The explanation I have heard is that it is a problem with the shape of the fuel tank stopping the pump from efficiently getting the last of it out. It's not that they ran out of fuel; it's that the pump couldn't get it out.

Hmmm, is the shape of the fuel tank something that can be changed quickly or is this going to be a problem this weekend I wonder

Depends on why it is that shape, I guess. But the teams usually don't run the tanks to capacity, so presumably they can put extra in to compensate at the cost a slightly heavier car.

That would seem to be quite a large oversight if true!

And you need enough fuel to provide the FIA a sample, I'm surprised that they would intentionally run it so tight in the first race and not tell your drivers to ease off if they knew they were on the limit.

I remember Max getting told to lift and coast a bit in the first half of the race. Apparently this fuel reacts differently to various temps too so maybe that had some sort of affect?
 
What are teams like on fuel for Saudi? Previously we've had some tracks/races where they could barely carry enough even with full tanks.

I don't remember Saudi being a big problem last year, but extra 5% ethanol means less energy density.
 
There was a known issue with the pump prior to the race. The FIA knew and offered teams the opportunity to inspect them but RB were one of the teams that chose not to.

A formal public indication that there were concerns came after qualifying in Bahrain in an unusual document from race control.

It told the teams with cars in Q3: "For this event only and in contradiction to the requirements of Article 40.6 of the FIA F1 sporting regulations, you will be allowed to delay the covering of your cars one hour later than required in order to inspect the SSC fuel primer pump."

In other words that extra hour before the cars went to bed overnight was provided expressly so that as a precautionary measure teams could look at the primer pump (cars not in Q3 could be inspected during the final session).

However, no overnight pump changes were noted by the FIA when the list of parts changed in parc ferme emerged just before the race.

E10 combusts differently to “normal” fuel, so that hotter reaction will definitely catch people out this season.

You really think the engine manufacturers working in extremely close relationship with the fuel manufacturers would not know how to design, build and tune the engines to cope with the new fuel?

Shell in conjunction with Ferrari were definitely working with the new fuel back in 2019.

I would be certain Mercedes and Petronas were doing the same thing at the same time.

I didn’t say that :confused:

The way the turbo system is split, it is already running extremely hot (between two banks of the engine), so I do think it’ll catch people out.

Well it has caught you out obviously.

Running E10 in F1 engines helps cool combustion and other areas, NOT make them run hotter.
 
That’s not what they kept saying in commentary, but I accept I may be wrong.

The commentary was saying the ethanol part of the fuel reacts differently at different temps and they were speculating that when it's temperature rose it could start to separate out from the normal fuel.

I will listen to the experts at Shell over commentators.

https://www.google.com/amp/s/www.mo...development-battleground-engines/4773054/amp/


Shell's F1 development manager Benoit Poulet told Motorsport.com: "The interesting aspect of the car performance is similar to when you put a [ethanol based] cooling gel on your fingers – you can feel the cooling effect that you get. It will be the same for the engine.

"It will be able to cool some parts of the power unit and that could be quite beneficial. We are working hard on it.

The properties are certainly quite interesting for combustion, and I think we can do some interesting things. We have definitely found at the moment that this cooling effect is good for the engine.

Personally, I think the fuel pump is a red herring. The way they both stopped so evenly, and with with Perez's wheels actually locking up, doesn't look like fuel starvation to me.

I bet they know exactly what is was. My guess, their engine burned oil at a slightly higher rate than expected and they ran dry.

The cooling effect of ethanol is evaporation, where is it doing that in the engine?

As soon as it is out the injector ;)

as to Davide's commentating, I can't help but feel it would be assisted by a little pic-in-pic of him real time. We all know 95% of Italians' passion comes across as hand gestures, it must have been a sight to behold!

Indeed, wouldn't surprise me.

Don't ask me I am not an expert, if the guy from Shell is saying it, I am sure it must have some validity.

The way Ferrari are performing, so far this year, I would say between them and Shell, they have got something right.
