Continuing the discussion about the fuel flow rate of 100kgs per hour, Red Bull boss Christian Horner has suggested that the easiest way to ensure that all teams are not caught out by a drifting sensor is to eliminate the fuel-flow rate all together. Some fans have been asking the same question. If the teams only have 100kgs of fuel onboard, then what does it matter how quickly or slowly the teams use it? AUTOSPORT has the call:
So why couldn’t we just scrap the entire fuel-flow rate regulation? The FIA has the rebuttal:
“If you have no fuel flow limit, the fastest thing is to use a huge boost at the beginning of the straight and then lift off, said Fabrice Lom the FIA’s head of powertrain.
“There will be huge and very dangerous differences of speed [between cars] on the same lap, with a driving style that is not really F1.
“It was even for us not Le Mans style – which is why we also put a limit on it for Le Mans because we were really afraid of this type of driving.”
The concern over lifting could be an issue as the aerodynamic downforce created by these cars has as much braking power when the driver lifts off the throttle as we do by pushing our brake pedal in our road cars. That disparity between speeds of cars lifting and car tailing the off-throttle car could be dangerous.
What do you think? Is there an easy way to prevent the lifting or cruising in order to save fuel? We have advocated for the last few years that the teams fuel injection rate could be monitored and limited and that would create an engineering challenge for the teams. Not via this fuel-flow sensor but a more sophisticated system that is easy for team and FIA to monitor.
With this limitation, it wouldn’t matter how much fuel you had on board and any additional fuel would only add weight to the car, which is the enemy in Formula 1. So what would be the way to accurately and without deviation, measure the fuel injection rate of a car that all teams and the FIA could get behind? The current fuel-flow sensor clearly isn’t making some teams happy.
