Red Bull RB18

What is interesting is the fuel pumps gradually failed. Both drivers reported a loss of power.
Could there be some relation to the fuel level in the tanks?
Another remote possibility is vapour locking.

Can low fuel flow be used as a signal for the mgu-k to kick in and store energy?

That would explain the erratic red light blinking on and off from the back of the cars.

It makes sense to store energy when lifting and no fuel(no throttle or low throttle) means lifting.

Wasnt it the mgu-k that malfunctioned on the third Honda too?

AMUS has an article that mentioned the E10 fuel causing issues for teams during testing cracking the resin the fuel pump is encased in and killing the electronics, that could explain the erratic lights and, the reported issues with Macs wheel displaying erratic messages (iirc)

So a couple of things

1. If RB are three tenths down but are still overweight by 10kg, is this the quickest way of equalising the difference?

2. RB seemed to have a massive advantage on the straights, should they not have put on more downforce for the corners?

3. Can Honda increase the acceleration performance through MGU-K and the electronics before they are frozen in September?

4. Max said he didn't have the same feeling in the car during FP2 on long runs vs today on long runs so hopefully performance can still be found?

1. Yes
2. Yes
3. No. MGU-K output is capped at X Kilowatts. (Although the delivery can be "modified" for traction, like a very crude "launch control".)
4. They will hope so.

But, although the max power is limited, the duration it is used isn't. So with better harvesting of energy, the deployment can be over a longer period per straight, thus aiding in acceleration (the PU can accelerate longer with both ICE and MGU-K on the beginning of a straight, before the MGU-K builds off). So, imho the answer is yes.

If it is a problem of the E10 eating away the resin, it is a baffling coincidence it happened in the last Laps. While a theorie about a relation with low fuel might have some merit, wouldn't there be a much simpler way to explain what happened? Could they have just run out of fuel?

It was a fuel supply issue. The fuel pump suspicion would be an easy thing to tell to the camera's if you did something stupid and know there were issues with the pump.

There was a "3-stop surprise", with higher average laptimes than anticipated. Both Ferrari drivers staded that they were just managing the gap behind in the last stint. (With a New car and not much outlook on a position change they could be very eager to stop pushing and galvanise) With both RB's in fuel saving mode, it would be LH dictating the pace of the top 5.

If it was the pump; prior to the race teams were geven the opportunity to inspect it. There are some articles suggesting RB might not have done it. But what if they did, and RB can give clear evidence it failed on all 3 Honda 's by no fault of their own. That would place the FIA in a tough spot, with 15% of their fleet out of the race due to a faulty component they supplied, including a possible substantial influence in a championship. They could be forced to neutralize the outcome.

Or just. Out of gas. . Could be...
If so they ran the engine in too high power setting....

I recall quite early in the race Max was told to "lift and coast", at least Sky's folks said so.

Because the brakes were overheating. Later in the race he was told to push till the end.

According to AMuS RB has stated very clearly there was fuel left in the tank. It is also hinted that RB did not do many low fuel runs in testing so might have been caught by surprise with this issue.

Could tie in with their emergency fuel system check request to the FIA overbight after qualifying. Saw something they hadn't seen before after proper low fuel runs?

Also, RB tend to not be the most transparent when it comes to the reality of difficult situations, so we'll have to wait and see I think.

There must have been some left for the FIA test, or doesn't that apply if you DNF?

No sample is required after a DNF.
What would be the point? Even if there wasn't enough, it would get you disqualified from a race that you didn't finish. The didn't finish is punishment in itself, isn't it?

[gandharva]

They need to get on top of the brake issues, otherwise both drivers won't be able to fight. After 2 attacks he already had to back off due to overheating.

Fuel pump problem is probably minor, but hurts even more if so.

Aren't the brakes and brake ducts standard parts now?
