Red Bull F1 team gets fuel-flow clarification from FIA
FIA issues technical directive closing the gray area
On Saturday morning in Austin, the FIA issued a technical directive to the F1 teams detailing a system that Red Bull had proposed that might have allowed the team to run more than the allowed amount of fuel flow.
The system was, of course, rejected by the FIA as being illegal. It is clear, however, that Red Bull did this for a reason, knowing it would be rejected but in order to have the FIA clarify what was acceptable and what was not acceptable and thus draw a line in the sand. Red Bull suspected that other teams might be using such a system, or something similar to it.
Getting more than the allowed fuel flow could create a situation in which a team might be able to burn more fuel at certain points in a race weekend, which would give the engine a little bit of extra power when it was most needed, particularly when accelerating at slow speeds, which would allow the car to carry the additional speed up through the acceleration curve and so produce a higher top speed.
It seems that the system that Red Bull created, based on experiments it conducted, allowed pulses going from the fuel flow meter, which samples what is going on, to be disrupted by external electrical “noise”. This gray area has now been closed and it will be interesting to see if it has any impact on the different levels of performance of the different F1 teams.
