I heard some driver are already on their final power unit? Does anyone have breakdown on who is close to being maxed out?

 

Thanks!

[Exb]

Don't get me started on the damn engine count again (had a bit of a moan about this in the Monaco race weekend thread) - if you go to the FIA website you can find all the technical reports which show how many parts of each of the 6 engine unit each driver has used at the start of each weekend (published the day before FP1) - you can then find the technical reports throughout the race weekend showing who has used a new unit.

However don't expect them to correlate, and seemingly the FIA add or remove new units as they feel like it as they go from one race to the next.

Exb thanks, so it IS hopeless complex! No wonder F1 is engaging few new fans...

Exb thanks, so it IS hopeless complex! No wonder F1 is engaging few new fans...

It shouldn't be that hard to follow, if the FIA lists were correct but they don't seem to be. my initial moan in the race thread was that I noted Seb had used a 4th CE part in Spain yet the PU usage the FIA released on Weds in Monaco had him back at 3 units, someone suggested that it could be he had replaced the part with an older unit in Spain, which I thought made sense, but actually when you read the technical reports its stated as drivers that have used a NEW unit so I'm no longer convinced, I went through all the technical reports (from the start of the season) during the build-up to the race yesterday in the vague hope I might try to understand what was going on - lets just say it confused me even more as some of the pre-race reports show drivers have used extra units when none of the previous technical reports show them replacing that part, sometimes they show a part being replaced over the weekend and yet at the next Grand Prix this is not included in the totals used and there are examples of the pre-race report in Spain showing 3 units used and yet by Monaco the pre race report for the same driver and same part only shows 2 used (Ricciardo and Chilton for CE). After Monaco (if the FIA don't change their minds about who has used a new a unit - or decide the pre-race list was incorrect and change it for Canada then drivers who seem to be close to using their allocation of 5 units are: Vettel (4 CE) he replaced it again in Monaco! Sutil also used a 4th CE in Monaco whilst Kobyashi used a 5th. There are numerous drivers having used 3 units of certain parts (Vettel, Ricciardo, Kvyat used their 3rd ICE, TC, MGU-K and MGU-H on Saturday in Monaco and Maldonado used his 3rd of those same parts in China as well as CE - a side note is it was possibly a TC and MGU-H problem for Vettel that ended his race so he could be in trouble with these parts as well) Both Alonso and Raikkonen are onto their 3rd MGU-H and MGU-K (changed by race in Spain). By Spain Sutil had used his 3rd of all componants (& 4 CE mentioned earlier) but Gutierrez is onto his 3rd only for MGU-H and CE (as are Bianchi and Chilton). Kobyashi has also used 3 ES and Ericson 3 CE. All the Mercedes powered cars are onto their 2nd unit for everything, which they put in in China. Everything else is on the 2nd unit as well except Vergne and Kvyat who are still on CE number 1 and the same two plus Grosjean are on ES 1 as well. But like I said, FIA may change their minds next race - keep an eye out for the technical report released on the Thursday before Canada as it should show the latest usage record which will be a lot easier to follow than this post!

By the way, Exb. That post was so long, it was a joy to look at.

[Exb]

Sorry

[oetzi]

Cheers Exb. Does seem a bit strange - maybe they need a statutory warning: please remember that the numbers of engines used may go down as well as up

[MrMan]

Aren't all these components supposed to be sealed and barcoded? The mind boggles how the FIA managed to screw the counts up!

What is this "powder wunit" thing?  Is that like Super Mario or something?

The Merc PUs look to be pretty reliable, most using only their second or third parts.

Does this help to get the picture clear?

 

(Probably not)

[oetzi]

I was more surprised to see how few parts the Renault teams have used. I guess that answers my unanswered question from earlier this year about whether teams were allowed to repair and reuse damaged components without them counting towards the penalty totals.

[Murl]

Sorry

 

 

Pretty sure you conveyed excellently just how much the PU rationing system contributes to the racing excitement.

 

I thought the war was over now.

 

Throwaway consumer society but no new engines for the pinnacle of motorsports.

[Bleu]

Most confusing part is that CE is divided to multiple parts it seems.

[Exb]

Most confusing part is that CE is divided to multiple parts it seems.

Yes - there appears to be lots of different types of CE - PSU, DCDC, OBI, TRAK, PB, CU, CUK, CUHK (maybe the last 3 are the same?) and replacing anyone of them seems to count as 1 of the 5 new CE.

[RacingDuck]

A few Renault powered cars are on their first part still, I wonder if thats because some of them ran less power, and stressing the parts less. But all of the Mercedes cars are on their second part, or full PU.

[oetzi]

That would make sense if it wasn't for the number of reported failures of Renault PUs. Unless everyone's lying about everything (and it is F1) that must mean that repairs are allowed.

Bad weekend for Kvyat who put in his 3rd ICE, TC and MGU-K on Friday and then replaced them for a 4th part on Saturday.

Also I'm still not 100% sure how the CE are counted, as posted previously there are several different types of CE and the total the FIA are giving is adding up whenever anyone of them is changed, however from the technical reports it appears they have 5 of each type they can change so will be interesting to see if Vettel or Kobayashi get a penalty next time they change a CE part, if not no driver has used more than 2 of any individual type of CE.

example of technical report statement: "The control electronics DC-DC used by the above drivers is one of the five new control electronics DC-DC allowed for the 2014 Championship season and this is in conformity
with Article 28.4a of the 2014 Formula One Sporting Regulations".

[Kristian]

Vettel looks like he'll be in trouble soon... 

 

And the Ferrari teams don't look too healthy either compared to Mercedes. 

[Buttoneer]

According to Scarbs here, Lewis is now on his last set of control electronics.

 

With this failure, Hamilton will have to use his fourth set of control electronics, meaning he has just one more set to use for the balance of the season without incurring grid penalties.

 

Not a power unit, obviously, but the count is still important.  Do we count those here too, or should there be a second thread for those?

[Exb]

Control Electronics (CE on the above tables) are indeed part of the power unit and rack up the penalties once the driver needs a 6th part.

I'm pretty sure Lewis put in a 3rd CE in Canada (meaning a 4th will be required at the next race), so there are still plenty of drivers worse off ;)

 

(Also as I stated above according to the technical reports it seems they have 5 of each type of CE and I don't think Lewis has used more than 2 CE-K or whatever one has failed so if thats the case its not as bad, if it is counted as each time they change anyone CE part then he is in a worse position relative to Rosberg who will take his 3rd CE unit at the next race).

Not necessarily. They could reuse a previously used one, and I'm not sure if a repair is totally out of the question. 

[Exb]

Yes, quite possible to use an old unit - I meant his next one when he takes it would be the fourth and not his final one - your right I shouldn't assume it will be at the next race.

So, excluding control electronics (for which the counts seem odd), these are the most critical issues (used 4 units so far):

 

ICE: Vettel, Kvyat, Bianchi

TC: Vettel, Kvyat, Bianchi

MGU-K: Kvyat

MGU-H: Räikkönen, Bianchi

Edit: They still can't seem to work out how to count the electronics

 How do they come up with that???? Virtually none of them that used an extra CE in Canada have been added on (except both the Ferrari cars and Grosjean).
 
 
From my calculations (going on the technical reports from the FIA website) it is mainly the CE that are wrong, with drivers having used more units than shown on that table - those totals give 1 less unit for SV, DR, LH, KR, JEV, DK, JBi, KK. 2 less for AS and 3 less for MC than if you add up all the technical reports from the start of the season. (sometimes 2 wrongs have corrected themselves eg Ricciardo had mysteriously used an extra CE by the start of the Spainish GP weekend but then the FIA didn't add on a unit for Monaco, so that evened itself out - although they have now not added on 1 he used in Canada so he is still 1 less than he should be).
 
There are a few drivers (PM, EG, ME) that according to those totals have used 1 extra ES unit than if the technical reports are added up. The Thurs report in Malaysia showed PM and ME already having used 2 units but there are no technical reports from Australia showing them using their 2nd and same with EG - The Monaco Weds report showed him having used 2 but no previous report showed him changing to his 2nd unit, unless I missed one (which is more than possible). I can't imagine the teams will let the FIA get away with adding on units if they have not used them so I will keep an eye on it to see if those 3 are corrected in the future or if I did just miss them. 

[balmybaldwin]

At a guess the discrepancy in the CE numbers is because they are repairing and re using old ones?

[Exb]

No I don't think so - the FIA only put in the technical reports who uses a NEW power unit - the teams are able to swop old units but that won't be in the technical reports.

I DON'T FOLLOW FOOTBALL, I LIKE CAR RACING.

[chipmcdonald]

I know you guys in this thread think it's great, but to me a new low point happened in F1 this weekend with the shot of Anthony Davidson being shown in front of the screen of the matrix of Who Has Used What Parts the Most and What Is Left.  

 

That is such a pile of non-car racing rubbish it's unbelievable.  Am I in school again, why am I seeing a RACE CAR DRIVER standing in front of a chart, explaining who has how many parts left they are allowed to use, when I'm suppose to be watching CAR RACING?  WTF???

 

 

[f1RacingForever]

These charts really highlight the stupidity of the current regulations. Half these teams will be receiving grid penalties well before the end of the season. They clearly misjudged how durable these parts would be.

[chipmcdonald]

I really , really don't look forward to the bureaucratic mess the second half of the season will bring, with having to keep up with who is going to get what penalty.  If Redbull gains performance back, it won't matter - on track if they're winning, they won't actually be winning, will they?  It's bad enough Gutierrez has to start at the (further...) back because his team messed up, it's going to be worse knowing that the race will be hamstrung from the start because somebody used up their turbos or some such nonsense.

 

Let me see... can't hear the cars so I can hear what the driver is doing with the throttle, brakes are a mash up of mechanical and computer assisted, you don't know who is saving fuel when, or if they're making a pass because their battery is charged and the other guy's isn't, and now we're going to start seeing races where it doesn't matter what the performance is in the race - the driver is doomed beforehand because he had bad luck *previously* with his engine.

 

Why am I watching this?  I can't really know what is happening unless I have a spreadsheet in front of me, AND all of the telemetry from the cars so I know who is running what fuel/strategy, and I can't hear the cars - even if I could, the sounds don't match what the driver is doing.  So by the end of the season, I'm going to be seeing something on tv that looks like cars going around, except I won't have any idea as a viewer what is really going on , and the value of what I'm watching depends on a chart showing me which driver's penalties... which will make the actual outcome superfluous.

 

CAR RACING?

 

Arghh..

New units used on Friday:
http://184.106.145.7...cument - 11.pdf
http://184.106.145.7...cument - 16.pdf

Most noticeable is Kvyat using his 5th (and final) ICE and MGU-K

[Wuzak]

The teams will rotate the PU components through the season.

 

They could, if they so desired, have run 5 ICEs in the first 5 races. Then rotate them through the season as needed.

 

The only issue is if some of the components have actually been damaged. I think Vettel has had more damaged parts than anybody.

[chrcol]

The Merc PUs look to be pretty reliable, most using only their second or third parts.

 

really?

 

2 failures today in FP1/2, on  top of numerous issues for lewis and some other merc teams.

 

Ferrari clearl the most reliable, renault and merc seem about equal.  But renault getting more headlines due to their performance issues.

These charts really highlight the stupidity of the current regulations. Half these teams will be receiving grid penalties well before the end of the season. They clearly misjudged how durable these parts would be.

 

Or they judged it perfectly and knew that it would become a lottery.  That would line up with every other stupid idea they have enacted or proposed lately.

Not sure I agree with that - Merc have had a few failures BUT they have used less units - therefore their units will have higher milage and be closer to the end of their life anyway.
