The demand on the brakes during the GP
Although the lap time is 13 seconds less than the track in Sochi, the difference in the use of the brakes comes to merely half a second: the cars brake for 13 seconds every lap of the Russian GP, while at the Spanish GP they brake for 12,5 seconds. The overall time spent braking on this circuit totals 16%, the same percentage recorded at the Bahrain GP.
The average peak deceleration is 4.5 G; last year it was 4.2 G, which proves that the current single-seaters have a greater amount of brake torque. Hand-in-hand with the increased brake torque this season, we can expect to see more dissipated energy in braking: during the entire GP, each single-seater is expected to dissipate 178 kWh, which is equivalent to the hourly consumption of three dance clubs in Ibiza.
From the starting line to the checkered flag, the Brembo technicians forecast that each driver will face about 530 braking sections, exerting a total force on the pedal of approximately 69 tons.
In other words, each driver will apply a load of more than 700 kg every minute, which is little less than the weight of a single-seater, pilot included.
