Porsche has been outspoken in its criticism of the ultrasonic fuel flow meter used in Formula 1. The German marque will use the meter in its new 919 LMP1 this year. In the LMP1 category gasoline fuelled cars must run with two sensors identical to the units at the heart of Red Bull’s disqualification from the Australian Grand Prix. Cars running on diesel fuel must run three, but Porsche says that there is ‘no robust solution’ to the measuring process and doubts that there will be this season.



‘It hasn’t held us back because we did not make our development dependent on it, but there is still no robust solution in place,’ said Alex Hitzinger, Technical Director of LMP1 development at Porsche. ‘The FIA is still very hopeful that the latest spec will work and will be reliable, but that is not proven yet. We optimise how they are mounted to give them the easiest possible life, but right now we don’t know if it is all going to be robust. We should know at the end of March.’
