The FIA have added a set of directives to measure the fuel flow pressures in multiple places within the fuel system.
The reason being is because the FIA think certain teams (Mercedes and Ferrari) are both getting round the fuel flow restriction by basically having a secondary much much smaller tank where by after the fuel has passed through the fuel flow sensor it can accumulate some extra/excess fuel within this tank (or just within the pipes) and then during points of coming out of corners, starting line straights, overtaking the team can use this reserve to inject extra fuel into the engine thus making them faster at those points.
Teams must comply with the new directive before the Chinese Grand Prix in April.

Clever idea if it is true.

Not that genius actually, it's one of the workarounds we discussed late 2013 early 2014 as a solution. I think we agreed that since the fuels is being "measured" and then not used, but simply stored to be used at a another time makes all the sense in the world. it's still very much complying with the 100 kg per hour flow rate so what they do with it afterwards is nobody's business.  I hope though that this isn't something that causes an even wider gap to the Merc boys. It does have all the earmarks of a Red Bull complaint so perhaps there's something to it. |

Teams must comply with the new directive before the Chinese Grand Prix in April. It's actually more likely to be Ferrari and not Merc that are exploiting this. Merc had a 250 bar fuel injector last year but Ferrari had the max permitted 500, which Merc have just introduced. Ferrari had enough problems last year with drive ability to have made proper use for fuel flow higher than 100 per hour. And Merc are not likely to have had the need due to their superior power even with the lower boost system. The way I read it is that even when the engine doesn't need the max 100 rate it forces it and then caches the unused instead of return it to the tank. Then later it can use the fuel to go above the 100 rate, but this would only make sense at the highest permitted boost rate and hence highest revs This is great for an engine that is not completely sorted thru the revs for smooth optimised power delivery. Like Ferrari or Renault last year at first race. This year only Ferrari and Merc have the max 500 bar boost so I suspect Ferrari will suffer a lot more than Merc come the China GP |

I suppose this is one of those things that falls under the category of "No one told us we couldn't do it...so we did."
Brilliant fun!

Without a doubt this will be a Red Bull complaint. They got caught basically inducing the same outcome, and blamed the FIA sensors. But Renault are the only maker this year without the 500 bar fuel injectors, and therefore are the one team that dont have the ability to inject this 'cached' fuel at higher revs. So they cheated to increase flow rate by just doing it in full view of the FIA sensors, and are now complaining about others doing it cleverly beyond the FIA sensors. The most likely outcome is to increase the gap between Ferrari and Merc, and once again RBR have shot themsleves in the arse like they did with the unfreeze leading to Renault holding back at the start of the season. |

Toto's response will be, "Oh, so you want to try to complicate our lives. How about we turn up the AMG PUs another 80 to 110 hp? Just for the fun of it, of course." Such fun! |
