Hermann Tilke according to recommendations by Kevin Schwantz. The Formula 1 drivers use their brakes on only 9 of the 20 corners, which is three less than the MotoGP riders. The grip guaranteed by the four tires means the cars don't need to brake on turns 3, 6 and 16. To complete one lap on the Austin track, the brakes on each Formula 1 car are applied for 17 seconds, compared to the 37 seconds the MotoGP bikes need. On average during the United States GP, the Formula 1 cars apply their brakes for 16 minutes, which is 19% of the overall duration of the race.The average peak deceleration per lap is 3.8 G, but there are four corners where this gets up to at least 4.7 G. The energy dissipated in braking throughout the GP by one single-seater however, is high: 220 kWh, which is the same of the Bahrain GP. Instead the load applied to the brake pedal by each driver from the starting line to the checkered flag is not among the heaviest in the World Championship: 51.3 tons, which is a quarter less that of the Singapore GP. In other words, each driver is required to apply a force of about 0.546 tons (1,204 lbs) for every minute of driving.
After the race in Japan, the Formula 1 cars move on America for the 18th competition in the 2019 World Championship being held October 25-27 at the Autódromo Hermanos Rodríguez.The track is named for the Rodriguez brothers, Ricardo and Pedro, both Formula 1 drivers who lost their lives prematurely in track accidents. Although the circuit is located 2,229 meters (7,313 feet) above sea level, the altitude doesn't cause any problems for the braking system.What does put the system to the test are the velocity spikes: last year Kimi Raikkonen’s Ferrari car reached 362 km/h (225 mph).Besides speed, the temperature of the tarmac can have a big influence on the temperature of the discs and calipers.During qualifying of two years ago, these got up to 44°C (111°F). Also, the increase in grip on the tarmac during the race weekend typically leads to a rise in the amount of braking torque discharged to the ground.According to Brembo technicians, who have ranked the 21 World Champion circuits, the Autódromo Hermanos Rodríguez is very demanding on the brakes. On a scale of 1 to 5, it earned a 5 on the difficulty index.
