The teams in Formula 1 must install a mandatory second fuel sensor on their car from next year. The FIA car federation announced this on Thursday.
Thanks to the second sensor, the FIA has more options to monitor the fuel consumption of all cars. The sensor ensures that the teams consume a maximum of 100 kilograms of fuel per hour. It is the third technical guideline for the coming racing year that the FIA issues in four weeks.
After the Brazil Grand Prix last weekend, the FIA investigated three fuel systems: one from Ferrari, one from the Ferrari factory team and one from a non-Ferrari engine. However, it is not clear whether the measure is a response to the control in Interlagos, Brazil.
In Formula 1, rumors have been circulating for weeks about the power of the Ferrari engine. According to Red Bull, Ferrari would use a trick whereby the 'fuel flow meter' - an instrument that measures the amount of gasoline used by the engine - sometimes does not record everything. This meter should actually indicate that an engine uses more than the permitted 100 kilos of fuel per hour.
Probably Ferrari circumvented this by laying a high-voltage cable from the hybrid system along, causing the meter to be disrupted. Max Verstappen judged that Ferrari "cheated" that way. The Italian team denied all allegations.
