The FIA will be introducing mandatory fuel flow meters to the FIA World Endurance Championship’s GTE Pro class before the end of the 2018/19 ‘Super Season’.
This change to the regulations comes after the “unanimous agreement of LM GTE Pro Manufacturers”, according to the FIA, and 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.
The FIA hasn’t yet offered a public explanation for the change, although it is important to note that the addition of fuel flow meters to the cars comes as 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 Sensor.
“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
by FIA. The FIA’s requirement is to mount the sensor as defined in the 2018 LMP1 Technical Regulations.”
