The stewards' decision in full:

The Stewards, having received a report from the Technical Delegate, heard from the team representatives, have considered the following matter and determine a breach of the regulations has been committed by the competitor named below and impose the penalty referred to.

No/Driver: 3, Daniel Ricciardo

Competitor: Infiniti Red Bull Racing

Time: 20:17

Session: Race

Facts: Car #3 was not in compliance with article 5.1.4 of the FIA Formula 1 technical tegulations.

Offence: Breach of article 3.2 of the FIA Formula 1 sporting regulations and Article 5.1.4 of the FIA Formula 1 technical regulations.

Decision: Car #3 is excluded from the race results.

Reason:

1) The technical delegate reported to the stewards that car #3 exceeded the required fuel mass flow of 100kg/h. (article 5.1.4 of the Formula 1 technical regulations)

2) This parameter is outside of the control of the driver, Daniel Ricciardo.

3) The fuel flow is measured using the fuel flow sensor (Art. 5.10.3 & 5.10.4 of the technical regulations) which is homologated by the FIA and owned and operated by the team.

4) The stewards considered the history of the fitted fuel flow sensor, as described by the team and the technical delegate's representative who administers the programme. Their description of the history of the sensor matches.

a. During practice one a difference in reading between the first three and run four was detected. The same readings as Run 4 were observed throughout practice two.

b. The team used a different sensor on Saturday but did not get readings that were satisfactory to them or the FIA, so they were instructed to change the sensor within parc ferme on Saturday night.

c. They operated the original sensor during the race, which provided the same readings as run four of practice one, and practice two.

5) The stewards heard from the technical representative that when the sensor was installed on Saturday night, he instructed the team to apply an offset to their fuel flow such that the fuel flow would have been legal. He presented an email to the stewards that verified his instruction.

6) The technical representative stated to the stewards that there is variation in the sensors. However, the sensors fall within a known range, and are individually calibrated. They then become the standard which the teams must use for their fuel flow.

7) The team stated that based on the difference observed between the two readings in P1, they considered the fuel flow sensor to be unreliable. Therefore, for the start of the race they chose to use their internal fuel flow model, rather than the values provided by the sensor, with the required offset.

8) Technical directive 01614 (1 March 2014) provides the methodology by which the sensor will be used, and, should the sensor fail, the method by which the alternate model could be used.

a. The technical directive starts by stating: "The homologated fuel flow sensor will be the primary measurement of the fuel flow and will be used to check compliance with articles 5.1.4 and 5.1.5 of the F1 technical regulations..." This is in conformity with articles 5.10.3 and 5.10.4 of the technical regulations.

b. The technical directive goes on to state: "If at any time WE consider that the sensor has an issue which has not been detected by the system WE will communicate this to the team concerned and switch to a back-up system."

(emphasis added.)

c. The back-up system is the calculated fuel flow model with a correction factor decided by the FIA.

9) The FIA technical representative observed thought the telemetry during the race that the fuel flow was too high and contacted the team, giving them the opportunity to follow his previous instruction, and reduce the fuel flow such that it was within the limit, as measured by the homologated sensor - and thus gave the team the opportunity to be within compliance. The team chose not to make this correction.

10) Under Art. 3.2 of the sporting regulations it is the duty of the team to ensure compliance with the technical regulations throughout the event.

Thus the stewards find that:

A) The team chose to run the car using their fuel flow model, without direction from the FIA. This is a violation of the procedure within TD/01614.

B) That although the sensor showed a difference in readings between runs in P1, it remains the homologated and required sensor against which the team is obliged to measure their fuel flow, unless given permission by the FIA to do otherwise.

C) The stewards were satisfied by the explanation of the technical representative that by making an adjustment as instructed, the team could have run within the allowable fuel flow.

D) That regardless of the team's assertion that the sensor was fault, it is not within their discretion to run a different fuel flow measurement method without the permission of the FIA.

The stewards find that car #3 was out of compliance with the technical regulations and is therefore excluded from the results of the race.

Power.

Not economy. The economy part is the fact they only have 100 litres to start and finish the race with.

Fuel flow restricts the maximum power available from the turbo motor. Otherwise with an unrestricted flow, you could run massive power to pass at will, then just trickle around to save fuel.

Yeah you have to laugh at the mainstream medias attemps to explain what the hell it was he got pinged for. Hopeless. Still brilliant effort by Dan none the less. He just needs to repeat it in a couple weeks and he is on his way to crushing Tool.*

Also good effort by Magnussen. Pretty young looking podium, all up.

*May have gone a bit early with that prediction.

It was a little strange seeing the McLaren not make much ground on the RB down the straight, when all the talk was about how slow the Renault was in a straight line.

Overall it's a sad state of affairs for a sport that revived such a PR boost in this country with Dans result. Not saying it could be over looked for the PR, but it's just sad.

I skimmed over that stewards report, makes me very uneasy about these fuel flow meters for "parity".

Back in the eighties they used to have the same issues with the boost limiters (bovs basically if i remember correctly) they used to limit the turbo motors. FIA stuff was not up to scratch and the teams quickly figured out how to game them anyway.

Lets see Vettel get a good weekend in and see if Dan can ruffle feathers. It does look like being a race for the 3rd step between RBR, Williams and McLaren which will make for interesting racing. But Mercedes are clearly quicker much like Seb was in Singapore last year. Pace to burn.

RBR are probably, in leagalese, screwed; but we'll see

To clarify, it turns out not to be L/h fuel flow (volume) but rather mass flow (kg/h)

Depending on the specific gravity of the control fuel and the ambient temp, 100kg/h would probably be between 110-120L/h (?)

here's an excellent picture for all you Kobi fans out there

rajab knows why you're fans, but you deserve pics regardless

yeah bag him because his rear brakes didn't work.

fans because a Caterham has never been far enough up the grid to crash into anyone before!

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
