The FIA has announced that it will introduce mandatory fuel flow meters to the GTE Pro class of the FIA World Endurance Championship before the end of the 2018/19 ‘Super Season’.
This change to the regulations comes after the “unanimous agreement of LMGTE Pro Manufacturers”. It will be recommended for next week’s FIA WEC 6 Hours of Spa-Francorchamps, the penultimate round of the season, before being enforced (“until further notice”) ahead of next month’s the Le Mans Test Day and the season-ending Le Mans 24 Hours.
Currently, there is no reasoning given by the FIA publically for this change. Importantly, this is a form of monitoring and not a means of restricting to the Pro cars’ fuel flow.
The FIA bulletin explains that: “the fuel flow will be measured using, as a prime measurement, a homologated* Fuel Flow Sensors.
“A homologated* sensor, to be usable during a race event, must be calibrated by a homologated calibration company.
“This calibration must be done for each single fuel and after each modification done on the sensor unless advised otherwise
“The FIA’s requirement is to mount the sensor as defined in the 2018 LMP1 Technical Regulations.”
The LMP1 EoT for the 6 Hours of Spa-Francorchamps has also been revealed. All three documents relevant to this story can be found below.
