FIA puts fuel flow spotlight on Ferrari, Mercedes

Ferrari and Mercedes will be in the FIA’s spotlight this weekend in China.

Some weeks ago, we reported that the governing body had told teams that the fuel flow rules would come under closer scrutiny from the Chinese grand prix.

Until now, the rules have been policed with the use of a standard fuel flow meter, but the FIA reportedly now wants to check pressure in other parts of the fuel system.

The Paris federation reportedly suspects that some teams and manufacturers are finding their way around the 100kg/h rule by increasing fuel flow in areas other than the actual meter.

The spotlight is shining most brightly on Mercedes and Ferrari, given the obvious step both engine manufacturers have made in 2015.

Spain’s Marca sports daily reports: "From Thursday in Shanghai, the FIA will use a new set of sensors to measure the fuel system in more detail."

Another Spanish newspaper, El Confidencial, added: "If anyone has managed to exploit a loophole, then they will suffer the effects from China."
