Red Bull Team Principal, Christan Horner, remains adamant that the team complied fully with regulations governing the flue flow rate following Daniel Ricciardo’s exclusion from the Australian Grand Prix.

Ricciardo, who finished the race in second place, becoming the first Australian to win a podium at the Australian Grand Prix, was excluded from the race results following a decision by the stewards after the FIA deemed his car had exceeded the 100kg/h flow limit. They have released a detailed explanation on their ruling, which you can read in full here.

Team boss Christian Horner is confident however that Red Bull will win the appeal against the ruling saying that there was “zero variance” from the 100kg/h limit on Red Bull’s own calibrated equipment which the team relies on since they do not trust the FIA’s own sensor following previous faults with it.

“These fuel-flow sensors that are provided by the FIA to measure fuel have proved problematic down the pitlane since their introduction in testing,” Horner said shortly after news broke of Ricciardo’s disqualification from second place.

“There have been discrepancies and they have been unreliable – indeed some cars may well have run without them in the race itself or failed in the race itself. We had a fuel-flow sensor that was fitted to the car that we believed had an error. Based on our calculation on the fuel that the injectors are providing to the engine, which is a calibrated piece of equipment and is consistently standard across the pitlane, there is zero variance.”

Red Bull are appealing the decision and expect that it will be overturned. “We wouldn’t be appealing if we didn’t think that we had a defendable case,” he said.
